2012 is the year for market share of China jaw crusher
With the progress of accelerated urbanization construction, the construction
waste has been became a problem that impede city development. As the main
equipment processing construction waste, the jaw crusher from China made
great contribution to the construction industry. Construction waste is entirely
possible to be recycled by jaw crusher from China. Scrap steel, scrap steel and
other scrap metal materials can be processed and directly reused or recycled. So
the demand for jaw crusher from China in the construction market has been
increased in 2011. In 2012, HXJQ will take more efforts to develop and research
new type jaw crusher to meet the need of different consumers.
For the waste concrete, people can use jaw crusher from China as the coarse
crushing step, the processed construction waste can be used to be the base of
road. As well as other building materials, such as floor tile, wallboard and
concrete material. Because construction waste dumping more concentrated, the
site is limited, and transportation is not very convenient, many consumer
suggested use of jaw crusher from China. This jaw crusher produced by HXJQ
company can be used for a variety of large-scale multi-stage crushing bulk
materials. The jaw crusher from China can save a lot of infrastructure and
relocation costs.
Hydraulic mininig equipment expands brilliantly like phoenix winging
China's hydraulic mining machinery industry and the world advanced countries
there is a gap, and the gap is our great progress space, in order to be able to
reach the world advanced level, only recognize the difference, the gap from
place to start, and constantly improve their standards in order to continuously
improve our ability of hydraulic mining machinery. Let us first analyse our
country and the advanced countries in the world in hydraulic mining machinery
industry gaps.
Hydraulic network of excellence senior consultant hydraulic Li Gong from the
current point of view, the domestic mining industry science and technology
foundation is thick, and the field of the mining machinery has been change a
technology with the market as a way to improve the level of product technology
is not phase, and to face the foreign competitors, especially the foreign
competitors in the domestic investment and set up factories in the grim
situation. Therefore, the domestic mining machinery enterprise innovation
consciousness forced excitation.
Domestic major mining machinery R & D and exporters in Shenzhen city of
God extension mechanical and electrical equipment limited, enterprises in the
face of domestic and foreign innovation competition of enterprises, after years
of rapid adjustment, now Shanghai state of the world has been established,
complement and perfect the advantage domain application research and development
base, launched to crusher, milling machine and system sand machine as the main
products, manufacturing process and process technology application research.
Shanghai world Bang after the pioneering and innovative ways, practice, research
and development of new products, to meet the mineral resources of mining
machinery made more specific, more explicit content of innovation, in recent
years the company's R & D results: tracked mobile crusher station, a
mobile mobile crusher station, PFW European version of deep cavity hydraulic
crusher, JC the European version of jaw crusher, cone crusher, CS HPC hydraulic cone crusher,
sand making machine, the
new VSI VSI5X centrifugal impact
crusher, V.W high grade stone shaping machine, MTW Euro trapezium mill, LM
large vertical milling machine, SCM superfine milling machines and other
equipment are energy saving, water saving type, comprehensive utilization,
environmental protection of mining machinery products, and can give the
operators to create a safe and comfortable work environment.
So, our country and international developed country the main reason of
difference of existence or technical level. China in the innovation and
international developed country manufacturing level is still a gap in the
domestic challenges, so great. Domestic and foreign mining machinery gaps exist
for many reasons, including market demand differences are caused by a gap
between the objective reasons, due to the international market for excellent
mining machinery manufacturers focus areas in Europe and the United States,
where large-scale basic construction stage has in the past, the market for
aggregate demand is not much, and environmental protection requirements are
high, certainly will forms gravel field height focus on large-scale production
to achieve environmental protection, they required mining machinery
specifications, strong maneuverability, high automation process think. To meet
the market demand for the development of the mining machinery and domestic
product is not the same as, as we are at the large scale infrastructure
throughout the period, the demand for mineral resources mineral resources
increase, investment caused by heat, blossom everywhere mines are often small in
scale, but started fast, less investment, the market demand so crudely made,
technology level is low, energy consumption high, serious environmental
pollution products have entered, but these devices are often only at low prices
to capture the market, so with the international advanced level
difference.

Structures and functions of various conveying machinery
Belt conveyor is
a kind of friction drive by the continuous mode transportation machinery
materials. Application of it, the material can be in a transmission line, from
the initial material to the final point of discharge is formed between a
material conveying process. It not only can be broken loose material conveying,
can also be carried into pieces of goods transportation. In addition to the pure
material handling, but also with various industrial enterprise production
process in process requirements are matched, formation of rhythmic flow
transport line. The belt conveyor is widely used in modern industrial
enterprises.
In mine underground tunnel, mine transportation system on the ground, open
pit mining field and ore dressing plant, widely used in belt conveyor. It is
used for transport or incline transportation. Common belt conveyor by the
conveyor belt, roller, roller and a driving, braking, tensioning, modification,
loading, unloading, to cleaning device.
Belt conveyor technology:
The first is the reliable operation of belt conveyor. In many continuous
operation of the important production units, such as power plant of the
transportation of coal, iron and steel plant cement plant and bulk material
conveying, and port handling of ships were using belt conveyor. In these
occasions such as shutdown, the loss is huge. When necessary, belt conveyor can
be a class with a class of continuous work.
Belt type conveyer power consumption is low. Due to the material and the
conveyor belt with almost no relative movement, not only make small running
resistance (about the scraper conveyer 1 / 3-1 / 5), but also to the load of
attrition and fragmentation are small, high productivity. These are beneficial
to reduce the production cost.
Belt conveyor line adaptable and flexible. The length of the line is set
according to the need. The short several meters long, can reach more than 10km.
Can be installed in a small tunnel, also can be mounted on the ground traffic
chaos and danger area in the sky.
According to the process requirements, belt conveyor can be very flexible to
from one or more points by feeding. Can also provide more or sections of
unloading. When simultaneously at several points to the conveyor belt material
(such as coal washery coal bunker under the conveyor belt conveyor) or along the
length direction on either through uniform feeding device to feed conveyor, belt
conveyor has become a major transportation route.
Belt conveyor in coal storage yard stockpile below the roadway reclaimer,
when needed, but also the different material for mixing pile. The material can
be simply from the conveyor head unloading, also available through plough type
unloader or mobile unloading vehicle in the length direction of the conveyer
belt with any point discharge.
Screw conveyor or auger, suitable for granular or powdered material conveyor
of the horizontal, inclined conveyor, vertical conveyor and other forms of.
Transmission distance varies according to deformity, usually from 2 meters to 70
meters.
Principle of transport: rotation of the auger blade passage for the material
screw conveyor. The material and the spiral conveyor leaf rotation force is the
material of its own weight and screw conveyor casing material friction
resistance.
Structural features: screw conveyor rotating shaft is welded with a helical
blade, blade face delivery of materials according to different entities of type,
belt type, leaf type and other types. The spiral shaft of the spiral conveyer in
the direction of the material movement of the terminal with the thrust bearing
with material to spiral axial force, the captain a long time, should be added
the middle suspended bearing.
Double screw conveyor is two are respectively welded with the rotation of the
rotary blade shaft of screw conveyor. Bluntly, is two screw conveyor are
organically combined together, form a spiral conveyer.
Screw conveyor rotation axis of rotation to, determines the material
conveying direction, but generally screw conveyor in the design are designed
according to individual carrier rotating blades. When the reverse transmission,
can greatly reduce the conveyor life.
Bucket elevator: using uniform is fixedly connected to the endless traction
member on a series of vertical lifting material hopper, the continuous conveying
machinery.
Bucket type lifting machine has large conveying capacity, high lifting
height, stable and reliable operation, long life advantages, its main properties
and parameters with the JB392685 'vertical bucket type lifting machine' (the
standard equivalent with reference to the international standards and advanced
foreign standards), traction chain with MT3680 'mining high strength ring
chain', the lifting machine for conveying powdery, granular and small block of
wear resistance and wear resistance of small material, such as: coal, cement,
stone, sand, clay, minerals, due to traction hoist is a circular chain, thus
allowing delivery of high temperature of the material (the material temperature
not exceeding 250 degrees Celsius). General transport height up to 40
meters.
