Rising RMB exchange rate makes great impact on mining machinery
Problem on RMB exchange rate has been advertized in large scale. Many western
countries put pressures on China around RMB exchange rate. Especially, the issue
of Sino-US trade surplus has made the RMB exchange a much more important topic
than ever. Since the Chinese government changed its exchange rete regime on July
21st, 2005, studies on further reform steps have become booming. Nevertheless,
China government state many times that they will keep RMB exchange rate stable.
Of course, with the appreciation of RMB, it brings many significant influence on
various industries such as on inflation, especially on its persistence, hence
the persistence of shocks to price stability. Henan Hongxing is specializing in
exporter of mining machinery equipment. Views on this point, there are some
analyses and predictions.
The appreciation of RMB will affect exports, mining machinery include. We can
give an simple example. Supposing that Henan Hongxing Machinery Co., Ltd export
a new type sand making machine
to South Africa, and both sides agree with paying by U.S. dollars, while the
equipment price is $25000. If before the appreciation of RMB, the exchange rate
is like this $1 = 8.3 yuan RMB, so we can get 207500 yuan RMB from banks; now
the RMB exchange rate is $1 = 7.9 yuan RMB. So after appreciation we can only
get 197500 yuan from banks. Thus vested interest will reduce greatly, even will
make the losses not to keep the exports. As to mining machinery, other exporting
enterprises meet the same problems and no exception.
Present RMB exchange rate has raised to $1 = 6.6415 yuan, which breaks
through the gate of 6.65 to creat a new top. And also, some specialists predict
that the pressure of RMB appreciation is still great and it signs the unstable
RMB exchange rate.Under this situation, how to deal with the trend for mining
machinery industry? Hongxing company holds the view that mining machinery
exporters shall change the main business point and pay more attention on
domestic markets. With the development of science and technology, demands on
domestic markets are more and more, which will also take great chances and
profits. For example, foreign countries has raise the price of steel that
affects the domestic crusher industry. Therefore, many enterprises are trying to
change the strategies to avoid the attack and loss. At present, China
construction industry is prosperous. However, in construction process, mining
machinery is essential. For example, jaw crusher, grinding
equipment are used widely. So in the trend of RMB influctuation, it's efficient
and wise to grasp domestic markets of mining machinery industry.
Important circle in heavy industry task: latter maintenance of cone crushers
In task of heavy mining machinery, it's important for equipment model
selection and operation. However, later period maintenance is similarly
significant. Proper and timely maintenance can extend the life of one equipment.
Here, taking cone crushers as
the example.
A. the materials must be in the middle of the distributor, see diagram 14. it
is not allowed to put the materials into the crushing chamber directly, because
it will make the crusher overloaded and the liner plate will be abraded
unevenly. Correct feeding conditions :
a. the materials are distributed equally to the crushing chamber.
b. The quantity of materials should not higher than the mortar.
B. the max feeding size should not equal to the feed opening, (the max
feeding size=85% of the feed opening) otherwise, it will lead to:
a. the capacity is low
b. some spare parts will be damaged.
c. crusher is not allowed to start in overload condition in case of
accident.
d. when stop the crusher, stop the feeder first. After the materials are all
discharged out, stop the crusher.
e. the locking system and hydraulic station should be checked often to avoid
problems.
Capacity of the crusher
Capacity is subject to feeding method, material size, size of final product,
material nature, temperature, etc. the range is wide. The capacity is under
certain conditions.
Change of mortar
There are u-shaped bolts on the adjusting ring. Fill zinc alloy into the
space. When installing or changing the mortar, after 6-8 hours' operation, check
the fastening conditions and screw the U-shaped bolts again.
Change of the crusher inner wall
The Cone crusher inner wall
is fixed to the cone crusher body through a cone end. There is zinc alloy
between them. When installing or changing the inner wall, after 6-8 hours'
operation, check the fastening conditions. If there is loose, fasten it.
