Henan dominates the field of China crusher markets
In recent years, with the rapid development of the economic in China, the
energy demand mushroom, the rapid development of large scale infrastructure,
highway, railway, and real estate projects led the processing and production of
sand, gravel and other building materials, which makes the need of mining
equipment especially crushers soar. Henan is one of the biggest mining machinery
manufacturing in China as well as one of the biggest is China's largest
production base of the crusher, which is the mainstay in the crushing equipment
production and has gathered numerous crusher manufacturers in mechanical
field.
The crushing machinery industry in Henan was arisen early in 1980s and
reached a prosperity period at the beginning of 1990s. At that time, the access
threshold of producing the mining machinery is not high, so crushers
manufacturers mushroomed as bamboo shoots after a spring rain. The prosperity of
crushing machinery industry didn't promote the benign development of this
industry, but led to more and more problems. Market gradually saturated and the
disordered competition of the crushing machinery industry brought a heavy blow
to the development of the whole industry.
Entering new century, the crushing machinery industry in Henan entered the
high-speed development period once again with the rapid economic developing, the
industry once again entered the high-speed development period. However, the
flourishing of the market also led the emerging of many nonprofessional
manufacturing enterprise, the production workshop of these enterprises are with
neither professional production equipment nor professional design team and
professional technical staff, so the product quality is not guaranteed.
At present although there are many business enterprises in crushing machinery
industry, among which manufacturers with real professional production
qualification can be counted on one's fingers. These large manufacturing
enterprises are all survival from the most intense mining machinery industry
competition in the last century, and now they all have the scale of production
capacity, diversification of products and keep the technology developing
synchronization with the international. And the most important is that they has
accumulated a large number of stable customer resources and achieved the trust
of customers in the past ten or twenty years' developing.
Let us to find the pathogeny and solutions for magnetic separator
The magnetic separator
motor overheating and sound not normal . Caused by the above reasons,
including:bearing bad lubrication or severe worn , fan leaves fall off or wear ;
Switch line contact undesirable , or disconnected to run single-phase ; voltage
is too low.
In the series of magnetic ferrite magnets and general use of the sr ndfeb
magnets. One ndfeb magnets chemical stability is poorer, in magnetic drum in the
humid air,Cement rotating
dryer easy appear surface oxidation gradually layered spalling phenomena.
good chemical stability, strontium ferrite magnets generally with the epoxy
resin bond into magnetic fixed set in magnetic of, there are also magnetic piece
of easy falls off phenomenon. So whether strontium ferrite magnets are necessary
or magnets for fixed.
Magnetic separator noise is not normal in normal operation , the cylinder was
jammed by obstacles and even the cylinder can not rotate , the bottom bin
vibrate . Caused by these reasons include : magnetic separation was jammed by
the bottom bin of object , or magnet fell off , causing the cylinder rattled
,serious causing cylinder of epidermal was lacerated . At this time we should
shut it down for maintenance and troubleshooting . Reducer overheating.Its main
causes : lack of oil ,or oiliness is bad; gear and worm wear serious,or meshing
is bad; bearing lubrication is bad ,or badly worn .
Magnetic separator of magnetic field intensity becomes weak. The major
reason,including : the temperature is too high ; sun exposure ; acid and alkali
corrosion. You can use gaussian measurement meter.
Magnetic separator is composed of foundation bed ,the magnetic system under,
the rotating cage, the magnetic system above, hollow shaft,concentrate hopper
other rotating equipment . Mounting base should to make hollow bearing seat as a
criterion to measure the elevation and level of degrees. The positioning of the
magnetic system under should make mounting base as the criterion . Turn cage
,next step is the upper and lower magnetic system must be accurate adjustment of
the gap ,which limits of deviation of 0 +1 mm.
The new development direction for the worn-out parts of ball mill
Cast iron in casting process is very common in the process of cast iron
products. For its quality problem is be worthy of attention, so we must learn
about the effects of several factors of cast iron pieces of ball mill.
The first is the process operation.Control and check the quality of the
casting in the manufacturing production.
The second is to possess a reasonable casting process.
The third is the quality of raw materials in the casting. If the quality of
the raw materials dose not match the standard, it will make the iron casting
generate defects, which effects of appearing quality and internal quality or
even make the cast iron scrap.
