For achieving desulfuration Hongxing publish the new limestone milling system
The emissions of SO2 have caused great pollution to atmospheric environment.
In recent years, the desulfurization of power plants and steel mill is
particularly important and urgent. Limestone flue gas desulfurization is a
common gas desulfurization technology, which is to use limestone to remove the
SO2s gas. The desulfurization efficiency may reach above 90%, this method has
been the most used and mature way in theworld.
The type of powder technology is crucial to the success of the
desulfurization project. We recommend Vertical Mills, MTW Series European Tech.
Grinding mill, and TGM Series Trapezium mill among many kinds of powder making
processing. The MTW Series mills in Kefid Machinery are most international
advanced grinding equipments, and TGM Series mill are the star products compared
with domestic similar equipments.
Henang Hongxing has researched and developed many kinds of specification
mills since 1987. Our products are exported many countries, and they are the
first choice replacing of traditional ball mills.
Mining machinery industry sustains China economic construction
Mining Machinery is for the energy, transportation and raw material-based
services industry, the main task is for the deep processing of coal, steel,
nonferrous metals, chemicals, building materials departments of mining and
processing of raw materials, as well as railways, highways, utilities and other
large projects construction to provide advanced, efficient technology and
equipment. Accordance with national priorities to support energy, transportation
and raw materials and other basic industrial development, industrial policy,
mining machinery such basic industries as the backbone of the country should get
priority for key support, should be further developed and improved for the coal,
metal and nonmetal mines development provide more advanced international
standards of quality, efficiency, environmental protection, energy saving
equipment to meet the economic development needs for energy and raw
materials.
Mining machinery, plays a very important role in economic construction,
advance of science and technology, and social development. The development of
mining machinery is closely related with the technological advance of human, the
modern science and technology, and the whole industry level, especially with the
development of mechanical engineering and mining engineering. The mining
machinery manufacturing industry,especially crusher, is not only the foundation
for the state to establish an independent industrial system, but also an
important mark to measure the industrial strength of a country, which belongs to
the pillar industry of national economy.
Mining equipment manufacturing sector should accelerate the technology reform
pace of mechanical equipment under the guidance of national policy, optimize
product structure according to market demand, and increase savings in order to
have a more long-term development. Forming a manufacturing and development
capabilities, ability to project into, and innovative capacity of business
entities, the machinery and equipment business into a market competitiveness and
risk-resisting ability of modern mining equipment business groups, efforts to
provide energy saving mining equipment, to reduce mining the user's risk and
investment as a starting point, and make positive contribution to the
development of China's mining equipment industry.
China overbudened house price relates with ball mill market
In recent years, the house price of China is abnormally high for hundreds of
millions of ordinary people, and which is overburdened for them to purchase,
they only have to sigh deeply with the price and have nothing else to do. With
the rapid development of economy and the process of urbanization and
industrialization, the investment to infrastructure , such as road, railway, and
water conservancy will be increased, which will leads to the rigid demand to
mining machinery. Meanwhile, more housing construction will directly stimulate
the development and expansion of ball mill market.
It is generally acknowledged by the industry insiders that at the peak moment
of real estate, wholesale building concrete is needed, and considering the full
use of energy source and environmental protection, it is really very
troublesome. While the application of aerated concrete relieves this condition,
for the raw material of this comes from coal ash, sand dust, coal gangue, and
waste residue. Ball mill is not only the indispensable production facility in
cement, mine, metallurgy and ceramics, but also the fine grinding machinery in
industrial production.
It is ore grinding equipment that use steel ball to work as ore grinding
medium, is the key equipment for recrushing after the material was crushed. Ball
mill has many types, such as cement ball mill, energy-saving ball mill, ceramic
ball mill, intermittence ball mill and so on. They are used for the grinding of
lime, gypsum, sand and slag. The grinding process is high power consumption, and
ball mill is the essential department in aerated concrete equipment. The
building industry promotes the development of aerated concrete industry, as well
as stimulates the widely use of ball mill.