Mesh of gears
The friction of round plate changes the gap between gears. To make the gears
properly meshed, clients are required to put a mat on the bottom cover. The
thickness of the mat should equal to the friction of the round plate.
Bowl-shaped bearing and sealing device
When installing the bowl-shaped bearing, make sure the oil seal is not
damaged by the steel cable.
When assembly, scrape the spherical surface to ensure the space between
crushing cone and the spherical surface is kept within 0.35-0.5mm.
The bowl-shaped tile is fixed to the bowl-shaped bearing support through lock
pins to prevent the tile rotate in circle.
The bowl-shaped bearing support and the frame are fixed together by lock. If
there is space between the support and the frame, deal with it immediately.
The cylinder liner and the frame is the third transient assembly.
To avoid the liner rotating, the upper part of liner is filled with zinc
alloy. When changing new liner, make sure it is according to the practical size
because the after long time's operation and assembly, some changes may happen to
the crusher. If the space is too large, the liner will be broken.
Conic liner
The cone cover and the eccentric shaft should wring each other. Fill in some
zinc alloy to stop the cover rotating. The space should be full of zinc alloy.
The cover may change its shape due to the hot zinc alloy, so check the size of
d1, d2 and B of a new cover. If it is incorrect, correct it. When making spare
parts, make sure it is fit for the practical size of the inner diameter of
eccentric shell.
Springs
A. The function of springs is: when some uncrushed materials enter the
crusher, they will prevent crusher from damaging. Therefore, the pressure of the
springs and the crusher is corresponding to each other. If the crusher is in
good condition, the spring is stable; only when uncrushed materials enter the
machine will the springs be pressed.
B. If the upper part of crusher vibrates, clients are required to check the
machine carefully and solve the problem. If pressing the springs incorrectly,
some parts may be damaged, because pressing the spring will increase the
pressure of the crusher.
The reason why the upper parts of crusher vibrate is:
a. feeding unevenly or overfeeding
b. there are many small lump materials in the raw materials or the humidity
is too high
c. the discharge opening is too small.
The outer rotation parts of the crusher should be protected with cover which
is prepared by clients.
Sand maker of HXJQ installs and runs smoothly and easily
Hongxing impact
crushers are the heavy type equipment, and also called sand making machines.
The installation and operation both have fixed ruels and instructions. Generally
speaking, if you install and use the sand making euqipment according to the
following instructions, the equipment using life, product quality and personal
safety can be guaranteed. OK, let's list the attentions when installing and
operating a sand making machine.
A. When installation, adjust the horizontal position. The machine must have
the basic conditions:
1) feeding materials sequent .
2) large pieces of materials can return back to the machine.
3) there is the lifting equipment upon the machine and it can lift the
machine conveniently.
4) there is enough space to check up on one side of crusher.
1. Preparation works before start-up Sand making machine has a trial run for
4 hours in factory and all parts are in order. However, you must check up the
machine again before start-up.
1) Check up turntable is balanceable or not, that is, wearing parts is
installed in a whole set or not .
2) The position of triangle belt is suitable or not, that is, strain is
suitable or not.
3) All parts are connected steadily or not, and screws are fastened or not
1-4 Check up if there is a tool or sundries in the machine. Close the inspection
door and plug into safety bolt. Don't open inspection door when operation. 1-5
Check up the running direction of engine and turntable is correct or not:
anticlockwise rotation from the feeding port 1-6 Check up lubrication is enough
or not.
2. Start-up without load
1) Ammeter is working or not .
2) The control system: Y/' reducing the pressure start-up; Y/' time transfer
relay should be adjusted as 50S or so.
3) Start-up of double electrical machine: Stand-alone start-up and Two engine
start-up. You can choose the start-up according to the power of electric
network.
3. Start-up with load.
1) Feed the materials after the machine have a successful trial run without
load and the running of engine becomes ' type.
2) Max Feed Grain Size must be executed strictly according to
instruction.
3) You'd better put in the materials less than 5 mm at the beginning of
start-up ( at least in half a minute) so that it can form protection layer in
the machine.