In recent years, wear-resistant casting industry has developed continuously
with the development of our national economy. And it now has become an
independent industry.
At present, due to the inevitable and objective wear problem in the
development of the industry exists in reality. Therefore, as long as the basic
raw material industry develops, the needs of casting wear-resistant parts will
be also continuous in supply. What's more, as the ceaseless progress of industry
and the requirements of energy saving and environmental protecting, the quantity
and variety of the wear-resistant parts in demand will continue to expand. The
wear-resistant castings industry will be more prosperous and have a stronger
vitality. Therefore, we call the wear-resistant casting industry an' immortal
industry'. Welding power source should be able to guarantee the long time
continuous and stable work. The operation machine can realize automatic welding
gun moving vertical and horizontal direction. The positioner can flip horizontal
rotation and vertical. Dust removal system is capable purify the welding fume
releasing by automatic welding gun.
Rolling bearing machine also like a coin with two different sides
Rolling bearing and sliding bearing are the most commonly used bearing
equipment. Rolling bearing equipment is a very wide range of industrial
application of a bearing product , which consists of the outer ring , inner ring
, rolling elements and cage components ,owning good starting performance and
load carrying capacity , applying to machine tools , automobiles, railways and
other industrial machinery ,civilian instruments. Rolling bearing equipment is
an important modern machinery and equipment supporting basic parts.
Comparing with sliding bearings , rolling bearing radial size is relatively
large , the noise , vibration and other aspects of performance level is
ordinary, but the load carrying capacity and starting performance is excellent,
which is easy maintenance and operation results reliable . The following is the
advantages of rolling bearing .
The rolling bearing equipment's fault phenomenon maily includes : bearing
installed parts temperature is too high,in the running bearings have noise, and
rolling bearings wear.
a. Rolling bearing equipment temperature is too high
In the organization operation, installation of bearing parts are allowed to
have a certain temperature, when the hand touched institutions shell, should not
feel hot to normal, otherwise it indicates that bearing temperature was too high
. Bearing temperature is too high for two reasons :oil quality does not meet the
requirements or deterioration , lubricant viscosity is too high ; body assembly
is too tight ( lack of space ); bearing assembly is too tight ; bearing ring is
rotate on the shaft or shell rotation ; load too large ; rolling bearing
equipment can keep the frame or rolling element crush.
b. Rolling bearing equipment noise
Rolling bearing equipment allows a slight noise in the work operation, if
noise is too large ,unusual noise or crash,which indicates that the bearing is
faulty .
Rolling bearing equipment noise is more complex reasons , one is the bearing
inner and outer rings which coordinate with surface wear . Because of this wear
and tear, damaging to the relationship which is bearings and housings , bearings
and shaft ; leading to the axis deviate from the correct location,and generate
abnormal sound in the high-speed movement . When bearings fatigue , causing
peeling off the metal surface ,which can lead to increase the bearing radial
clearance so that the generation of abnormal sound . In addition, the lack of
bearing lubrication ,the formation of dry friction,crushing and other reasons ,
which will have a bearing abnormal sound . Rolling bearings wear loose ,which
lead to frame wear loose,producing abnormal sound .
c. Rolling bearing equipment wear
Rolling bearing equipment wear is common problems in the proces of using
equipment ,which is mainly caused by the characteristics of the metal shaft :
Although metal has high hardness,the yield is poor (can not recover after
deformation ), poor impact resistance , fatigue resistance is poor, which can
easily lead to adhesive wear , abrasive wear , fatigue wear, fretting wear,etc .
Most of the rolling bearing equipment wear is not easy to detect ,and only
appear : the machine is too high temperature , beating amplitude is too big,
abnormal sound ,etc.,which will cause notice . When they are found above
problems, most of the rolling bearing equipment are worn , resulting in machine
downtime .
Advantages of rolling bearing
a. Rolling bearing structure and working principle of the movement can ensure
that its coefficient of friction is low, having better mechanical efficiency .