Nowadays, China sticks to the sustainable development of 'reduce, reuse, and
recycle'. We can see that, the government-led, business-oriented, and
community-wide participated energy conservation pattern is gradually formed in
China. Energy conservation is not only the urgent pursuit of the development of
industry, but also related to people's livelihood. With the technology
development of ball mill, its environmental protection and economical efficiency
is getting more and more attention. Therefore, only the continuous energy
conservation and innovation can realize the permanent development of ball
mill.
For crushers even all machines wear-resistance is significant
Wear-resistant parts, known as immortal industry are widely applied in
building materials,cement industry,metallurgy, mining machinery, thermal power,
and such like. In recent years,China strengthened the integration efforts to
cement industry, and unveiled the policy of Green Manufacturing. In order to
adapt to the development requirements of cement industry, wear-resistant
material industry should be guided by the scientific outlook on development and
insists on taking the road of sustainable development.
Advanced casting technique is the prerequisite to the development of
industry;therefore,every enterprise should adopt advanced casting equipment,
such as producing liner plate by ways of EPC, V, and VRH, adopting advanced
technology for heating processing the continuous thermal treatment furnace of
fire coal, fuel oil, and electricity, adopting water, oil, atomizing, quenching
medium to go on thermal treatment, or adopting advanced cleaning equipment to
make sure the perfect appearance quality. Thorough physical and chemical testing
means such as spectrum analyzer, plasma cutter, impact tester, universal testing
machine, abrasion tester, ultrasonic testing, and X-ray testing are the
assurance of the crusher parts industry.
At present,there are many small and medium-sized enterprises whose input for
scientific research is relatively less, and whose product innovation is low. To
promote the development of the industry, the most important thing is to combine
Crusher parts material with high technology, improve the level of technology
research and development, and integrate internal industry structure, to develop
towards large-scale industry.
The treadstones laid in the road of Crusher industry
In recent years, China has achieved rapid economic development and has played
a crucial role in machinery manufacturing industry, especially in the mining
machinery industry. But China's crusher still has a large gap with the world's
advanced crusher industry and, there is still a long way to go. How can we make
a breakthrough in this competition? Accelerating scientific and technological
innovation is our unquestioned choice.
1) Infrastructure provides opportunities for the development of mining
machinery
The applications of mining machinery are closely related with infrastructure,
besides, after the financial crisis, china adopted a series of policies and
measures that stimulate domestic demand and promote the stable and rapid
economic development, which include 4 trillion investment into 'growth'
measures, thus stimulating a new round of investment enthusiasm of local
governments, 'livelihood projects' become the number one investment choice. In
local government investment plans, the focus is still the railways, highways,
power machines, real estate and other infrastructure projects, which are closely
related to the mining machinery industry in China. This provides China mining
machinery industry with the new opportunities of development, meanwhile, put a
higher demand, the mining machinery industry needs to speed up technological
innovation, improve the technology content, to earn more market area.
2) Poor technology holds up industry development
Compared with international advanced level, China's mining machinery in
general was 15 to 20years lag behind; the majority of crusher technology was
introduced from abroad since the mid-1980s. The market share of domestic mining
machinery products is less than 80%. Among the imported products, most of which
are large, fine, sharp sets products, such as coal mining machine, large scale
efficient separation equipment, crusher and grinding equipments.
Since reform and opening, the main route to improve the technology level of
products is to exchange market for technology. The development process of the
machine design of each country in the world is an evolution process, which
experienced single product design, single product workmanship design and whole
set workmanship design. Therefore, at present, the design of mining crushers and
other machinery manufacturing sectors and enterprises are relatively weak, so
mining machinery manufacturing industry should not only improve their expertise
condition, but also unite different forms that domestic and foreign professional
designing institute.
The extensive stage of relying on cheap labor and develop economy at the cost
of environment has been out of date, mining machinery industry need to explore a
suitable and sustainable path as soon as possible in this low-carbon era, all of
which ask for the transform of concept of all levels of government, as well as
the mining machinery manufacturers, so that they can widen their vision and
develop their industry in an international perspective.