4) When you feed the materials at the beginning, there will be a 30-60
seconds imbalance the machine. However, you mustn't stop the machine at once and
that feed more materials until the vibration disappears. If there is violent
shock and abnormal noise, you should stop the machine to check up carefully.
5) You'd better add magnetic
separator beside feeding advice for fear that iron damages the machine
chamber in the machine.
6) Max electric current value is not exceed rated current one of running
motor when feeding the materials. If the humidity of raw materials is too high,
it maybe block the feed opening of central flow and overflow port of scattered
flow and influence electric current value. The electric current value is too
high and can't be lower because the overflow port of scattered flow is blocked.
Contrarily, the feed opening of central flow is blocked. You must stop the
machine to clean up all feed openings and then work sequentially.
7) Dual drive motor must regulate and bring the strain of two groups of
triangle belts into harmony. Look into two groups of electric current value of
motor is accord or not.
4. Stop the machine
1) You must stop feeding the materials before stopping the machine.
2) The ammeter should be without load before stopping the machine.
In China Mining Industry and Economy Development Hongxing gives a big hand
AS a pillar industry in China, mining machinery industry plays an important
role in economic construction and social development. It is also a great
protection of the national economy's healthy and rapid development.As
construction materials processing equipment, mining machinery and
miningequipment provide a large number of basic industrial products and
energy.Therefore, mining machinery manufacturing industry can become the
nationalfoundation for the establishment of an independent industrial system,
and animportant symbol to measure a country's industrial strength.
The crushing and grinding equipment are the most importantcomponents in the
mining machinery. Crusher is widely used in mining industryand has vast
potential market in the world. In the past years, crusher hasimproved and
innovated on the basis of assimilating and absorbing the importedtechnologies.
Mining Crusher ismainly used for large-scale mining, ore crushing process, which
for the gravelor broken stone, generally refers to the original ore after
blasting mountainsis processed into the finished size to meet demand. According
to ore materialfeeding size and its particle size, proper crusher was chosen and
being crushedthe raw ore.
For the mining equipment manufacturers, 2011 is a morecompetitive year, and
only the stronger can survive. Only those enterpriseswith high industry
perspective, first-class R & D team and technicalservice personnel can
survive. Henan Hongxing Mining Machinery Co.,Ltd makes his declaration to the
whole market with his high-tech products: HXJQ will live up to expectations,
continue to maintain industry-leading products and technologies for domestic and
international mining, chemical industry, metallurgy, construction industry, and
provide first-class products and best qualityservice.
The world's ability to support its population is sustained by the many
minerals provided by mining. Virtually all of mankind's material needs must be
dug from the earth, grown in the soil, or taken from the sea. According to
different types of minerals, their useage are different. There are serval main
minerals and their important uses:
·Copper: wiring for motors, telephones, televisions, computers, home
appliances, functional/decorative hardware, coins.
·Lithium: lubricating grease, high efficiency batteries, ceramics/glass.
·Magnesite: lining kilns/boilers, sugar, additive in cattle feed.
·Barite: oil well drilling mud, bowling balls, rubber, medicines.
·Gypsum: main ingredient in wallboard (sheetrock) and used as a soil
conditioner.
·Sand, Gravel and other Aggregates: roadways, cement, cinder blocks, golf
course sand traps.
·Silica sand: window panes, fiber optics, jars and bottles.
·Zinc: plating, rust inhibitors, paint.
In order to obtain excellent and proper minerals for our demands, mining
equipment come out, such as jaw
crusher, energy saving cone ball mill, magnetic separator, spiral chute
etc.
Role and function of big contributor for Construction Industry
There are different types of construction that can be performed depending on
what needs to be fixed or built in society. For instance one major type of
construction is heavy construction. Heavy construction is the type of work that
occurs when infrastructure is added to an already built up environment, such as
building a highway. Those who own heavy construction projects are typically
national or local level government agencies that deal with large contracts that
last quite a length of time.