In the process of mechanical equipment operation , it can maintain low power
consumption , and have a good starting performance .
b. Rolling bearing equipment owns a good accuracy and rotate speed ,at the
same time it can meet the operation requirements of a variety of mechanical
equipment . In the device operation rolling bearing suffers the low friction
,low wear, so it has a longer service life . In the part of some products about
rolling bearing , which can achieve self-aligning feature and more widely to
industrial needs.
c. Rolling bearing structure is compact , small size , light weight, easy
installation and removal . Rolling bearing various components are achieve the
standardized size , which is not only conducive to the production of rolling
bearings but also conducive to the exchange each other , which make it easier to
repair and maintenance.
d. Rolling bearing is most use the steel as the main material, adding
standardized , serialized component design ,which is more conducive to
large-scale industrial manufacturing, quality assurance and stability .
Pendulum feeder is a kind of feeding machine that is able to deliver blocky
and granular materials from storage silo to receiving device evenly, regularly
and continuously in the production process.Pendulum feeder has the
characteristics of simple structure, reliable operation, easy adjustment and
installation, small size and the closed type of shell to prevent dust
pollution.
Pendulum feeder is suitable for chemical industry, mining, metallurgy,
construction, mineral processing, coal and other industries. It is not suitable
for delivering the dry power or materials of big size, otherwise, it may appear
the fly-ash pollution or the discharging blocking.
Adjust eccentric gear pin on the eccentricity of the eccentric ,which can
change the length of the itinerary of the swing bottom,adjusting the volume of
feeding with a wide range, adjust the height of the discharge port gate ,change
the size of discharge hole, which be able to Feeding precise adjustment.
The pendulum feeder is not suitable for delivering the dry powder or big
grain material, it may result in the dust pollution and the jam of the
discharging holes. The chute feeder can be installed on the ground or onto
discharge port of ore bin. The chute bottom plates do the reciprocating
movement, the movement frequency is 20-60 times/min and the stroke is 20-200mm.
Stroke can be adjusted by the eccentric wheel; the eccentric throw is half of
the stroke. According to experience of some mine sites, the eccentric throw
should no less than 30mm for cohesive ore. The chute width is 2-2.5 times of
maximum feeding granularity. The biggest chute feeder can supply ore with
granularity less than 500mm. the most common specification is 980*1240 chute
feeder, with feeding granularity between 350-0mm, which is the best partner of
400*600 jaw crusher.
All kinds of rules for operating and protecting a cement mill
Cement mill maintenance is
an extremely important regular work , it should be match closely with the
machine operation and maintenance , there should be full-time personnel on duty
checks.
Cement mill maintenance
1. Bearing . Crusher bearings shoulder all the load bearing of machine ,
great relationship between good lubrication and the bearing life, which directly
affects the life of the machine and the operation rate , and thus required to
fill the oil must be clean , seal must be good , the cement mill the main oiling
Office: rotating bearings , roller bearings , all the gear , activities bearing
, sliding plane.
2 . The newly installed wheel band is easy to loosening ,we must always be
checked.
3 . Note that various parts of the cement mill is working properly .
4 . Pay attention to check the wear easily parts of degree of wear , and at
any time pay attention to replacement of worn parts .
5 , Chassis plane of putting the activity device ,removing dust and other
objects in order to avoid the machine when the material can not crushed ,and the
bottom shelf can not move up and down in the activities of the bearing, so as to
cause serious accidents.
6 . The bearing temperature rises ,we should be immediately stopped and
checked cause of trouble to eliminate them.
7 . If sound machine produces impact sound,the turning gear operation should
be immediately stopped ,checked , and eliminated .
Installation and commissioning
1. The equipment should be installed in the level of concrete
foundation,using stone bolt to fix.
2 . Installation should pay attention to the main body and level of the
vertical.
3 . After installing, checking for various parts of loose bolts and the host
doors is whether tighten, if have, tighten.
4 . According to the power of the equipment configurations power and control
switch.
5 . Check finished, empty load test, test normal can carry on production.
Our crushing machines resolve the industrial waste and waste recycle
At present, the reuse problem has attracted significant attention from all
walks of life. For example, many local governments are actively appealing for
crushing the construction trash and turn it into renewable building material and
reuse it; national policy also formulates some relevant policies and measures to
protect the environment from construction waste pollution and some ministries
and commissions have listed its reuse into the twelfth-five years plan. Reuse
and resourcation disposal will be an irresistible trend and an inevitable move
that conforms to the times development. However, it is a system project which
will get involved many management departments, so that in the current
circumstances, everyone pays attention to it, but joints forces have not formed
yet.