Our dryers are rich in Modernist and Post-modernist design style
In this paper the use of dialectical materialism and historical materialism,
the view and method, from the perspective of philosophy of science, modern and
post-modernist view of science made a more comprehensive comparison.Drum dryer Full-text is
divided into four chapters:
Modernism and post-modernist design starting with the construction start. For
a long time, architectural design is a very small number of elite service,Sand making machine
which is the history of Western architecture can be clearly seen, as its
architectural design is not for kings and services, is for the church service,
or to serve the country. U.S. critic Robert Hughes (Robert,Jaw breakers Hughes)
called 'the poor do not design'. From the age of 20 before and after the
beginning of modern Europe, a group of designers, construction companies to form
a force,Limestone rotary
kiln setting off the modern sense of the so-called new building campaign.
Although the content of this movement is very heterogeneous, with the ideology
of modernism is consistent. Including the spiritual,Concentrator table
price ideological reform - designed to democratic tendencies and the
socialist orientation; including technological advances, especially the new
material - reinforced concrete, flat glass, steel use,Concentrator table but
also new forms - against the Any decoration simple geometric shapes, and
functional tendencies, thus bringing the class society in order to design
services for the elite position and the principles of breaking down and put
several thousand years completely dependent on the construction of wood, stone,
brick tradition has broken down.
Raymond mill
Modernist design from the architectural design began soon affect urban planning
and design, environmental design, furniture design, industrial product design,
graphic design and almost all the areas of communication design has become an
unprecedented, massive design movement.
Modernist design movement in the 20th century, the fifties and sixties, due
to technical developments and changes in people's aesthetic ideas, people
modernist art form a single design, simple neglect of the pursuit of rational
and psychological needs of consumers, leading to product form of monotonous and
tired of more and more criticism, so the emergence of so-called 'post-modernist'
design art.
Look back into Year 2011, Hongxing Machinery make great contribute for charity
Recent years, many disasters and affairs happend in China and also the world.
For example, at 2:28 p.m. on May 12, 2008, occurred in Sichuan 8 magnitude
earthquake, most areas of the country there is clearly felt, the epicenter of
Wenchuan County in Aba, the earthquake caused serious loss of life and property,
the current People's Liberation Army has marched disaster relief, rescue the
wounded as soon as possible. General Secretary Hu Jintao, Premier Wen Jiabao has
also been the first line of direct relief in the affected areas.
People in disaster area suffered heavy casualties, an instant lost their
homes, lost loved ones, national befell the catastrophe, the pain of the pepole
still pity.
Disaster, we can not just fall into endless grief, at this critical moment,
Henan Hongxing Mining Machinery Co., rapid response, has suffered a serious
earthquake hit compatriots to donate the first batch of emergency disaster
relief fund 50 thousand yuan. Meanwhile, the company issued to employees 'take
concrete actions to support the disaster areas' initiative, all staff donations,
contributions from 15,433 yuan and 100 Hong Kong dollars, equivalent to 15,521.3
yuan.
'A difficult one, P Plus support.' As the biggest mining machinery production
and export base, over the years, Henan Hongxing Mining Machinery Co., Ltd., as
the quality of life, from the user to God, and always follow the right for each
process, each a product is responsible for every user is responsible for the
quality policy and dedication to customer service, our company's development
must also bear the return of social responsibility, focus on love and facilities
of the uniform, and always put 'people first' as its starting point and the end
result.
Various kinds of brick crushers in removing building and construction waste
Brick Cusher also called brick breaker, which is a machine to process waste
brick. Brick Crusher has mobile brick crusher and fixed brick crusher. The brick
crusher is also has many different types according to different working
principle: brick jaw
crusher, brick mobile crusher, brick
cone crusher, brick
impact crushers The
brick crushers motor transmits power through belt, drives the moving jaw to do
periodic motion towards the fixed jaw by the eccentric shaft. The angle between
toggle plate and moving jaw plate increases when moving jaw moves . So the
moving jaw moves towards the fixed jaw. The Brick will be crushed in this
process. The angle between toggle plate and moving jaw decreases when moving jaw
moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the
final crushed brick will be discharged from the outlet.
A brick is a block of ceramic material used in masonry construction, usually
laid using various kinds of mortar. It has been regarded as one of the longest
lasting and strongest building materials used throughout history.