Heavy construction projects are usually done in the best interest of the
public to service them better. Of course, it is hard to agree with this when
you're stuck in traffic while the roads or the sewers beneath them are being
replaced, but indeed the end result has us in mind. That being said, not every
heavy construction project is undertaken by the government. Some large, private
corporations, such as power companies, harbors, railroads, mines and golf
courses, are also involved. These private companies, among others, undertake
heavy construction in order to create dams, railways, massive earthwork
projects, etc.
Some developments that are considered heavy construction projects include:
buildings, parks, playgrounds, apartments, stadiums, factories, malls.
The most important part of heavy construction that makes it successful is the
equipment that is used. Heavy construction equipment is essential to the
project, because without it, even the basic construction work could never be
completed. They are typically quite large, and are created specifically for one
or two different uses. The primary equipment used for heavy construction
includes but is not limited to: bulldozers, cranes, well drilling machinery,
earthmoving equipment, loaders, draglines, cable plows, scrapers, generators,
rollers, light towers, etc.
Each piece of heavy construction equipment plays an important role in the
project. For instance, as far as groundwork is concerned, heavy rollers are
used. Heavy rollers set up the project and find the base. They are then used to
raise and drag tons of stones and iron from one place to the next.
The biggest problem that often occurs with heavy construction is the cost of
building. Heavy equipment is quite expensive, and the people needed to work
these machines and tools need to have the skill and experience in order to
handle them. That being the case, many companies make the decision to rent or
lease heavy equipment, sometimes even with or without the operators.
Unfortunately, because operators need to have both the skill and knowledge to
work the equipment, they have become practically as indispensable as the heavy
equipment. This can sometimes cause problems for companies who require heavy
construction projects. To beat this problem, some companies hire people and then
pay for their training, as opposed to trying to find someone who already has the
training and is therefore going to request a much higher salary.
Despite certain problems, and expenses, most heavy construction projects are
completed. The result of a heavy construction project is usually something that
many people can benefit from and enjoy.
The mining industry in many developing and third world countries has, over
the last ten to fifteen years, undergone a great growth period. New methods of
finding minerals have been discovered and it has caused old mines to be
re-opened and new mines to begin. Mining involves a fairly simple principle of
extracting minerals from the earth and refining this raw material to finish with
an end product. These products, such as gold, silver, iron ore, copper or lead,
are all very valuable in our world at present. The gold prices today are at
record highs. This leads to many new mine companies starting up or old ones to
go through rapid growth periods.
The primitive mining methods existent thousands of years ago, have now been
replaced by new methods involving machines. People used to dig away at a
mountain by hand or by use of small hand implements. Then came the use of horses
and animals as power, which made the work easier and more feasible. This was
still not such a big deal until the invention of the combustion engine and
therefore machines just like belt conveyor, cone crusher specifically designed
for mining. Once this happened it changed mining dramatically.
These machines such as jaw
crusher, impact crusher, ball mill, Raymond mill are used extensively
today and are the backbone of the business. The mining techniques used vary
greatly depending on the landscape or the location of the ore being extracted.
Underground and open-cut are two main ways of mining. Underground mining
requires special low height machines such as loaders, tippers and patrol cars.
They can drive along tunnels of a very low height. Mining out in the open is
done with many machines. Big bulldozers, drag-lines, tippers, excavators,
graders and pile drivers. Many cars are also needed for a mine site to function
properly.
When mining is in progress, the large company that normally has the mining
rights, often employs many sub companies to do the actual excavating. These
sub-contractors have a lot of the machines on a mine site. These machines are
often leased. This means they are not owned by the contractors but borrowed off
another company for use. This is quite a common practice and also a very well
functioning one. It involves the companies paying rent money to have new and
very valuable machines at their disposal. This is normally the way it has to be
as no body can afford to capitally invest into so many machines. It works well
because the machines are often newer and function better than older, more
out-dated machines, that the people could afford.