Demand is always the guiding of equipment manufacturing companies. So with
the emerging of trash disposal, mobile come crusher also arises at the historic
moment and constantly improves in the developing process. But because this
industry lacks standardization, the machinery quality is uneven, there even is
the condition that the mobile impact crusher
just reached the production site, the tyre gets loose.
In recent years, there has come into being a new favorite in the crushing
machinery industry, the mobile breaking station, which is able to do the special
mobile crushing according to the actual spot design and eliminate the
limitations of crushing site, surrounding and complicated basic configuration,
so that it not only can break more conveniently and highly efficiently, but
realizes the effect of reducing the occupation of land and recycling
construction waste. However, with the more and more obvious situation of the
building waste surrounds the city, its disposal and recycle is not just turning
waste into value and solving the land occupation problem.
As for the government, he should give more support to its disposal, no matter
on the capital or the policies; he should give some degree of guarantee, because
he start the beginning and walk to some distance is very important to its
development; as for the machinery manufacturing companies, equipment safety
always comes the first, and secondly how to as much as possible satisfy the
demand of high efficiency and low energy consumption is also very important.
There are many companies manufacturing disposal equipment, and the types are
jaw crusher and mobile cone crusher. What has to
mention is that the machines has be close to the international advanced level
and has gained excellent application effect. So whether the company can grasp so
superior market opportunity still need the customers to choose the best devices
and timing.
One machine in Cement Production Industry - Cment Packer
The cement packing machine is mainly used for packing cement in bags, or
other fluit powdery material's bagging work. Except manual sidekick, baggs can't
fall off unless the bulking load reach centain amount. The machine can stop
immediately when bag happens to fall of suddenly. It can charge load without
compressing air, which reduces the packer damadge caused by damaged pneumatic
components. Most of the cement packer is divided into fixed and rotary.
The work of running processes
1). Start the operation steps: The circular telegram - starts the belt
fastener - start the packer - start the feeding engine - to insert the bag - to
fill installs - measurement - fall the bag .
2). Engine off step: Closes the feeding engine - emptying the cement in the
packer - switch off the total power source .
Entire operation and routine maintenance
1). Before driving, we should pay attention to the scene environment,
eliminating the influence work the obstacle,forbidding other personnel to close
to the rotary packer besides inserts the bag .
2). Before driving, we should inspect the electric appliance part earnestly,
the velometer knob position in 0, the turn clockwise knob accelerates to need
the rotational speed gradually, each minute engine off must by all means make
the velometer return to knob 0.
3). Inserts the bag ,the body and the machine must maintain the suitable
distances, preventing to bump into and injure.
4). When fills installs, we does not permit the hand to press, the foot kicks
the cement bag, in order to avoid influence measuring accuracy.
5). When the operation appears failure ,emergency stopping maintenance ,
cutting off power supply, , listing alerts or the specialist care.
6). Packer of grounding protection wants safely reliable,and regularly test
ground resistance .
7). When the belt suddenly stop , they should immediately cut off the cement
packer rotary power to scratch-resistant package .
Advanced mining machinery pays attention to advanced crushing and grinding machine
Recently, in order to speed up the reconstruction, all sectors now has a
higher requirements to the performance of large mechanical equipments used in
the construction. Thus, the development of the mining equipment has gradually
shifted to develop and research high tech crusher and grinding mill.
As one of the mining machinery manufacturer walking in the forefront of
science and technology, Henan Hongxing has its own special insights on the
research and development of new products. We think that the quality of the high
tech crusher hammer is the key to the development of a crusher.
Take the crusher used in cement industry as an example, the working
environment of crusher in cement industry is relatively bad, which need hammer
with strong wear resistance. As with the traditional crusher equipment, because
the poor quality of the hammer, it needs to be replaced regularly. The key of
research and develop high tech crusher is to improve the wear resistance of the
hammer and to reduce the cost of the maintenance. When customers choosing a
crusher equipment they mainly pay attention to the service life of hammer,
stability in use and whether it is easy to break and so on.
Advanced crusher hammer is generally made by hadifield steel of good
toughness, high resistance, which can cushion the impact strength and increase
the wear resistance. In addition, the design of the hammer structure is also the
emphasis. The geometry design of a hammer are closely to the elimination of the
impact force, the effect is obvious especially for the hammer of large thickness
and size.