Many City has more and more construction waste. We have no space for these
construction waste. For Making use of the construction wast again, the
government relevant departments have to sort waste, removed or crushed, most of
them can re-use of renewable resources such as: steel scrap, waste wire, scrap
wire, and various scrap metal accessories. The brick, stone, concrete and other
materials is the main of the construction waste. By crushing, the waste brick
may be able to sand for mortar, plaster, play concrete pads, etc. The crushed
brick can also be used to produce block, brick paved road, brick and other
building materials lattice. Based on this phenomenon, we suggest the use of mobile crushing
station.
First, the commonwealth of mobile crushing and screening equipment, bulk
materials on a variety of large-scale multi-stage crushing. Another mobile
crushing equipment, small footprint, equipment flexibility, convenience,
mobility, and can save a lot of infrastructure and relocation costs; to conduct
on-site crushing of material transported from the scene without having to
re-broken material, and with the surface mining of raw materials advance of the
move, which significantly reduce the cost of shipping materials. Mobile crushing
plant configuration flexibility, the design can be modified according to the
actual on-site or special mobile crushing plant, ideal for construction waste
crushing.
In hydraulic engineering construction, manufactured sand has bright road
Many large western hydropower projects in Tenth Five-Year Plan will come
into operation with the rapid development of the west regions in China,. In the
proposed hydropower projects, the natural sand is quite lack. So it is
inevitable to adopt the manufactured sand. For that, to research further the
processing technology of artificial aggregate will be useful for improving the
quality and benefits of engineering construction.
In the large-scale water conservancy, aggregate production always pays more
attention. The new sand-making craft and the advanced equipment can improve
greatly the reliability of manufactured sand, ensuring the product quality and
saving the project investment.
For the large-scale water conservancy, especially the project with large
quantity of concrete and high-strength, concrete aggregate processing has large
scale. The production of manufactured sand can be separated with the coarse
aggregate.
The manufactured sand can produce separately, and finish the automatic
control, reduce the allocation of administrative staff. The product quality can
achieve the real time monitoring by the computer and adjust spontaneously.
When the production scale of manufactured sand is less than 200t/h, and the
aggregate quality in artificial stock ground is easy to control, it is suggested
to think the drying way for production. In this case, it can not only save the
total investment for the project, but also satisfy the environmental protection
easily.
In a word, the manufactured sand processing in the future will aim at the
quality control and cost saving. With the unceasing appearance of new equipment
and the continuous perfection and maturity technology, it will play an improving
role in the hydraulic engineering construction.
'Immortal industry' is known as wear-resistant materials which are widely
pplied in building materials, cement industry, metallurgy, mining machinery,
thermal power, and such like. In recent years, China strengthened the
integration efforts to cement industry, and unveiled the policy of Green
Manufacturing. In order to adapt to the development requirements of cement
industry, wear-resistant material industry should be guided by the scientific
outlook on development and insists on taking the road of sustainable
development.
According to the phenomenon that the price of wear-resistant materials is
increasingly rising, the wear-resistant materials industry should ceaselessly
research and develop new materials on the basis of market demands. Any material
has its advantages and disadvantages, so the enterprises should improve the
level of scientific research to develop new wear-resistant materials with high
performance. Besides, they should also develop different moulding sand and core
sand such as high density clay sand, resin sand, etc. according to various
working conditions and alloy specialties.
Advanced casting technique is the prerequisite to the development of
industry; therefore, every enterprise should adopt advanced casting equipment,
such as producing liner plate by ways of EPC, V, and VRH, adopting advanced
technology for heating processing the continuous thermal treatment furnace of
fire coal, fuel oil, and electricity, adopting water, oil, atomizing, quenching
medium to go on thermal treatment, or adopting advanced cleaning equipment to
make sure the perfect appearance quality. Thorough physical and chemical testing
means such as spectrum analyzer, plasma cutter, impact tester, universal testing
machine, abrasion tester, ultrasonic testing, and X-ray testing are the
assurance of the wear- resistant material industry.
At present, there are many small and medium-sized enterprises whose input for
scientific research is relatively less, and whose product innovation is low. To
promote the development of the industry, the most important thing is to combine
wear-resistant material with high technology, improve the level of technology
research and development, and integrate internal industry structure, to develop
towards large-scale industry. As the majordomo of wear-resistant materials. For
this tendency, we Hongxing people are always trying our best to produce high
quality brand products to evelop towards diversification and branding, building
the first-brand wear-resistant material as well as world famous brand.