For surviving mergers and acquisitions are popular in mining industry
Recently, non-ferrous metals industry, the introduction of macro-control
policies frequently, mine as the source of the industrial chain, energy saving
throughout the process in an important position. Mining machinery as a
practitioner of energy saving, the efficient use of resources will greatly
facilitate the re-use of mines, not only take resource-saving and environmental
protection-oriented sustainable development, and reached the 'two sessions'
advocated taking carbon reduction row of the policy requirements.
Investment Advisor in Senior Fellow in China, said He, the data show, the
annual international mining machinery in the rising value of the state, but the
Stock Watch the domestic market is still small, is typical of inward-looking.
Although the domestic market is vast, but in an increasingly competitive
international market, the domestic mining machinery is still in a weak position.
This weakness is mainly reflected in the large but not strong, despite the
variety of industries, production has reached a certain amount, but the overall
quality and innovative technology breakthroughs, there are still large
obstacles.
The next round of price war is the war developed, the product chain and
service competition, channel competition, competition and other business
conditions are the subject of future international competition, domestic mining
machinery industry, diversification of the status quo is not enough to enter the
competitive market, Therefore, during the second five, the domestic mining
machinery market will enter a new phase of the upgrade. Large market and demand
in the Chinese market are transferred to the case, among the Chinese market will
be the forefront of the international market.
According to the Investment Adviser's '2010-2015 China mining machinery
industry investment analysis and forecast report' shows that the world's top ten
manufacturers of mining machinery accounted for 85% market share, control of the
whole industry is concentrated in a few companies. From the world's mining
machinery industry in the future development trend, the natural environment for
the harmonious development requires mining machinery 'eco', the product
throughout the life cycle does not produce environmental pollution or
environmental pollution, minimize the maximum resource utilization, the lowest
energy consumption, the ultimate economic and social benefits to achieve the
coordination of business is the company's future development.
Investment Advisor in the Research Director Zhang Yan Lin pointed out that
the construction machinery market is a financial services industry through a
variety of channels into all aspects of the same, in terms of mining machinery,
finance leases in the sale of shares in the proportion is increasing year by
year, in accordance with international Analysis, part of the mining corporate
finance leasing business has accounted for 60% of the sales market over the next
period of time, domestic enterprises will use this as the goal, to develop
financial services, mergers and acquisitions boom gradually approaching, the
domestic market or mining machinery will face more opportunities and
challenges.
Diversified development are making Mining Machinery reach the peak
Construction machinery concrete machinery as important board piece, huge
market demand and industry rapid development, promote enterprise to accelerate
investment market, with the acceleration of investment, the competition between
enterprises is growing. At present, the market's investment to the irrational
development trend, market worries still strong. Investment in infrastructure
drop basis, despite fears rise, bibcock enterprise investment growth
unabated.
The consultant in machinery industry researcher Duan Jiaxuan pointed out, the
two quarter construction machinery market economy glides, the market in the hope
that the second half of the year the protection of housing construction
accelerated, from at present the market guarantee the progress of housing
construction as well as the present situation observation, bittersweet. Benefit
from our real estate and infrastructure investment grows quickly continuously,
concrete machinery growth expectations, this once again highlighted our country
rely on heavy industry to promote economic growth is inertial still exist.
The investment adviser of director Zhang Yanlin pointed out, and the
corresponding, mining machinery is still more optimistic about the prospect of
the industry sectors, mining equipment industry grows to basically rely on
infrastructure investment, due to China's rapid development of economic
construction, include highway, railroad, real estate, the project is more still,
some time in the future inside, maintain a certain level of infrastructure
investment in 2012 will be the main development power of mining equipment
industry.
According to the investment adviser released '2011 - 2015 China machinery
industry investment analysis and forecast report' shows, in the fierce
competition in the market, market expansion is the enterprise uses generally
competition, market is accelerated, competition also accelerated, and there is
growing trend. Shantui, willow worker enters, plus a group of concrete machinery
industry growing, with 'seek hegemony' of concrete machinery industry for many
years the industry hutch Zoomlion, Sany formed face the competitive
situation.

Tamping the solid technological foundation of machinery productivity
Mountain mechanical applications and infrastructure are closely related, the
future will have a huge market. However, industry believes that the overall
mining machinery in China with the international advanced level compared to 15
to 20 years behind most sources of technology products for the mid-1980s from
abroad. Domestic market share of mining machinery products in the market less
than 80% in the imported products are mostly large, fine, sharp and strong sets
of products, such as coal mining, large efficient separation equipment, crushing
and grinding equipment, all joint cross-section boring machine and other
products.
Mining machinery industry's technological base is not strong, reform and
opening up, has been in the field of mining machinery market for technology to
improve product technology level as the main way. Throughout the world the
development of mechanical design process, mainly stand-alone single product
design to product design to process equipment design process evolution. China's
general mining machinery manufacturing completed only stand-alone product design
and manufacturing equipment used in the design process to do by a professional
institute, the craft of stand-alone product requirements proposed by the
professional design institutes and assist manufacturers to complete, which
resulted in equipment manufacturer and device disconnect between departments.
Experts believe that in the current mining machinery manufacturing industry, the
business process design is relatively weak in the case, good condition, except
in their own areas of expertise into the role of organizational strength as soon
as possible, should be taken with foreign and domestic companies to establish
various forms of professional institute joint, including the formation of
groups, unions, the introduction of technology, the introduction of qualified
personnel and other measures to fight in a joint project on the design approach,
the first intervention and then to improve and achieve win-win situation.
In addition, experts suggest that as quickly as possible, to supplement and
improve the application of the advantages of professional laboratory for
product, manufacturing process and process technology research. Not applied
technical research data and databases, you can not convince customers to use the
company's products and technology, not to mention the truly innovative
application of technology.
Importance and effects of oil in the development of mining industry
Based on the actual characteristics of the situation in the mining machinery,
oil is very strict on the requirements, as follows:
First: As the volume of mining machinery and its fuel tank volume are
relatively small, so it is easy to appear the work of a high oil temperature,
which requires oil to have better oxidation resistance and thermal
stability.
Second: Because the gravel mining machinery working environment is very
harsh, dust, water was relatively large, oil is vulnerable to the contamination
of impurities in the external environment, so the oil must have a good anti-rust
and anti- corrosive. Only in this way by the outside world when the oil in the
case of adverse environmental impact, its performance will not have significant
change.
Third: the working environment of mining machinery and equipment is usually
outdoors, so the work environment affected by temperature changes, especially
the large temperature difference between summer and winter, day and night
temperature difference in some areas is relatively large, so the oil viscosity
must be less affected by temperature, this area requires high temperature, it
will not lead to too low viscosity, but not the line as a lubricant, the other
is to avoid the temperature is low, a result of low oil viscosity Start with the
operation difficult.
Fourth: There are some easy fire or explosion mining machinery, of course,
requires a certain degree of anti-flammable oil, mineral oil can not be used to
fuel for lubrication.
Fifth: The last is certainly better than the seal lubricant to prevent seal
damage and impact on the effect of lubricating oil. Lead to some unnecessary
risk.
How to address the ups and downs in the waves of mining machinery
As people know, mining industry is treated as the most difficult and
dangerous economic activities.
It's the products of this activity that allow society to function the way it
does today. One can only imagine what life would be like without the products of
mining. Daily activities would be hindered without the production of natural
minerals and coal; not to mention its effects on economic activity. Luxuries
like jewelry also come as a result of the mining of precious metals.
Methods have developed greatly over the centuries. Matter of fact, major
developments happen on a daily basis. New sciences and technologies allow the
industry to grow and provide more for the world. Many people are unaware,
however, of the methods and procedures that go into the mining process.
There are two common excavation techniques used today: surface and
sub-surface or underground mining. The more common of the two is surface mining
seeing as it produces a majority of the world's minerals.
Surface mining, as its name might suggest, is the easier of the two. The
technique involves the removal of material that can be found on the surface such
as vegetation or dirt. If necessary, miners dig into the bedrock to reach the
deposits they are aiming for. This technique employs the use of one of five
further forms of surface mining. These include strip, open-pit, mountaintop
removal, dredging, and high wall mining.
Sub-surface mining, on the other hand, is the exact opposite of surface
mining. This technique involves the digging of tunnels deep into the earth's
surface to reach the deposit. The products of this type of process are then
brought out through the tunnels and shafts created. Unlike surface mining, which
is classified into five forms, sub-surface mining is classified by the type of
access shaft used to extract whatever mineral needs extraction.