Additionally, Henan Hongxing also believe the gap problem is important, the
gap mainly refers to the gap between the rotor body and a back plate and the
hammer. The size of the gap is related to the blocking material problem, once
there exists blocking materials, it would exacerbate the wear of the hammer. So
it is necessary to design a good gap size.
Taking Hubei as an example China is getting more notice on enerty efficiency
Hubei, the birthplace of modern industry in China, is one of the important
old industrial bases and one of the three largest steel bases in our country. It
is also the largest production base of medium, heavy, sheet plates and special
steel, the second largest production base of automobiles and the largest
production base of medium trucks, the largest production base of heavy machine
tools and packaging machinery, the biggest hydraulic power base, and the largest
production base of Join-alkali, agricultural chemicals, phosphorus, salt
chemical industry and striate gypsum. It is also a national photoelectron
information industrial base in China and one of modernized traditional Chinese
medicine bases and important textile bases. It has established a distinctive
industrial system, forming a pattern with automobile, steel and photoelectron
information as advantaged industry.
Recently, problems about climate, energy and environment are more and more
serious. In order to recall the issues, the Department of Housing and
Urban-Rural Development of the Hubei Province has recently circulated a report
on the special inspection of 'building energy efficiency work and targets
completion' in 17 cities (prefectures, municipalities, forest zones) as well as
12 counties (cities, districts) in 2011.
The evaluation of 'building energy conservation' includes the assessment of
construction of management systems; formulation of supporting policies;
execution of laws and regulations; supervision of law enforcement; publicity and
training, and completion of tasks in key fields. The inspection also examines
the fulfillment of objectives, including the implementation of new building
energy efficiency standards; application of renewable energy buildings;
development of green architecture; 'prohibition of solid clay bricks'; and
application of new wall materials.
Based on the inspection results, the province has adopted effective
initiatives to implement the national and provincial laws, regulations and
standards on building energy efficiency. Building energy conservation is
expected to exceed the annual target with a production of 1.05 million tons of
equivalent coal in 2012.
Mining Equipment named China is about to spread across America
As the weakening U.S. economy, China is set over the United States next year
as the world's largest manufacturer, which four years earlier than expected.
This great leap forward by the United States provides economic consulting firm
Global Insight forecast shows. According to forecasts, China will account for
11.783 trillion U.S. dollars next year, manufacturing value added of 17%, while
the U.S. will account for 16. U.S. still topped the list last year, accounting
for one fifth of the global total. China accounted for 13.2%, occupies the
second.
In Made in China Industry all the way and sing, by leaps and bounds, we have
noticed that we are inadequate. We are just a big manufacturing country, not a
manufacturing power, and many related key we have not mastered the core
technology and manufacturing power, we have a lot to be desired. Therefore, to
develop the manufacturing sector, we must earnestly practice the 'scientific
development', and vigorously the introduction of talent, technology innovation,
so that we can really enter the manufacturing power.
The overall Chinese mining market is dominated by coal, of which 90 percent
is underground, in contrast with the US coal market, which is mostly surface
mining, according to the JPMorgan analyst Ann Duignan in a research note. After
recession hit in late 2008, the price of many commodities such as copper,
aluminum and iron ore fell as demand from manufacturers dropped off. Mining
companies idled production and laid off workers.
But since last year, metals prices have rebounded sharply, prompting
producers to reopen mines and start up idled projects. That has put a strain on
supplies of equipment, with some producers complaining they cannot get adequate
supplies.
As the famous mining equipment manufacturing industry, the largest
manufacturer of crushing and screening, Henan Hongxing Mining Machinery Co.,
Ltd. is located at the Hig-Tech development Zone Zhengzhou,China. We mainly
produce stone crusher, ball mill, sand making machine and the full
set of dressing equipments, such as rotary kiln, it is
widely used in metallurgy, mining, chemical industry, building materials, coal,
refractory materials, ceramics and other industries. Since the establishment of
the company, we have always manufactured products under advanced modern
management system with independent innovation and brought together a number of
talents in science and technology.
We always regard the quality of the products as the life of enterprise and
our products have pass the certification of international quality system
ISO9001, 2000. The after sale service is the last of ensuring quality. We have
an experienced and skilled after sale service team which offers tracking service
all over the country.