If impact blow bars decides the life of impact crusher or not
You cannot emphasize the blow bars is the life of impact crusher too
much. Impact crusher mainly depends on the tremendous impact brought by blow
bars for the crushing of materials. Blow bars is the main wear-resistant parts
of impact crusher, and at present, most of the blow bars in market is made of
high chromium material, which is of poor wear-resistance and blow hardness. A
workman must first sharpen his tools if he is to do his work well. How can you
guarantee the capacity and performance of the impact crusher without good
wear-resistant parts?
In order to change this kind of situation, the experts from the R & D
team of Henan Hongxing reasonably adopt the most advanced nanotechnology at home
to make the cost performance of wear-resistant material improved 1-2 times after
the repeated research and experiment of the crushing characteristics of impact
crusher. The high chromium blow bars made by super alloying and advanced
smelting technology, whose service life is 50%-150% longer than traditional blow
bars. Compared with the products of the same kind, this blow bars features high
security, strong wear-resistance, low cost, etc. The blow bars from HXJQ have
the following distinctive features:
1). Applying the external refining technology, effectively reduced the
harmful elements, impurity and oxygen and hydrogen harm, and greatly enhanced
the abrasion resistance and impact toughness of the steel.
2). Using proprietary metamorphic agent for modification treatment, fine
grains, improve carbide configuration and distribution, and to improves the
abrasion resistance and tenacity.
3). Optimizing heat treatment process, make the product of uniform hardness
especially, impact abrasion resistance becoming stronger.
The important role of Jaw crusher in mine exploitation plant
China's infrastructure construction has developed rapidly, such as the
airport, high iron, highway, bridge, tunnel, large water conservancy and
hydropower facilities, and real estate industry, and the demands for high
quality raw materials are also increasing. It has become the consensus to
construct modern stone processing plant and produce high quality of sand stone.
For large quarry and mineral processing enterprise, we recommend you to use jaw crusher of Henan Hongxing
Machinery.
Jaw crusher is the most common crusher, it has a feature of large broken,
uniform particle size, simple structure, convenient maintenance and etc. It can
be divided into coarse grinder and fine grinder. The main technical parameters
of Jaw crusher is the processing power and feed size which is allowed with
maximum, The specifications of jaw crusher is based on the length and width of
the feeding port, our company has produce recently the latest PEF1200*1500 model
of jaw crusher,which has big norms production and strong ability. It is the most
suitable equipmentlarge for daily production of sand field. Henan Hongxing's jaw
crusher is the deep cavity equipment, its broken journeys is longer, so it is
beneficial to grind the material. Compared with the same kind product, it has
the larger production. for design and manufacture of large jaw crusher, Henan
Hongxing Mining Machinery Co., LTD. has a leading level at home. As one of the
fist product, jaw crusher is mainly used in the first broken production line. It
not only can be used alone, but also can be used with other ancillary products,
such as mobile jaw crusher.
Jaw crusher is a crushing equipment which has so extensive utility, but
crusher has many types, function and application of jaw crusher also have many
different. Customer should depend on their needs to choose, don't blind to buy,
make oneself unnecessary loss.
Crushers in Hongxing keep up with the level of the world
Some market competition stronger consciousness in the enterprise, the
constant development of new technology, a target on the domestic high-end users
and products based on the components and independent production, in export trade
friction constant international situation, domestic equipment and parts will
naturally and foreign competitors and suppliers according to force fight. So
crusher in the future development gravity of the center in the revitalization of
mechanical constantly shifting to the base technology and basic parts, in order
to improve the independent research and development up manufacturing level.
The overall size of the mechanical manufacturing industry in our country has
broken into international production country ranks, as our country mining
machinery industry of constant exploration and innovation,the whole competition
and development has been basically in the future which close to manufacture
level of developed countries .
China manufacturing industry market is very wide, including chemical
industry, mining, construction, water conservancy, metallurgy, coal mine, glass,
and other industries. In China's most important application fields are cement
industry, mining, application and pave in this send several industry of the
whole industry accounts for about the crusher of around 30%.