Advancements in mining equipment such as green light laser technology have
made it much easier for miners to do their work. Most people are unaware that
laser technology plays a big role in the success of any mining operation. Red
light lasers used to be the standard, but green light lasers are starting to
become more widely used. This is because green light is apparently much stronger
than the red light, and is also visible under direct sunlight.
People tend to confuse the petroleum industry as being part of the mining
industry, but this is not the case. It's easy to confuse the two, considering
that the retrieval of petroleum involves the gathering of a product that is
below the surface. Petroleum, however, is not mined like other minerals. This is
because petroleum is in a liquid state; for it to be retrieved, it needs to be
pumped out.
So surely there is no time to delay to solve energy comsumption
In recent days,the temperature has dropped suddenly. Thus the situation of
power shortage eased in China's western Guangxi Zhuang Autonomous Region.
Experts suggest that we should adopt the strategy of protracted war to handle
with this situation. Guangxi needs to change the industrial structure which is
based on high energy consumption industries.
Since this summer,the supply of power is not enough due to dry weather. The
power contradiction in Guangxi appeared a severe power shortage in a red warning
signal, the maximum demand of electricity power shortage about 30%.
Lin Boqiang said that we should increase the capacity of installed machinery
and improve the configuration to deal with the power shortage. We should take
the situation of long-term drought into account and increase capacity of
installed machinery. According to the statistics of Guangxi Power Grid,the total
power capacity is 25.33 million kilowatts,14.94 million kilowatts hydropower,
thermal power 10.39 million kilowatts.
Cement and other high energy-consumption industries are major consumers of
electricity in Guangxi.The commission of industrial development and information
technology show that total electricity consumption is 73.341 billion kw/h from
January to August.Among them, the first industrial power is 1.353 billion kw/h;
second industrial power is 54.553 billion kw/h; tertiary industry is 6.038
billion kw/h.The proportion of aluminum smelting,iron alloy smelting consumption
is high and the power consumption is rising in the industrial electricity.
Hongxing keep the spirit of Adhere To Excellence to keep improving
Recently, non-ferrous metals industry, the introduction of macro-control
policies frequently, mine as the source of the industrial chain, energy saving
throughout the process in an important position. Mining machinery as a
practitioner of energy saving, the efficient use of resources will greatly
facilitate the re-use of mines, not only take resource-saving and environmental
protection-oriented sustainable development, and reached the 'two sessions'

Investment Advisor in Senior Fellow in China, said He, the data show, the
annual international mining machinery in the rising value of the state, but the
Stock Watch the domestic market is still small, is typical of inward-looking.
Although the domestic market is vast, but in an increasingly competitive
international market, the domestic mining machinery is still in a weak position.
This weakness is mainly reflected in the large but not strong, despite the
variety of industries, production has reached a certain amount, but the overall
quality and innovative technology breakthroughs, there are still large
obstacles.
The next round of price war is the war developed, the product chain and
service competition, channel competition, competition and other business
conditions are the subject of future international competition, domestic mining
machinery industry, diversification of the status quo is not enough to enter the
competitive market, Therefore, during the second five, the domestic mining
machinery market will enter a new phase of the upgrade. Large market and demand
in the Chinese market are transferred to the case, among the Chinese market will
be the forefront of the international market.
Strengthen reliable performance: Even open coal mine stripping operations are
easily collapse, it put forward higher request to the materials of mining
machine, in case of dangerous accidents the driver's safety can be guaranteed.
It should be taken into consideration in the machine functions, such as it can
be equipped with a similar small hammer to the bus which can be used to break
glass in dangerous conditions. In addition, mine mining machinery products
closure and escape performance should be improved.
To distinguish whether the large-scale mining machine crash to other
vehicles, changing the mechanical cab is necessary, it can help to reduce the
blind range of the driver and will help improve the mining construction
safety.
At present, in large mining, small cars must insert a red flag to prevent
rolled by large mining equipments. The blind range of some large mining
equipments can reach 30 meters, small vehicle drivers must be careful,
especially in the pass avoiding to close to large-scale mining equipments.
A remarkable characteristic of mine construction is its danger, even in the
smooth road. How to ensure the safety of mining construction, mining machinery,
and development is an important direction of the product.
Focusing on energy conservation and environmental protection: Mining
machinery products are generally in high intensity work environment, many
products are in non-stop mode of operation except during product maintenance
time every day. Running more than 20 hours on boot operation is a test for the
performance of the product. A customer once said, some manufacturer promise him
that the product can be used for six years, however, in a mining field, three
years is the maximal utilization period. Customer's request for the product is
reliable, the product can to maximize efficiencies in the shortest possible
time. For mine which highly dependent on equipment performance of construction
environment, product reliability is an important aspect of mine head
attention.
To improve safety performance: Mining area is not worry about the number of
devices, and in many mines, we can see in the soil to dump truck loaded
excavator, often have several cars in the queue which makes the vehicle without
full capacity, it causes the waste of resources.
In the mine internal construction, dump truck is one of the largest usage
product. Since last year, some Chinese companies marched into mine dump truck
field, mining transport equipments as big main development direction are more
obvious. It is likely that in several years later, equipments below 30 tons
capacity will not be permitted to enter mining construction site.' Chairman of
Inner Mongolia ZhunGeErQi kun gold machinery engineering Co., LTD Yu Guojin
said. Creating more economic construction in a short period of time is the focus
of mine construction . The products are made to improve work efficiency. Users
calculation of the economic benefit of mining machinery products is important,
the most careful 'durable ' is always the first requirements. In a recent period
of time, the reporter has been to Inner Mongolia, Qinghai's to investigate, they
discover customer's need of the product has a very distinctive
characteristic.
Criteria to choose mining equipment in stiff competition
There is a vast range of mining equipment available, dependent on the
application for which it is to be used. Underground mining, surface mining and
open pit mining all require the initial movement of large quantities of earth.
This equipment is similar to that used in large building projects, in the form
of dump or haul trucks, diggers or shovels, back hoes and cranes. The extraction
of ore requires a different collection of mining apparatus. Ore crushers,
explosives, separators and other devices complete the full complement of
necessary mining equipment. It is vital to remember that personnel are the
fundamental aspect of any mining operation and their safety is paramount.
Essential mining equipment must also include safety supplies, such as hard hats,
ear defenders and respirators, to prevent employees form injuring themselves (or
each other) whilst working in hazardous conditions.
Many criteria need to be considered in selecting the appropriate equipment
for a particular mining operation. The most important factors to consider are
safety, strength and durability, though cost can be a major aspect.
Heavy duty earth moving equipment can be bought direct from specialist
manufacturers who focus on loaders, trucks, drills and scrapers. Other companies
offer leased rebuilt / used mining equipment by major manufacturers. Many mining
equipment manufacturers make ore extraction equipment. Some specialise in air
compressors concentrators and tunnel boring machines, whist others produce
conveyors, crushing plants and hoppers. Specialist underground mining equipment
manufacturers offer an extensive range of pallet handles, tow tractors, belt
drives, radial stackers and power packs. Several manufacturers produce a range
of health and safety products. Some specialise in respirators, hearing
protection, gas detectors, fall protection devices, hard hats and goggles, while
others offer an assortment of specialised flags and lights for use inside mines,
along with rescue equipment for both underground and surface mines.
A mining undertaking can often be large and complex. In order to ensure a
project progresses efficiently, safely and is completed in a timely fashion,
sufficient supplies and equipment must be made constantly available. For speedy
service and extensive choice of products, the Internet is an excellent choice
for the purchase of mining equipment. Many mining equipment manufacturers and
distributors have detailed specifications and photos of their inventory on their
websites and there should be few problems in locating the appropriate tools and
equipment for any mining project. New equipment can be bought directly from its
manufacturer, though it can be a good money saving exercise to peruse the used
and / or refurbished equipment offered by many manufacturers. Other firms
specialise in the hire of mining equipment and dependent on the available
capital, this may be a preferable option to outright purchase.
Mechanical lovers come here to exchange and share ideas
Just to be clear, in spite of advancements in mining machines, mining is
still among the most difficult and hazardous economic activities. It's the
products of this activity which allow the world to function the way it does
today. One can only picture what life could be like minus the products of
mining. Day to day activities gets impeded without the production of natural
minerals and coal; let alone its effects on economic activity. Luxuries like
jewelry also come due to the mining of precious metals.