In the mining industry, roller crushers are used to crush mines of medium or
low hardness, rocks that have low or medium rigidity during mine selection, for
cement, chemicals, and industrial production of building materials, among
others. However, their use in the mining industry has greatly declined due to
their inability to produce large amounts of output. In mining applications, the
roll crusher does not match up to cone crushers, when
considering the volume of production and maintenance costs. However, roll
crushers have the advantage of producing a close distribution of the product
size. In cases where the ore is not very abrasive, the maintenance costs are
significantly reduced.
Roll crusher work, paying particular attention to the following:
1) to strengthen the work to the removal of iron ore. Non-broken material
(solder first class materials) fall into the room on roller crusher damage,
resulting in parking accident. Therefore, lithotripsy should be installed before
the addition of iron device.
2) viscous material easy to plug the break room, plug in the treatment
failure should stop processing, not to poke mine in operation.
3) when dealing with were more of materials with large, easy to pay attention
to large deposits of space squeezed out from the broken to prevent injury or
equipment damage.
4) roll crusher run a long time, due to the roll surface wear larger size too
small will lead to products, then adjust the arrangement to pay attention to
mine mouth or on the device for maintenance.
5) to strengthen inspection of the equipment, lubrication equipment, parts of
the fuel on time, maintaining good lubrication equipment.
Importance and views on developing the Coal Industry
Coal, which is an important fundamental energy source and raw material of our
country, and plays an important strategic role in the national economy, will be
the main energy source in the primary energy structure of our country for a long
time. From the opening and reform, the coal industry has rapidly developed, its
output is on continuous increase, its production technical level is gradually
enhanced, the work safety conditions of coal mines are also improved, and the
coal industry has played an important role in the national economy and social
development. However, there still exist many prominent problems in the
development of the coal industry, such as the illogical structure, extensive
growth pattern, low scientific and technological level, recurring safety
accidents, serious waste of resources, retarded environmental control as well as
many other problems left over by history. Along with the development of national

coal industry and other relevant industries, the overall arrangement of
collaborative development of the coal exploitation and the ecological
environment, the overall arrangement of collaborative development of the economy
of mines and the regional economy, a new type of coal industrial system suitable
for the socialist market economic mechanism shall be built, the continuous,
stable and sound development of the coal industry shall be realized, and the
construction of a conservation-minded society shall be accelerated so as to
provide reliable energy resources for building a well-off society in an
all-round way.
From 2005, three to five years shall be used to build a well-regulated coal
resource exploitation order, build large-scale coal bases, engender several
large-scale coal enterprises and enterprise groups with the production capacity
of more than a hundred million tons, largely improve the basic safety conditions
of coal mines, effectively control the gas of coal mines, effectively control
the recurring tendency of major and utterly serious accidents, evidently make
the work safety of coal mines more favorable, basically control the aggravating
tendency of the ecological environment of mining areas and gradually perfect the
system of coal regulations and policies.
Strengthening the planning administration of coal resources. The coal
resources are important strategic resources, therefore the administrative
pattern shall be improved so as to realize the transformation of scientific and
rational exploitation and protective and intensive administration from the
extensive exploitation administration. The nationally planned mining areas of
coal resources and mining areas that are important to the national economy shall

Facing the flourishing Mining Mafia how does Alwar do
The flourishing business of illegal mining in Alwar is taking place under the
patronage of district administration and police department, claims intelligence
report of Rajasthan police that TOI has. As per the report sent on October 18,
2010, T Gutie, the then inspector general (intelligence) mentioned that in lieu
of allowing illegal mining, the authorities receive monthly payment from mine
mafias. The report says that due to proximity to national capital region (NCR)
around 1,500 dumpers reach Delhi and Haryana daily without any hurdles.
A 50-member team that went to Kahrani village in Alwar district to stop
illegal mining on Sunday was attacked by the illegal miners. More than six
policemen were injured, out of which three have been admitted to a hospital.
After the Supreme Court's (SC) decision where it came down heavily on state
government's inability to restrict illegal mining, authorities have geared up
their efforts to shut these mines.
The team was able to close down 27 mines in Tijara and seized 50 stone
screening plants along with 8 crushers at Udhanwas in Alwar. 'Following the SC
orders we have been taking action against illegal mines and have shut down four
dozen units in the past few days,' said JP Jakhar mining engineer. He added,
'With the help of police department we have dismantled the stone crushing units
and seized the crushers and other equipment.'