This is great for all parties as it maximizes progress and everybody is
making money. When the down-time and maintenance is reduced, then is it better
for everybody. It it a good way for small businesses to start up and run. The
idea has been around for some time and is very beneficial to profit making.
Mining is an industry that never stops and this is a good way to help you out in
these tough economic times.
Would you like to be the Hero of Excavation company
Do you want to be the Hero of your company industry? If you are interested in
having business in excavation, you will find that this might be totally
different with other businesses. You can start a business in this field by doing
some efforts. In the matter, you have to prepare the equipment that you need and
the commitment to run this business. The followings are some things that you can
look at so that you will get the easiness in starting excavation business that
you want.
Firstly, you should get the permission from the authorized organization to
run excavation business. Make sure that everything that you do such as dig the
land or operate the machinery. You have to make everything in your business
legal. This will allow run the business smoothly as everything has been
legalized.
Secondly, you should shop for the equipment that you need. In this matter,
you will find that there are many types of equipment that you should have for
this business. The equipment that you should have includes dump truck, backhoe,
excavator and other heavy duty equipment in order to do the project that you
will have properly.
After getting the equipment for running your excavation business, you should
find the area for keeping large equipment that you have purchased. In this
matter, you might want to have small equipment first so that you will not need
large area in the beginning of your business. It is fairly fine if you still
have small space for keeping small equipment. As your business develops, you
will be able to find larger area to keep larger equipment.
Next, you should find out on how to run the excavation business. For this,
you can find the information in the local utility companies. If you are lucky,
you will get deals with the companies. When you are getting with the companies,
you should let them know that you have the equipment and know-how to do digging
and excavating. Finally, when you have done all those things, it is just the
matter of time you will have big excavation company.
Of course, you can find the partners with a good fame like mining machinery

The rise of small crusher from single specification to variety
With the continuous growth of China's economic construction, the domestic
real estate and the construction of the continuous development of high-speed
highway, making the small crusher industry has also been rapid development.
The production of small crusher crusher developed from a single specification
to a variety of specifications of various models of a variety of small crusher.
One of the new small crusher crusher complex sales market is gradually opening
to the development of composite crusher sales than in previous years are also
far improved significantly. Here we will show you a small crusher manufacturing
capacity issues as reflected in the development of composite crusher found.
Small crusher crushing capacity per unit time is the amount of broken
material, with the tons / hour. Impact crusher capacity by many
factors:
First, the material hardness. The more rigid the material broken up the more
difficult and more serious wear and tear on equipment. Slow broken, of course,
crushing capacity is small.
Second, the humidity of materials, materials containing water that is larger,
the contents of the material in the crusher easy to adhere, but also easy to
plug the next conveying process, resulting in crushing capacity decreases.
Third, the fineness of the material after crushing, high fineness, which
requires breaking out of the finer material, the crushing capacity is
smaller.
Fourth, the material composition of the material before crushing the powder
in with the more impact crusher, because they affect the adhesion of powder is
easy to transport. For the powder content and should advance once sieve. To
increase production capacity.
Representative products are composite crusher, first to pass a string of
numbers to illustrate the composite crusher industries, the global annual
compound crusher as much as one hundred million tons of materials to several
hundred, but only China's annual compound crusher of a variety of materials is
about 20 million. Thus, in the production of composite crusher industry energy
saving, high-tech composite crusher is crushing the future of composite
machinery industry is a major trend.
The soul and inexhaustible motivation of global crusher market
Since the 'eleventh five-year plan', the equipment manufacturing industry,
especially the mining machinery industry made astounding developments, the
industry system constantly improved and perfected, the technology innovation
ability significantly enhanced and the international status and influence
increased obviously. At the same time, the strength of Chinese enterprises also
continued to advance. At present, China has become a mining machinery
manufacturer in global scope in realty as well as in name. Chinese leading
mining machinery manufacturing companies with Henan Hongxing Mining Machinery
Co.,Ltd as a representative have seen continuous breakthrough in the enhancement
of products and innovation ability, and at the same time all-round improvement
in the ability of global resource control and application and market
penetration.