Machines have developed greatly over the ages. Matter of fact, major
improvements occur every day. New sciences and technologies enable the industry
to develop and supply more for the world. Lots of people are unaware, however,
of the methods and procedures that go into the mining process.
There are two regularly-used excavation procedures applied today: surface and
sub-surface or underground mining. The more widespread of these two is surface
mining seeing that it produces a majority of the world's minerals.
Surface mining, as its name may suggest, is the less difficult of the two.
The process requires the removal of material that is found on the surface
including vegetation or dirt. When necessary, miners dig into the bedrock to
reach the deposits they're aiming towards. This technique utilizes the usage of
one of five further kinds of surface mining. For instance, strip, open-pit,
mountaintop removal, dredging, and high wall mining.
Sub-surface mining, on the other hand, is the exact opposite of surface
mining. This system involves the burrowing of tunnels deep into the earth's
surface to hit the deposit. The products of this kind of practice are then
brought out through the tunnels and shafts created. Unlike surface mining, which
is classified into five forms, sub-surface mining is classified by the type of
access shaft used to remove whatever mineral needs extraction.
People tend to mistake the petroleum industry as being part of the mining
industry, but that isn't the truth. It's easy to confuse the two, considering
the retrieval of oil involves the gathering of a product which is beneath the
surface. Petroleum, having said that, is not excavated like other mineral
deposits. Simply because petroleum is in a liquid state; to retrieve that, it
has to be pumped out.
Innovations in mining equipment like green light laser technology have made
it easier for miners to do their work. Many people are unaware that laser
technology plays a major role in the success of any mining business. Red light
lasers were the standard, but green light lasers are starting to become
extensively used. This is because green light is apparently much stronger than
the red light, and is also visible under direct sunlight.
Characters contrast related with Gold ore processing and coal industry
In Ore crushing plant, gold mining equipment includes Gold ore Crusher ,
sieving, grinding, washing machine etc. It in the primary mill is loaded for the
first time measurement. The mineral mining crusher can the quartz gold rocks in
150 mm or 6-inch pause, then conveyor belt are the crushed ore to the screening
plant goes through screens to the size of the mine material handling. Oversized
rock is sent via conveyor belts to the secondary crushers.
In Gold ore processing
plant, we use devices from pyrite, chalcopyrite, and dignified gold clean.
After it mined out, go first through crushing. Crushing rough in it as ore
primary Crusher Jaw
Crusher is used. Coarse crushing ore with a diameter of more than 10 mm by
secondary granulation process go sieve from fine gold powder that gild in this
crushing, Symons cone
crusher is used. It is loaded into the primary Crusher (Jaw Crusher) for the
initial design. The Mineral Crusher can break the rocks of the gold mine in 150
mm or 6 inches (take PE 750 for an example), then conveyor will carry mine
crushed plant screening, which manages the gold ore through a sieve vibrating to
the size of the material. Oversized stone is sent via conveyor for secondary
crushers. Secondary crushing consists of percussion crusher and cone Crusher.
The major stigma associated with the coal industry today is the abandoned or
'orphan' mines of the early coal mining years. These orphan mines are
systematically being reclaimed under the Surface Mining Act taxes coal producers
at the rate of 35 cents a ton for surface mined coal, 10 cents a ton for lignite
mined coal, and 15 cents a ton for underground mined coal. The tax is paid to
the government and is used to reclaim the orphaned mines.
More than two-thirds of the underground produced coal is extracted by
continuous mining machines in the room and pillar method. The continuous Coal
Mining Equipment contains bits of tungsten on a rotating cylinder. The minor
continues to face coal breaks, and then it passes to a waiting shuttle car which
transports it to the conveyor to be moved to the surface.
It fifty years ago when mining activity the more coal was done manually,
underground mines accounted for 96 percent of product coal each year. Today,
almost 60 per cent is produced from surface mines. Most of the United States
underground mines are located to the East of the Mississippi River, although
there are some in the West, especially in Utah and Colorado.
Learning about the exotisch and innovations of Mining and Mining Machine
Mining is the process of extracting minerals and geological products from the
earth. Miners help collect a lot of elements. These resources are scarce as they
are not grown, agriculturally prepared or artificially produced. Precious
metals, fossil fuel, gemstones, and gold some of these types of materials.
Mining can also help man to get non-renewable power source such as gas, oil, and
perhaps water. The duty of miners can be hard and risky. Using reliable mining
equipment, the job is much easier now.
People of the old period used the soil for some objectives. A good way to
earn a living at the time is through mining. Equipment weren't completely
constructed but many people managed to get a lot of gemstones and various forms
of metals. They use these types of minerals and elements to generate simple
tools for hunting and warfare. Good quality flints within masses of sedimentary
rocks were in-demand in many parts of Europe. Folks utilized these flints as
weapons in the Stone Age.
Ancient Egyptians were one of the first to successfully pick up minerals from
earth. Their particular superior level of civilization made it feasible for them
to generate quality mining tools. They excavated malachite and gold. Malachites
are green gemstones used for ceramics and also as decorations. The Egyptians
began to quarry for other minerals not seen in their soils. They head to Nubia,
a part of Africa. There these people utilized metal instruments as mining
equipment. That's the time when fire-setting was required to extract gold from
ores. This approach involves placing the rock that contain the mineral against
another rock, heat it and douse it with water. This was the most efficient
mining procedure that period.
The Romans also performed an essential part in the history of mining. These
folks were the first ones to use large scale quarrying methods. A good example
of this is actually the use of quantities of water to operate simple machinery
and remove debris. This is actually the birth of hydraulic mining.
The requirement for metal increased significantly within the 1300s. This was
the time when swords, armors, as well as other weapons were in-demand. For that
reason, miners searched for more sources of iron and silver. There was
additionally an increase in the requirement for coins that induced shortage of
silver. Iron, on the other hand, was utilized in developing constructions. With
all the high value of these materials, machineries as well as other mining
equipment grew to be popular in the market.
These devices and equipment were the mothers of the present mining
instruments that we have nowadays. Miners nowadays make use of bulldozers,
explosives along with trucks. More complex type of mining resources includes the
utilization of green light laser being saw guides and machine alignment. With
all these modern-day devices, miners now have a safer and faster process to
break down rocks and even carve out hills. All of these materials are created
and applied using the principles of engineering.
Today, there are five main mining classes. They are coal, metal ore,
non-metallic mineral mining, oil and gas extraction. Oil and gas extraction is
among the largest businesses today.
Mining is one of the earliest mechanized industries. Early engineers applied
steam power to machines designed to move large amounts of earth quickly and
economically. Although the technology improved over the centuries, the
fundamental need to move large amounts of earth and rock has not. Images of lone
prospectors with a pack mule and pick axe is supplanted by massive machines
lifting tons of material and moving earth long distances to processing
facilities in a matter of minutes.
Mining machines must be powerful. Breaking rock and coal seams and impacted
soil requires vast amounts of horsepower and torque. Modern mining machines,
whether hand held or operated by several technicians, are powered by
electricity, diesel or gasoline engines and strong hydraulic systems.
Some earth-moving machines used in wide-open strip-mining operations are
diesel electric, similar to a locomotive. A diesel engine with thousands of
horsepower creates the electricity to power the moving treads, digging booms and
ancillary systems. Some of the machines are so large they house several workers
for shifts days long.
Under the earth both diesel and electric motors power machines used for
boring, digging and removing material. The major factor determining the type of
power is the hazards from flammable or explosive gases in the mines.
Mining Equipment Specialization
Mining equipment is specialized to do one task and do it well. A boom shovel
lifts and moves material a short distance to a waiting truck or crusher.com'
conveyor. A front-end loader moves smaller amounts further distances. Dump
trucks move earth, rock and ore from the site to processing or shipping
facilities.
In the mines machines with large rotating discs fitted with carbide steel
teeth auger away coal. Other equipment quickly transports the coal out of the
mine. Drill operators continuously bore into the seam to place explosive charges
to expand the mine even farther into the Earth. There is little or no
cross-application for this equipment.
Mining Machine Efficiency
Mining by its very nature is a volume business. Miners will move tons of ore
to extract a few ounces of gold. Diamonds have even less of a return for the
amount of rock mined. Coal is brought out of mines by the ton per minute. Moving
this much material means machines must able to hew and lift large loads quickly.