There is full support of officials from police, forest, mines and district
administration to provide uninterrupted transportation. The copy was sent to the
then home secretary, PK Deb. Despite these intelligence reports no action was
taken.
After the strong criticism by the Supreme Court the district collector had
issued orders for firm action against illegal mining. 'We are following the
orders of SC and all the steps are being taken as per the instructions from the
honorable court,' said Ashutosh AT, district collector, Alwar.
Illegal mining is carried out in entire RAJASTHAN and every officer
responsible to check it is getting its share .Whether he is from Central Govt or
from forest ,revenue ,police and mining.All politicians upto rank of minister
are involved.
RWE Power is one of Europe's leading energy utilities and Germany's biggest
coal miner. The company would help R-Power design and plan the engineering
aspects of captive mine and procurement of equipment and ensure quality control,
the company said on Thursday. Government has allocated Kerendari B and C coal
blocks of North Karanpura coal fields in Jharkhand to meet the fuel requirements
of the Tilaiya project. These mines have reserve of over 1 billion tonne. The
company plans to produce 40 million tonnes of coal per year.
'Although a great deal of research has shown that physically-imposing
individuals are more likely to acquire power, this work is the first to show
that being powerful may actually make people feel taller than they are. We found
that people literally perceived themselves as taller when they occupied a more
powerful position,' the Telegraph quoted Prof Goncalo as saying.
This is a good arrangement for R-Power to have experienced mining Company to
plan, design and mine coal from captive mines from power generation. Arrangement
will be helpful for Indian power customers as long as the cost of power produced
by this arrangement is going to be reasonable. The cost control and efficiency
in producing coal should a key factor regarding success. Indian government and
the State need to a watchful eyes in this type of projects. Everyone should win
from use of national resources for the good of the people. Government needs
update its tax structures along with the ever increasing energy prices up wards.
Proper monitoring and tax policy should keep the project winwin for allthe
stakeholders.
Two important part for mining industry - Crushing and Grinding
In the mineral processing industry, production costs cover more than 40% of
the total cost on average, while the production costs of grinding covers more
than 40% on average. While the investments of grinding equipments account for
about 60% of the total investment of mineral processing industry.
All the processes that make large particle materials into small particles
through outside force can be called crushing, the mechanical appliance is called
crusher. All the processes that make small particle materials powder through
outside force can be called crushing or grinding. It can be called powder mill
for short. The machinery can be called pulverizer and grinding mill .The
machinery that combine the crushing and grinding can be called crushing and
grinding machine.
In the cement industry, the role of broken grinding costs in the cement works
are around 20% of production costs, and electricity consumption of crushing
machinery accounts for about 10% of total electricity consumption, while the
powder mill accounts for 60%.
With the economic rapid development of modern society, The demand and
production scale of all kinds of metal, nonmetal, chemical minerals, as well as
cement, building materials increase gradually, so the material that needs to be
crushed and grinded is increasing rapidly. Since the 90s, the annual amount of
material through the broken grinding is up to 100 million tons. China's annual
output of brittle materials has already reached more than 1.5 billion, of which
about 240 million tons are iron ore, more than 100 million tons of nonferrous
metals ore, more than 260 million tons of non-metallic minerals, over 30 million
tons of chemical minerals, about 400 million tons of cement ,more than 470
million tons of limestone for building. Most of these materials must be broken
through the grinding, so we can see crushing and powder projects play a huge
role in the national economy.
Many different types of stone
crusher, stone crushing production line are often used, complete production
line and mineral sand production line stone, stone crushing production. The
current breaker Heavy machinery industry has developed into a relatively large
branch of industry, the benefits of working the heavy machinery crusher
applications for the current situation and the stone industry in a variety of
different quality characteristics, according to different Application of sums up
the current industry crusher several major categories, including jaw crusher, impact crusher, hammer crusher and a cone crusher and so on.
The whole pulverizer is of a standing structure and characteristic of a small
occupying space and strong integration capability. It can form up an independent
production system from lump material crushing to finished powder and packaging.
The electrical system of the pulverizer is centrally controlled and the advanced
model is rationally selected. Basically, an unmanned operation can be realized
in the pulverizing workshop. The lightweight and compact vibration feeder can
feed the material uniformly. It is easily adjustable, energy saving and
convenient for operation and maintenance.