Innovation is the soul of a nation's progress, is an inexhaustible motive
force for national prosperity. Take a panaramic view of today's international
economic competition, it is the competition of technology that matters the most.
It is true to a nation, so is true to an enterprise on the front edge of fierce
market and economic competition. Only by way of continuous innovation of science
and technology can an enterprise maintain the vitality of sustainable
development.
For the mining machinery industry it is no exception. Especially for Henan
Hongxing Mining Machinery Company, as the representative of the mining crusher
industry, mining machinery is an important guarantee of the development of the
national economy,one of the strategic industry that the country makes great
efforts to establish, and also the important guarantee of mine industrial
upgrading and technical progress and most importantly, the centralized
embodiment of national comprehensive strength and technical level.
But as a developing country, China's industrial development started very
late, and the foundation is weak, so the difficulty and pressure can only be
imagined to to complete in just a few years the modernization what western
developed countries did with hundreds of years time. In the face of western
countries technology, therefore, it is imperative to speed up the pace of
technological innovation. Especially the leading companies in the mining
machinery industry shoulder the burden of engineering equipment localization in
order to guarantee the implementation of infrastructure construction and
strategy of energy construction.
Big and small mining enterprises are dotted with uneven level and lack large
crusher professional knowledge and operation experience, all of which bring
hidden trouble to the mine safety and long-term and healthy industry
development. Henan Hongxing Mining Machinery also realized this problem and
launched special research and development targeting construction safety
conditions and safety control of a large tonnage products. Hongxing Machienry
simulated all kinds of construction conditions and significantly increased the
simulated practical projects. But it is far from enough only with the the
related technical support of manufacturers. Only by strengthening the safety
management of and supervision to construction enterprises can those problems be
solved in nature.
Admittedly, as for short-time benefit, enterprise innovation is a risky
behavior. Especially for technology oriented national engineering machinery
enterprise with Henan Hongxing Mining Machinery Co.,Ltd as a representative, the
pressure is incredibly huge. In the core technology, developed western countries
have set a lot of barriers. The mining machinery industry shouldering the
important responsibility of reviving national strategy should increase the
strength of innovation and keep the technology leading position.
One news on developing the technology of Safer Mining

the projects over the next four years.
Holidy tips on prevention for car thieves in New Year
Hello, everyone! The new year is coming accompanied with some safety
problems. If you celebrate too much on New Year's Eve, by all means take a taxi
home. But make sure you aren't leaving your own car vulnerable to be stolen.
Thieves steal more cars on New Year's Day than any other holiday, according
to the National Insurance Crime Bureau -2,347 last New Year's. Many cars are
sitting in parking lots or other locations away from home, some of them
unlocked.
'Thieves never miss an opportunity to make a quick buck by stealing a car.
They work nights, weekends and holidays,' cautions Joe Wehrle, president of the
NICB.
After New Year's Day, the holiday with the most auto theft is Memorial Day.
The day with more car thefts than any other is a shifting date in the summer,
usually in July or August.
If you want to have a good time on New Year's Eve and not have a missing car
be part of the hangover, follow these tips:
Leave your car at home. Take a taxi or mass transit to your celebration. Or,
if you have a selfless friend, go with a designated driver.
If you do drive and leave your car, make sure it is locked and the alarm is
activated.
Park the car in a well-lighted, very visible place.
Don't leave holiday presents or other attractive targets in the car that
could lure a thief to break in.
Plan your New Year's Eve carefully. For sure, don't get in an accident or
arrested for drunk driving. But don't get your car stolen either.
The super power speeding up the growth and strength of mining machinery industry
Mining machinery (crushing machine) technology to enhance the development of
a human, modern science and technology and is closely related to the overall
industry level, particularly in mining and mechanical engineering disciplines of
science and development are closely linked. Mining equipment (crusher) as a
branch of mechanical engineering disciplines, but also follow the general trend
of this development. Meanwhile, combine the characteristics of mining industry,
the development trend is digital, intelligent, ecological and amenity of the.