Front-end loaders large enough to carry a car and boom shovels able to lift
small houses means moving more material with one load. The time saved moving
more at once offsets the huge capital expenditure needed to own and operate
these machines.
Mining machines are also subjected to very harsh environments and worked
continuously around the clock. The engineering and construction quality for this
equipment must be the same as for airplanes or laboratory equipment. Down time
for repairs is lost revenue and every minute the machine is working is profit.
Mining machines must be dependable and easily repaired and maintained in
field.

Hongxing has the Magic Weapon for defeating the tailings
Steel slag, slag and fly ash are collectively referred to the three major industrial wastes. However, the utilization of steel slag is much lower than that of slag and fly ash. Steel slag is usually used for packing or for firing cement, overall the utilization is not high. Steel slag contains a certain number of major mineral in cement clinker, which after being crushed and milled by crusher or grinding machinery can be used for cement mixing materials and concrete admixtures. There are still most of the slag heap abandoned in China, which result in the waste of metal and slag resources. Therefore, the crushing and grinding of the steel slag is the vital link, the development technology of the crushing and grinding equipment will directly promote the recycling of slag resources.

Different techniques needed and used for different minerals
Mining is defined as the extraction of mineral and other materials. Mining involves drilling into the earth. Copper, silver, diamond and gold are some of the minerals gotten from mining. There are many different steps in the mining of minerals.
Ore body discovery is the first. Ores are rocks from which metals and minerals are obtained. In order to discover ore, lots of prospecting is performed. Exploration is then carried out to establish the value and extent of the ore.
Resource estimation is the second. The size and grade of ore deposits is approximated at this point. This approximation is then applied in feasibility studies that help establish the economics of the ore deposits. This is important as it provides information on whether there is need for additional investment in engineering and estimation studies. It also helps identify the risks.
It is now that viability studies are carried out. This assists in the evaluation of technical risks as well as how financially viable the mineral mining project is. It is at this stage that mining companies decide whether to continue with the project or abandon it.
When the corporations make the decision to work on the venture, they compute the marketability and profitability of the ore concentrates, the financial requirements to get started and the cost of the infrastructure. Mining starts where the studies divulge that the venture is feasible. Consequently, a processing plant is installed.
Different techniques are used in mining. They are divided into two different excavation types. These are underground and surface mining.
Surface mining is the most common. The bulk of minerals, diamond and silver included are gotten through surface mining. Surface mining is carried out by getting rid of all surface vegetation and rock layers. This is done to reach the ore deposits.
On the contrary, the digging of shafts and tunnels with the aim of reaching the ore is what is involved in underground mining, also referred to as subsurface mining.
The mining of minerals requires the use of heavy machinery. As far as land extraction is concerned, bulldozers, explosives, trucks and drills are essential. Miners and the minerals are transported using trams while lifts carry them in and out of the mines. Huge trucks, shovels and cranes are used for purposes of moving large amounts of ore in surface mining. Machinery to be found in processing plants include roasters, crushers, mils and reactors. They help in the extraction of metals, minerals as well as other vital materials from ores.
The first generation crushers have been created after gradual improvement and promotion of the steam engine and electric motor and other power machinery. In 1806, steam-driven roller crusher appeared. In 1858, an American Black invented jaw crusher which can break rock. In 1878, the U.S. develops gyratory crusher with the continuous broken action. Its production efficiency is higher than older jaw crusher of intermittent broken movements. In 1895, William from United States invented a low energy cost impact crushers and mobile crushers. An American EW Black designed and manufactured the world's first jaw crusher and impact crusher. Its structure is in the form of elbows plate (simple swing) jaw crusher concentrator. As the jaw crusher has a simple structure, easy to manufacture, reliable, easy maintenance, small size and high and other advantages, Jaw Crusher is still widely used in crushing hard, medium hard, soft ore, and various materials such as various minerals, solvents, slag, building stone, marble, etc. Commonly used jaw crusher is about 4 to 6, and sometimes a small jaw crusher can reach 10TPH. Large and medium-sized crusher feed size of up to 1000 ~ 2000mm, its products up to 20 ~ 250mm size. Small crusher and newjaw crusher for fine crushing can produce more fine products. Jaw crusher can be used in both coarse crushing work and medium and fine crushing. The working principle of jaw crusher is Moving jaw plate doing swinging movement periodically, getting close to or leave the fixed jaw plate, thus crush the material in the crushing cavity by extrusion, splitting, bending and impact action. To the 1980 s, Large jaw crusher feed size has reached about 1800 mm whose capacity is about 800TPH. Commonly used jaw crusher has double-elbow type and single-elbow type. With the development of technology, jaw crusher is becoming increasingly advanced and easier to operate. Now jaw crusher becomes the most common mining machinery in many different quarry plants and crushing industries as well as ore beneficiation plantore beneficiation plant. Choosing a good and suitable machine will bring you many greatly benefits.
Generally, whole crushing plant contains primary crusher, secondary crusher and tertiary crusher as well as some auxiliary machines such as vibrating feeder, belt conveyor and vibrating screen.
New times we are emphasising with high-spirited momentum
in recent years China's mining machinery manufacturing momentum of development is very strong, but the prominent problems in technology and strategy is always walk along the old, not radically change for development ideas, and the current mining machinery manufacturing especially at dressing crushing and screening branch line of business, mining machinery enterprise to provide users with complete service to the enterprises. Therefore, in addition to crushing the roll crusher, outside of finely roll crusher, usually a feeder, to ensure that the feeding successive and even, and the length of the feeder with roller length equal, makes the feeding length direction along the roller uniform. In order to ensure the maximum efficiency of hammer crusher, charging must continuously even distribution of the rolls.
We should be regularly check whether the material mouth had blocked phenomenon, and in the motor stopped working to stop before feeding, when material completely dropped, the roll of a power outage, motivation may idling. And roller, the reasonable maintenance and correct crusher of operation, can ensure long-term continuous work, reduce stop time, only normal management and every day to check the normal work of the roll crusher, to prevent failure, and ensure that the work continuously. Therefore, the operator should pay attention to the following items:
(a) Pay attention to all parts, such as the discovery of bolts shall be immediately screw loose;
(b) Before work must first start roll crusher, wait for after normal speed, again to machines feeding, when parking program instead;
(c) Check the material regularly, such as the discovery of a mouth clogged, should be cleared;
(d) Check the vulnerable parts wear degree, always be worn parts; replace
(e) Not make machines produced load, should always be electric instrument;
(f) bear oiling in time, do not make in the place of oil bearing;
(g) Be controlled bearing temperature, may not be higher than the air temperature around 25 to 30 ;
(h) put the plane, chassis activities device should remove dust and material, so as not to roll crusher met and cant broken material, activity in the chassis not bearing mobile, down to produces serious accident.
China's access to the mining machinery production country, consumers and importing countries ranks, but big but not strong. Based on the current situation of the Chinese mine mining machinery factory Hongxing mining machinery through the further deepening the reform and actively adjust the industrial structure and product, the transformation of economic growth mode,Sand washing machine enhance the ability of independent innovation, speed up the high-end mining machinery, mineral processing equipment, crusher equipment and the key parts of the research and development and market development.
Mechanical warfare between mining machinery manufacturers
Mining machinery manufacturing industry is the establishment of an independent state based industrial system, to measure a country's industrial strength is an important symbol.
Broken inside the milling equipment is an important mining machinery components, including jaw crusher, and other broken equipment and Raymond mill, ultrafine powder mill, super mill milling machine dozens of use of diverse equipment, not only in the coal, electricity, chemicals and building materials industries in the deep processing of raw materials play a significant role, but also for railway, highway, water and electricity, the construction of municipal works to provide a high efficient, reliable technical logistical support. Coal, metal and nonmetal mines with the development of more advanced international level of quality, efficient equipment to meet the economic development needs for energy and raw materials of great significance.

The coming year will be the rapid growth of the world's mining machinery industry, the year, especially in China's mining equipment manufacturers, the rare opportunities for development.