Good equipment quality can shape nice enterprise fame
According to the industry policy that our country will give significant
support to the development of basic industry like energy, transportation and raw
material, as the backbone of these basic industries, mining machinery should get
prior support so that it can further develop and improve in order to provide
more crushing and grinding machines with international advanced level for the
exploitation of coal, metal and non-metal mining hill, and satisfy the demand of
energy and raw material of national economic development. The mining equipment
mainly includes jaw crusher,
sand maker and
powder-grinding machine, among which crusher is the most important link in the
whole rock crushing process and also the important symbol of measuring the
strength of the mining facilities manufacturing industry.
Mining breaking and grinding machinery is devices that have high technology
content and integration and the development of new equipment is mixed together
with more and more achievements from other business scopes. With the development
and advancement of material science, information technology and computer
technology, every round of products are injected with new techniques, the update
cycle of spare part is becoming shorter and shorter and the upgrading of new
equipment is becoming faster and faster. Especially for the development of
large-sized mining equipment, because there is no mature experience that can be
learned and any mistake is allowed, it has to be researched with the help of
mixing with many discipline techniques, improve the design efficiency and
quality and enhance the companys independent innovation ability and market
competitiveness. The rock crushing and grinding devices has formed a trend of
digital development with the basis of computer and internet technology.
When we look back on the development history of crusher, we can conclude that
the main breakers are vertical impact crusher, hammer breaker and
so on. Since the types are too many, their names are different.
The impact crushing machine
developed by Henan Hongxing Mining Machinery is the example that perfectly
combined with professional breaking technology and engineering manufacture and
also the sufficient representation of new technique and processing method. It
not only can provide the best rock aggregate for the highway, railway, high
building, municipal works, hydroelectric dam construction, port and wharf and
concrete mixing station, but becomes the core equipment in the artificial sand
making industry and stone transformation scope, and more and more becomes the
mainstream machine in the business scope of metal rock breaking, quartz sand
production and slag disposal. So this series of products are well received by
customers from home and abroad at the same time.
Useful items to make a purchase for Aggregates Crusher
Road and Bridge Construction as the most basic is the most widely used raw
materials , construction aggregate for drawing convenience, wide range of
applications and aggregate nature of the product itself has received special
attention. The face of increasingly intense situation in the domestic high-speed
railway construction , local governments have thrown the future of local
planning, a large number of high-speed railway , highway project has attracted
many domestic investors.
According to the policy situation prevailing circumstances , give full play
to local advantages of supporting the construction of road administration into a
lot of smart people who supply raw materials and an excellent business
opportunity. How to choose a good aggregate and aggregates production equipment
manufacturers to become a top priority for many investors concerned.
Construction of the railway under the road level on aggregate with different
quality requirements also vary , as far as possible to improve the quality of
aggregates is the inevitable choice of sand stones factory , which Crusher, sand making machine such as
the choice of aggregates production equipment is essential.
Aggregates are usually distinguished between fine and coarse aggregate.
Aggregates are classed as inert materials, such as washed natural sand (fine);
and natural gravel, which can be crushed to produce the appropriate size and
grading of aggregate, and similarly crushed, quarried stone (coarse). The
aggregate must have a minimum inherent strength requirement for structural
concrete, the coarse aggregate must not be weaker than the concrete paste.
All aggregate must be 'clean', i.e. not contaminated with organic matter or
clay/silty soils and overburden during extraction and storage.
As we know, under different local conditions , can be directly used in some
areas inside the river channel gravel or pebbles directly processed, according
to sediment concentration and the size of the stone optional equipment : jaw crusher , the European version
Jaw Crusher , cone crusher ,
sand making machine and so on . Of course, the actual materials , of which
package of equipment includes feeder , conveyor ( belt ), Vibrating Screen and sand washing machine .
The choice of aggregate equipment manufacturers is for the aggregate market
share of fundamental significance , choose a good breaker equipment , products
subject to quality assurance , maintenance of missed work can be removed from a
lot of time to provide income for the profit of sand stones factory Prerequisite
for stable operation . Given the nature of the equipment crushing machine , the
proposed investment aggregates production companies use personal inspection
equipment , visit the crusher equipment and use of on-site workshop , rigorous
treatment of choice crusher manufacturers , not just unilateral concessions
Figure price factor , in order to avoid Forest for the trees , not worth the
candle.