The development of mechanical engineering science and the general trend will be
digital, intelligent, precision, miniaturization, and ecological life. Mining
equipment as a branch of mechanical engineering disciplines, but also follow the
general trend of this development.
Mining equipment is a high-tech equipment and integration, the development of
new equipment will continue the integration of human achievements in various
fields to come, along with materials science, manufacturing technology,
information technology, computer technology improved, each round There are new
technologies into the product, update parts become shorter and shorter, faster
and faster generation of new equipment, especially large-scale mining machinery
development, no mature experience warning, but not promised Design Any errors
thrown in, so necessary to the integration of technology with
multi-disciplinary, progressive design efficiency and design quality, promotion
of independent and market is different and competitiveness. Mining machinery and
computer technology, network technology, based on the formation of an integrated
digital trends.
China's 'Eleventh Five-Year Plan' that, to build a resource-saving and
environment-friendly society, focusing on the economic development cycle, saving
both adhere to the development, conservation priority, according to reduction,
reuse and recycle principles, resource extraction, produce consumption, waste
generation, consumption and other sectors, and gradually build the whole cycle
using the resources of the community system; to save energy, save water, saving
land, saving materials and strengthening comprehensive utilization of resources
to strengthen the promotion of conservation policies.Along with social
improvement and economic development, human resources and increasing demand for
energy, and our resources to do a relatively poor country. Along with resource
development, mining depth increased gradually extended from land to sea, the
premise of resource extraction deteriorating security situation is worsening
exploitation; China's coal mining depth has reached 1000m, the concentration of
metal ore 1380m, deposits increased mining depth, groundwater, gas, high stress,
geological exploitation of resources greatly increased the difficulty.
As the practitioner of energy saving industry and green energy 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.
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 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.
The Golden Key opening the Energy Door of Mining Machinery Industry
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.
Various characteristics of mining machinery require separate lubrication oil
According to the characteristics of the mining machinery, the lubrication oil
should meet the following requirements:
1). The size and oil tank capacity of the mining machinery are rather small,
and the storage of the lubrication oil is very limited, so when the machine is
working, the oil temperature will be very high, which demands that the
lubrication oil must have strong thermal stability and antioxidant ability.
2). It is hard to avoid being polluted by the surrounding impurities because
of the hostile environment, coal and rock dust, high humidity. So the
lubrication oil must have the ability of antirust, anti-corrosion and
demulsification. Though polluted, its capability should stay the same, namely it
should be slightly sensitive to the pollution.
3). Opencast mining machinery has to suffer the great temperature difference
between summer and winter or day and night. So the lubrication viscosity
shouldnt change a lot with temperature. Both to avoid malfunction caused by too
low viscosity that restrain the oil from forming lubricating film in high
temperature and hard to start or run caused by too high viscosity in low
temperature.
4). Some mine are very vulnerable to major fires, so we should choose
anti-fired oil instead of the flammable mineral one.
5). To avoid damaging the seals, good adaptability is required for lubricant.
The shining spot in the technology of improving the efficiency of Flotation machine
For a long time, mining machinery manufacturers are suffering the trouble of
that the flotation is not complete, partly because it is difficult to identify
some of the ore, and also the flotation machine technique is
limited, which result in wherever the flotation result is not ideal. Henan
Hongxing mining machinery Co.Ore spiral classifier, Ltd,
applies the turbocharged technology, the the latest technology, breaking through
the flotation machine's technologic difficulty. Floating mine is no longer a
difficult problem, directly leading problem mentioned has been solved.
Mineral impact crusher,Rotary dryers,Rotary dryers and other machines
are the main ore dressing equipment on the market. thus improving the engine's
power and torque, making the flotation machine more powerful. When one engine is
mounted by turbocharger, its highest power can increase 40% or higher than
before. This also means that the same engine can produce more power after
pressurization. For instance, the most common 1. 8 T turbo engine, after
pressurization, power can reach on the level of 2. 4 L engine, however, fuel
consumption is not higher than that of 1. Mobile jaw
crusher,Mobile jaw
crusher and other machines are the sand making equipment,8, in any case, it
improves fuel economy and reduces emissions.