Technology has become a prerequisite for the market around, more and more enterprises correct understanding of the technology itself. For the domestic mining machinery manufacturing enterprises in the international market grows, we must first advance in technology and long-term stability. From the mining machinery industry so many years of development and practice, improved technology has always been considered the only choice for healthy development of enterprises. So take a firm 'technology of establishing enterprises,' the road, fully aware that there is no good research can not have a good level of product quality, and continuous introduction of advanced mechanical engineer, and constantly develop new equipment, improving old equipment.
Then one is quality, with good technology, but also good quality, and quality of R & D has a very profound internal relations. Anything can not be achieved overnight, and machinery manufacturing industry is the same reason. The formation of product quality has three main processes: R & D, manufacturing process and use of raw materials. Quality indicators for each stage of acceptance must be strictly controlled, so as to ensure the quality of the product with excellent innate. Hongxing in all aspects of production have developed a corresponding responsibility, to the people, stringent quality checks to ensure that each manufactured devices are optimal. For example, in the iron ore processing line.
Iron ore processing flow chart Iron ore mining processing flow may be the front physical manufacturing process in steeling making course. From the iron ore processing flow chart picture, we are able to start to see the iron ore process flow goes as follow: Raw iron ore is exploded in the iron ore mines firstly. Then vibrating feeder will feed iron ores to the iron ore primary crusher crushing cavity, by which large size raw iron ore will be resized into iron ore sand.
The iron ore sand is transmitted into secondary crushers by belt conveyors evenly and continuously. Then your out let of secondary crusher is carried into tertiary crusher, in which iron ore is going to bewhich is quite fit for the next beneficiation process. Iron ore beneficiation process is used increase the purity to 59% or even more. Iron ore beneficiation process is very important.

How to achieve Out of the mud without dye for machinery industry
As the green movement continues to evolve, more and more people are interested in it. Each would like to make some changes which would be beneficial for the environment. Some people change their vehicles, other people make certain changes to their homes, and some buy only organic products, and so on. The companies and the business are starting to become green as well. They make certain changes as well. Most of the times the changes made by these companies are too simple and to tell you the truth they are insignificant. Especially for heavy industry, the pollution it causes such as ash, tailing, waste water in stone crushing process or sand making process, is very great. Then, how to green business and protect the vironment efficiently? Now, there are some strategies for your reference (about 10 rules).
1. Recycle!
This one is a no-brainer. If your company isnt already recycling, its way past time to make the leap. Its easy, and most cities worldwide have recycling pick-up available, if not already mandatory. Just put out some color coded containers for plastics, paper and metal, and inform employees of the new recycling policy. Many tailings left through the jaw crusher or impact crusher can be reused again reasonably.
2. Electronic Documents
Now that youre recycling your office paper, why not just get rid of it all together? Email is obviously far greener than snail mail, and faster too! Fax modems now allow you to fax documents directly from the computer, and electronic signature services like EchoSign.com can even facilitate the signing and storage of legal documents without paper!
3. Heating and Cooling
Raising the thermostat just a few degrees in the summer and lowering it a few degrees in the winter can save 10 to 20 percent on heating and cooling costs annually. Sure, there are expensive upgrades to more efficient office and shop cooling systems, but adding an extra layer in the winter and allowing short sleeve shirts and khaki shorts during the summer can be just as effective!
4. Lighting
Incandescent light bulbs are a thing of the past, and embracing LED and CFL lighting will not only save you money in the long run, but conserve massive amounts of energy as well. Also be sure to take advantage of natural sunlight, dimming lights or turning them off when window light is abundant. Plus, dont forget to turn the lights off before heading home at night!
5. Reduce Water Waste
Electronic faucets and low-water toilets can reduce water waste drastically, but can be an expensive upgrade. Consider instead a little common sense extended to your employees, such as notes saying, turn the faucet completely off, or only run the dishwasher when full. Add sealed plastic containers filled with rocks to toilet reservoirs to limit water waste per flush.
6. Used or Refurbished Office Furniture and Décor
Buying second-hand office furniture and decorations can save tons of cash while creating a funky, unique workspace. Several warehouse distributors specialize in used office furniturelike Office Furniture Now! In Austin, Texasand eco-friendly design and build firms are popping up all over the world, which specifically utilize refurbished and renewable materials.
7. Shut Off Equipment
Leaving office equipment running when no ones in the office is a huge drain on energy, and could cost you thousands every year in electricity bills. Simply delegate to employees to turn off or unplug equipment before leaving for the night. There are even smart power strips that can automatically shut down equipment.
8. Teleconferencing
Think about how much money, time and fuel is wasted traveling via plane, train and automobile just to hold a meeting in another city. These days, thanks to services like GoToMeeting and Ciscos TelePresence, theres no need to travel. You can hold online meetings with various people from various locations thanks to video conferencing.
9. Telecommuting
Lets face it, most jobs these days have employees staring at a computer screen for hours on end. Why not let them do it in the comfort of their own home? It frees up office space, and with tools like email, Skype, and web chat, you can still manage workflow. Studies reveal that telecommuting saves businesses immense amounts of money. Employee time and paychecks also go further, since gasoline purchases are reduced and employees dont waste personal time preparing for and driving to work.
10. Green Sourcing
From paper to staples, writing utensils to printer ink, even vending machine snacks and beverages; all these items come from somewhere and are made of something. Is it recycled and/or recyclable? Is it organic and/or local? Is it natural or synthetic? These are all questions you should consider when sourcing office goods. With a little searching, you can likely find eco-conscious solutions to almost all of your supply needs.
These points are not obtained at once, as I said it takes months before a company can receive them. Usually the company must accomplish certain things before it can receive them. In fact, telecommuting may be the single greatest way to save businesses money while bolstering national economies and reducing energy consumption. The Telework Research Network claims that on average, half-time telecommuting saves companies over $10,000 per year per telecommuter! These studies also reveal a 25 to 40 percent increase in productivity, which could equate to a $200 billion yearly increase in productivity in the U.S. alone.

China manufacturing industry and enterprises adhere to the times
As we know, America is a powerful country on the earth with advanced science
and technology and abundant finance. Compared with America, it seems like that
China cann't compete with it. But today I'm turning that question around in
manufacturing industry. What doesn't get enough attention in today's discussions
about America's economic competitiveness is that the U.S. remains a robust
manufacturing power, despite what is going on in China.
What doesn't get enough attention in today's discussions about America's
economic competitiveness is that the U.S. remains a robust manufacturing power,
despite what is going on in China. What's more, American manufacturing is
becoming more productive. In 2009, productivity in U.S. manufacturing increased
by 7.7%, more than any other country followed by the Bureau of Labor
Statistics.
Shopping through your local Target, you're going to see a lot of Made in
China labels on things like clothing or electronics. The U.S. tends to make
stuff that requires more technology and engineering know-how, like planes,
semiconductors and machinery. But the U.S. still is very competitive in the
types of products that demand a high level of technology, engineering and
capital to produce. In such industries, wages don't matter quite as much, and
the U.S. can capitalize on its clear advantage over emerging markets like China
in expertise, technology and innovation. That's why the U.S. sells Boeing
aircraft to China, and the Chinese sell blue jeans to Americans. And it is here
where we find the big challenge for China as a manufacturer going forward. A big
part of Chinese manufacturing is the simple assembly of products designed
elsewhere with components produced elsewhere, which means China is some cases is
not adding very much value to the products it produces in factories.
More balanced growth. Whenever economists talk about China, they focus on the
need to rebalance. That means China is too dependent on exports and investment
for its growth, and needs to increase the role of private consumption to make
its growth more balanced. More rational companies and banks. Under China's
state capitalism, the state-owned banking system and big companies can easily
fall victim to government mandates and policy priorities, leading to problems
like asset bubbles, excess capacity and a weakened financial system.Democracy.
Few things annoy me more than having to sit through mindless praise of China's
authoritarian political system, especially from Westerners who don't live under
one. Many businessmen believe that authoritarianism in China has been a
necessary factor behind the economy's rapid growth. And we can see from the
development situation that China mining machinery industry is expanding fastly
and exports in crushers, vibrating
screens, impact
crushers and other machines increase rapidly.
That's especially because of the direction in which manufacturing is
headed.Inexpensive manufacturing labor will not be a factor for long with the
acceleration of technology in manufacturing processes. Our manufacturing is
moving to a technology driven operation rather than a labor one. The skills
required by manufacturing are changing. It won't be long until IBM's Watson will
be directing the manufacturing with robots doing the work.