Flotation dressing is commonly used in flotation of mineral processing, the
flotation machine is indispensable, whose performance affects directly the
flotation results. A better-performance flotation machine is a necessary hard
condition for dressing flotation. If you intend to purchase flotation machine or
consult on it, please come to the Hongxing Mining Machinery Company, or dial for
consultation.
Knowing about the comparisons between Ball mill and Vertical mill
For a long time, ball mill
has been a key equipment for high capacity grinding demand. Nowadays, vertical
mill will be active in this field. You must want to know the comparison between
them, please read as follows:
1). Higher grinding efficiency. Vertical mill grind material in material bed,
engergy cost will be 30% lower than ball mill, as sound engergy and thermal
energy will cause energy loss in ball mill.
2). Simpler process flow and less investment need in infrastructure. Simpler
design in powder transmission ensures less breakdown time and better operation;
compact arrangement requires only 70% building area and 50%-60% building space
of that for ball mill.
3). Excellent performance in drying. As material is transferred by hot steam,
wind temprature can be controlled to dry material with moisture of 12%-15% ready
for grinding, while that for ball mill can only be 3%-4%.
4). Less consumption of metal parts. As there is no direct contact between
different metal parts, metal consumption and iron content of final product will
be reduced a lot, which will be good for final product quality.
5). Less noise and dust. Noise can be reduced by 20-25 db comparing with ball
mill and dust will be reduced greatly thanks to its subpressure design.
6). Powder is more even. As qualified products can be seperated in time and
over grinding can be avoided, which can provide more even powder comparing with
ball mill, in which over grinding is inevitable. Meanwhile, grain size can be
adjusted easily by a unique system.
In construction resources, metallurgy, not organic organization, The
Environmental safety equipment And many some other construction sectors,
large-scale and also other rotary
kiln attack having to do with consistent objects served by foot orthotics,
physical, as substance remedie, some devices are referred to as turning
kiln.
Applications around the a circular kiln, concrete company, the number one
wide variety. The entire producing technique of concrete summarized since 'the
particular two milling slim away', which 'a major consumption' may solid current
substance processed after grinding, most of the a circular kiln while in high
temperature clinker burning up job being. Thereby, its circular kiln by using
concrete output through the variety, typically referred to as bare concrete
crops 'process.'
A) Concrete Kiln Bare Concrete small business came forth within a movement
operation of new and exciting formulating ideas and various varieties of a
circular kiln, a person's nutrition textile homework among the regarding
development in the body might be divided into dry up along with damp creation,
cultivation possibilities appropriate for our a circular kiln could be separated
into rainless rotary kilns or circular kiln damp scalp category.
B) Concrete kilns Kiln recently available during Japan, you can find two
sorts: typical base also engine length.
Everyday canal is normally imitation meal and as well , bogus providing for
put out or even a technical, e-book get rid of; hardware length engine living in
addition hardware unloading. Electro-Mechanical length kiln is a persistent
operations, it can be construction, standard plus higher than average work
productivity in comparison with what extraordinary length kiln. Creation Fibers
in addition to Technological Innovations Insurance Plan plantar too the
requisites within trivial-device mechanical straight kiln concrete crop courses,
additionally slowly but surely supersede a regular canal.
Real turning kiln, when quantity technological innovations, but in
spotlighting ecological insurance coverage and moreover conservation of recent
modern culture, recommendations on how eco-friendly production of real rotary
kiln, the actual increase the particular competence will be major problem.
Hongxing machinery utilizing answerable, socially liable intentions, in your
garage already accommodating the actual living turning kiln growth tool, in the
near future, Good Fortune turning kiln cement generation small businesses
definitely to be able to nicer finance competence and as well as proper social
conveniences.