In other words, manufacturing competitiveness will increasingly be based on
American, not Chinese, advantages.So America's manufacturing future will depend
on continued innovation, and the future of the American manufacturing worker
will depend on improved education to support that innovation. Such advancement
is imperative. China won't be far behind.
Measures for high efficiency and low consumption when using ball mills
Ball mill
grinding mill efficiency and productivity improvement, efficiency, intermittent
ball mill, machinery, ball mill grinding efficiency and yield of the price
increase is a common fine grinding mill machinery spare parts, in the mineral
processing industry, building materials and chemicals have applications in the
field. As a general-function equipment, it's important to know how to improve
ball mill's productivity.
A ball mill is a type of grinder used to grind materials into extremely fine
powder for use in mineral dressing processes, paints, pyrotechnics, and
ceramics. Aside from common ball
mills there is a second type of ball mill called Planetary Ball Mill.
Planetary ball mills are smaller than common ball mills and mainly used in
laboratories for grinding sample material down to very small sizes.
Generally speaking, there are all together three shortcuts to increase the
productivity of ball mill:
(1) Add Fine crushing machine before ball mill;
(2) Improve milling system;
(3) Add high-efficient powder concentrator
Three methods mentioned above, any one kind of ball mill can greatly improve
yields.
Of way, if conditions permit, the factory, then supporting the use ofthe
above 3 methods, the effect is the most ultimate, which is grinding system at
home and abroad in recent years the trend. Three relationships: the premise of
grinding before crushing, grinding powder to make sure that after the election,
the fundamental transformation of the roller mill. Milling is premise with fine
crushing, powder concentrator after milling guarantees its quality. Fine
crushing makes material size decrease a lot, thus lowering milling load; The
increased efficiency of powder concentrator has its advantage: timely and
largely selection of end product powder will reduce the frequency of powder
remilling. If the efficiency of milling system is low, milling productivity as
well as cement quality will be highly affected.
As an entrepreneur the theory must be known well and mastered
It's known that crushers have stable place in heavy industry. From
traditional crushers to advanced crushers, the technology and quality are better
and better, but also the policies and theories are innovated. In old days, in
the saling process, there are simple tips: making the price, communicating with
clients, bargaining, coming to the deal. In the process, there is not some
attention on clients' demands. That is to say that what we have what we sell.
But in foreign crushing machinery compaies, they are closer to their clients,
and pay attention to clients' demands and feelings. So there are more and more
crusher brands from abroad set foot in China market.
Theory of 4C posted by American marketing specialist, Professor Lanteborn, in
1990, takes client's demand as the guide and resets the four basic factors of
marketing management: Consumer, Cost, Convenience and Communication. Zhengzhou
Hongxing puts consumer's demand in the first place according to the Theory of
4C; and next decrease the purchasing cost for client; and then pays sufficient
attention to onvenience when consumer make a purchase; at last, communicate
efficiently around the client to reach the deal.
Theory of 4C takes consumer's feelings seriously and takes market demand as
the direction, which is easier to be accepted by the market. Crusher company
shall take effort to use 4C. At frist, to value crusher consumer's product
experiences. Secondly, to consider client's feelings. Don't let client spend
much time and cost in finding and purchasing. Thirdly, as to convenience, we
think everyone knows how to do it. The last but not least is communication. To
learn client's demands on crusher collocation, application scale, consumption
level and so on, and then to give consumer best suggestions.
To sum up, marketing management is the same as fighting. Just as the ancient
Chinese philosophical book The Art of War concludes, if you know yourself and
your enemy, you'll never lose a battle. Theory is just as reference, and
practice is the best channel to communicat with all types of consumers, to learn
bout all types of demands, and finally to come into successful deals.
We company are specializing in producing series of mining machines. There are
four series main equipment: stone crushing equipmet, sand making equipmet,
powder making machine and ore dressing machine. We hold 3 First tenent to do our
business: ' Quality comes the first; Service comes the first; Clients comes the
first'.
With the popularity of social media it's important to create Brand Effect
With the development of technology, crushers have made bright progress.
Especially after the 90s, production and sales quantity of crushers increase
rapidly. In addition, according to the related analysis, the current global
annual number of broken materials has achieved as much as 10 billion tons, but
in China each year we only crush about 1.8 billion in a variety of materials,
including that iron ore is about 240 million t, non-ferrous metal ores more than
100 million, non-metallic minerals 230 million t, chemical minerals 030 million
t, cement about 400 million t, the building limestone 470 million t, the power
consumption 250 million kW-h, steel consumption of about 2.5 million t. This
rising situation must push crusher industry and crusher component industry to a
new development time.
Recent years, in order to promote the competitive strength, Henan Hongxing
Mining Machinery Company gives a series of innovations and policies. The
advanced technologies have been introduced from America, Germany, Japan and
Australia, which established the international advanced production line,
first-class modern testing base as well as research centers of sand maker, mill and
mine-selecting equipment. Scientific management, advanced processing technology
and innovative manufacturing theory make the company become the mining machinery
manufacturing and exporting base in China.
We have been awarded the Civilized Enterprise Key Enterprise Enterprise
with Standard Quality and Enterprise with Honesty and Credit Standing. Many
Hongxing machines are exported into India, Maxico and South Africa, and they are
popularized at home and abroad.
How to tackle the unstable price of coal slime dryers
As we all know, Construction machinery industry has a significant industrial
characteristics, the market demand for construction machinery affected by the
macroeconomic impact of large, especially with national infrastructure projects
closely related to the construction of facilities. Here, we will analyze two
aspects of construction machinery industry, market characteristics.
Recently, there are more and more coal slime dryers in the market. Because of
market demand, the price is always not stable, and the nation has no fixed rules
on it. For this condition, we company give some conclusions:
1) The effect factor depends on the machinery compay's scale. Big company
makes the price according to the quantity, so the price is relatively low.
2) The second factor is decided by the price of steel or other raw materials.
For example, this year's steel price keeps rising, so the price of coal slime
dryer is higher than that in 2009. However, the price of steel in the first half
year of 2009 was very low, on the contrast, the price of the equipment was lower
than usual.
3) Product quality is also the important factor. The machine in good quality
whose price is higher, because the consumption on materials and production time
is higher.
The persistent operating theory of Hongxing is: the development way depends
on the concept and the good product comes out of the good faith. We have been
awarded the Civilized Enterprise Key Enterprise Enterprise with Standard
Quality and Enterprise with Honesty and Credit Standing. And Hongxing Brand
is a 'China Famous Brand' for reliable and stable quality. We firmly believe
that we can get sincere repayment with our sincere dedication.
Why is ore broken? Why don't we choose ore in small particle size in
industrial production directly? This is actually a very good idea. We can fikd
ore in standard particle size directly that is free from crushing processes and
put the ore into production. With the way, it can save a mount of time, money
and labor force. However, the ides is not realistic.
Ore exploited from the mining of mineral is called raw ore or crude ore.
Crude ore consists of mineral raw ores and the gangue. The largest particle size
of crude ore come out from open mine mining is in commonly 200 to 1300 mm, while
that come out from underground ore mining is in commonly 200 to 600 mm. these
undressed ore can not directly used in the industry application, but it must
pass a broken and grinding work to make the particle size meet the prescribed
requirements. And now in the general cement plant, quarry plant or
construction base, the needed material has special requirements. The stone just
developed out of mining colony is not in substandard grain size and eligible
type, and some even has impurities mixed. So the stone must be gone through a
series of processes, and after that the stone can be chosen to use.
A crusher is a machine designed to reduce large rocks into smaller rocks,
gravel, or rock dust. Crushers may be used to reduce the size, or change the
form, of waste materials so they can be more easily disposed of or recycled, or
to reduce the size of a solid mix of raw materials (as in rock ore), so that
pieces of different composition can be differentiated. Crushing is the process
of transferring a force amplified by mechanical advantage through a material
made of molecules that bond together more strongly, and resist deformation more,
than those in the material being crushed do.
In industry, crushers are machines which use a metal surface to break or
compress materials. Mining operations use crushers, commonly classified by the
degree to which they fragment the starting material, with primary and secondary
crushers handling coarse materials, and tertiary and quaternary crushers
reducing ore particles to finer gradations. Each crusher is designed to work
with a certain maximum size of raw material, and often delivers its output to a
screening machine which sorts and directs the product for further processing. In
operation, the raw material (of various sizes) is usually delivered to the
primary crusher's hopper by dump trucks, excavators or wheeled front-end
loaders. A feeder device such as an apron feeder, conveyor or vibrating grid
controls the rate at which this material enters the crusher, and often contains
a preliminary screening device which allows smaller material to bypass the
crusher itself, thus improving efficiency. Primary crushing reduces the large
pieces to a size which can be handled by the downstream machinery.
Crusher is the bridge between ore and arenaceous stone. The ore crushed can
meet demands of all clients. According to the fixed standard, it can be put into
various production lines.
Collections of main crushing machines used in mining industry
Crusher is a kind of crushing machinery. According to different functions, it
can be divided into medical crusher and mining crusher. Medical crushers are
used for calculous breaking, to avoid the various risks during surgery. And many
different crushers are used in mining industry. Here some types of crushers are
introduced.
Mining crushers are commonly known as crushers, which are mainly used for
various types of stone crushing. According to different crushing principles and
particle sizes, they can be divided into many different types.
Crusher is widely used in mining, smelting, building materials, road,
railway, water conservancy, chemical and many other industries. The currently
used crushing machines are jaw
crusher, impact crusher,
air classifier mill, hammer crusher, roll
crusher, compound crusher, etc. A brief introduction to some of them is as
follow.
Jaw crusher. It uses two jaw plates to squeeze and bend the materials with
different hardness in a variety of pieces. It is the first choice for first
class crush. Jaw crusher is of the characteristics of high crushing ratio,
simple structure, reliable operation, easy maintenance, economic operating costs
and so on. So it is widely used in mining, smelting, building material, highway,
railway, water conservancy, chemical and many other sectors.
Cone crusher, which is of
small discharge opening, so that it requires more strict particle layout size.
It is widely used in metal and nonmetal mining, cement, sand and metallurgical
industries, applied in the crushing of various minerals and rocks, such as iron
ore, nonferrous metal ores, granite, limestone, quartzite, sandstone, pebbles
and so on.
Impact Crusher has a simple structure. It is of large crushing ratio, low
energy consumption, high output and light weight. The finished product was
broken into cubic shape. It is used in a variety of industries, like ore
crushing, railway, highway, energy, cement, chemical, construction and so
on.
Hammer crusher. This crusher is of high capacity and crushing ratio. The
particle size with it is uniform. It is the major equipment used in metallurgy,
building materials, chemicals and industry for the crushing of limestone, coal
or other medium hardness brittle materials.
In general, there are five methods for stone crushing. First, squeezing.
Using squeezing pressure of the two crushing plates to break materials. Second,
splitting. It breaks materials into pieces with the force when the sharp teeth
being split into the material. With the centralized power, partial fragmentation
can be occurred. Third, broken off. Material break itself between the crush
plates as if a beam loading concentrated power. Fourth, two plates do the
relative motion at materials, so that shear stress is applied. Fifth, the use of
impact force. The instantaneous force act on the ore. For example, impact
crusher is mainly uses the impact crushing force.
For fine screen advanced design and technology are injected in Vibrating Screen
Henan Hongxing which introduced its YK series screening machine in 2007,
recently developed a newly designed drive system for this product line, allowing
more amplitude and rotary speed combinations. This new feature, according to the
company, allows small cut sizes to be achieved and also offers the capability of
handling difficult classifying jobs with large cut sizes. In addition, the
machines now feature a new wear-protection system that reduces the downtime
needed to replace worn elements. The company also notes that although the
earlier vibrating screen
machines had a standard deck width of 2.40 m, the introduction of a modular
construction system has since enabled fabrication of machines with screen decks
up to 4.20 m wide.
You'll always make the right choice when selecting the Hongxing linear
vibrating screens for wet and dry screening applications and where gentle and
especially exact screening is required. Its minimum height is yet another
important advantage for plant operators. Directional vibration is generated by
two counter-moving unbalance weights. We offer three different drive types,
dependent on the machine weight, size and application:Unbalanced motors,
Twin-shaft drive, Exciter drive.
Our wide range of dewatering screens and vibrating feeders are also part
of our linear vibrating machines line-up.
Effects from depression and upsurge of iron ore on Mining Machinery Industry
Iron ore is one of the main raw material in steel production, and its
development status has a very great impact on steel development. While the
development of steel can promote development of iron ore. Chine is a big country
to produce steel, and also has great consumption power on iron ore. Along with
the rapid economic development in China, the demand for iron ore increases in a
high degree.
'In the September-October period demand usually picks up and we expect steel
output rates to accelerate, which is positive for iron ore demand,' Commonwealth
Bank of Australia said in a report.
Shanghai, Tianjin and Beijing are export-oriented cities, and steel usage
amount has reached the level in developed countries such as South Korea, but
really attractive is that the demands of China's inland provinces and cities
just beginsto rise. At present, China steel consumption per capita in the
Midwest is even less than half of the coastal areas. In order to narrow the gap
between the rich and the poor, the Chinese government adds to the construction
of infrastructure investment in the west region, and the policy will also pull
steel demand. China will continue to drive global demand for iron ore for a
period of in future, and also open up the iron ore market in the West.
Of course, China demand of iron ore has depressing period, but in the long
run according to current situation, it won't stop the development of future iron
ore market. Yesterday's drop was a knee-jerk reaction to the move. I think by
now many in China are so used to these things they have learned to work with it.
Outlook for steel demand is still bright,' said an iron ore trader in Shanghai,
'There's absolutely no weakening in the market. Demand is strong, especially for
low-grade ore, which brings down mills' costs dramatically.'
The expansion of iron ore industry in the western market needs promotion of
the machinery industry. In the mining exploitation, utilization and processing,
crusher, sand machine, finely machine, milling machine, crushing equipment are
necessary in the machinery industry, and also donate the dominant position. The
series of equipment processes raw ore into finished materials required by
mutiple industry. So the iron ore market development does not only drive the
machinery industry development, but also lead the development of the crushing
equipment like crushers.
Nowadays, the prosperity of one country depends on rising technology that can
not only save energy and take use of energy to the best, but also protect
environment. At present, the demand for iron ore and other mineral materials
push the expansion of mining machinery industry such as crushers gradually. The
development is embodied in both market and thchnology. Thus, the mining
machinery industry can go forward to the further and keep sustainable
developmemt.
Drying technology is one multi-industry and interdisciplinary technology with
a broad service scale. And now, it is also in the circle of science. Facing to
so many industries, various materials, different demands, our countrie's drying
technology is short of science theories and design methods, however, the main
way is to depend on experiences and small-scale experient information. Because
of the old ways, the drying equipment doesn't work efficiently. Therefore, our
country's machinery factories have to make sufficient and convictive trials
before establishing industrial drying machine.
After ore dressing process, the final mine or the ore concentrate would be
very wet. And before the next working procedure coming, the water in the mine
would be removed. So, the Dryer is necessary. In concentrate drying, Hongxing's
engineers have undertaken extensive development work into the drying
requirements of mineral concentrates. They have applied an innovative and
inventive flair combined with a detailed understanding of handling and particle
integrity characteristics for drying this range of products. A multitude of
successful test and development work, together with evaluation of the effects on
smelting, have culminated in cost-effective, efficient nickel copper iron
chrome sulfur based and similar concentrate drying systems that work. We
produce two type of dryer.
1) Indirect Heat Transfer Dryer:
The indirect heat transfer dryer made by our company is mainly used in
building materials, chemical industry cement plant for drying of
limestone slag, driving device, supporting device and sealing ring. The dryer
has advantages of reasonable structure, high efficiency, low energy consumption
and convenient for transportation. Indirect dryers employ similar principles of
operation to direct dryers. However the fundamental difference is that the
method of heat transfer is predominantly by conduction as opposed to convection.
These units are sometimes referred to as contact dryers.
Dryer(Drying Machine) is used for drying materials with a certain humidity or
granularity in milling of ores, building materials, metallurgy and chemical
industry. Gyro drying machinery has a strong adaptability of materials and it
can dry various materials. The operation is very simple and liable. For this
reason, it is used widely.
If you are interested in the Dryer by us, please Contact us or visit the
website of the company for relevant prices and detailed technical parameters and
specifications etc. We all will assure you of our best service at all
time!