In the increasingly fierce competition in the international situation, the
enterprise group's hard fighting, the research and development tactics continue
to expand the international market, enterprise jaw crusher, counterattack
crusher, impact crusher, cone crusher, large grinding
machine has been sold at home and abroad.
New control technology applied in ball mill - I tell you
Intelligent frequency conversion control technology is mainly used in the
high efficient and energy saving ball mill of cement industry, the
mill itself also has high milling efficiency, save energy and lower consumption.
The details of the intelligent variable frequency control technology are as
follows:
1. AC frequency conversion and microcomputer control technology.
It can automatic tracking the variation of the motor speed control inverter
by the detecting the changing current of the motor rotor loop which is processed
by the computer when the current flow through the control center. The control
converter change the alternating current with a frequency of 50HZ into a
sameelectric potential with the current frequency of asynchronous motor
rotor.
2. Intelligent technology, which can automatically enter and dephasing,
technology structure is with a the characteristics of no contact, no wear, no
rotating part and capable of automatic diagnosis and repair fault.
3. According to the different grinding process and the grinding
characteristics of different positions, there sets a Archimedes spiral enhance
lining plate and a double curved surface lifting grading lining plate with
different lifting force on the high efficiency and energy saving ball mill . It
sets a efficient combined compartment in tube for inner classification, which
forms the unique properties of the balanced powder abrasive flow and it provide
a activation loop in a fine grinding barn, which strengthen the grinding
function.
The ball mill set machinery, electronics, micro-computer control in one
through the large capacity high voltage intelligent reactive power compensation
of frequency control technology applying in energy saving ball mill, which
realizes the reactive power compensation of the tube mill power drag, automatic
diagnosis and repair fault, realize the grinding efficiency, low power
consumption by the use of the programmable intelligent.
With the change of environment and the deterioration of the pollution, all
walks of life have begun to research low carbon life, now low carbon economy has
also become a development trend for crusher areas.
At present, our country has more requirements for the environmental
protection of crusher equipment and gradually improve quality of products. The
old crusher which has a feature of load noise and high resources consumption has
not adapt to the pace of development. However, with the constant technology
innovation, crusher also gradually update. The noise of crusher equipment is far
smaller than the olds, power consumption also decreases greatly, and degree of
material broken also is rising now, so it furtherly narrows probability of he
material rework to break. The development of new technology produces industry
breakthrough, it has gradually achieve the our country's 'low carbon'
requirement.
We constantly stressed the 'green', 'environmental protection', but it just
is 'low carbon' in the final analysis. Although 'low carbon' is emerging product
of economic development, it is a topic which we pay attention to for a long
time, it just is changed call; 'A low carbon economy' is not just a problem
which China faces, but also a global problem; 'Low carbon development' is a
specific technical and creative problem, but also is the primary issue for the
way of the economic development. In the face of the development pace, we can
read, low carbon development involves not only 'people's livelihood', but also
'countries plan'.
For the crusher industry, if we want to develop a low carbon economy, the
most important link is efficient one-time broken. So we can leave out the
unnecessary resource consumption which the secondary crushing causes, and also
reach the high production efficiency. And the use of the crusher can greatly
reduce natural sand mining, this protects both natural resources and environment
for human survival, and accords with sustainable development strategy.
It's a rigorous work to run the sand production line
Because it is a series of equipments instead of one sand making machine from starting
the sand production line to its normal operation, the operation is a very
rigorous work, so there must be a professional personnel to start it. Owning to
the multi-equipment, hard work, high degree of difficulty, which requires the
staff very well master the run and operation steps. We will introduce few
operation specification and matters need attention in the operation, and the
details are as follows:
Matters need attention when starting a sand making production line : after
preparation, according to the provisions of the driving sequence operation to
start the main motor, when starting the motor we shoul pay attention to the
current meter of the control cabinet, after starting the peak current for
30-40s, the current will reduce to a normal operating current value. In the
normal operation, we also should pay attention to current which should not be
more than the specified value. After the normal operation of the jaw crusher, it can actuate the
feeding machine, and according to the block size and the operating condition of
the jaw crusher adjust the feeding machine belt and change the feed quantity.
Usually, the material stacking height in the crushing cavity should not more
than the 2 / 3 of crushing chamber, and the diameter of the materials should not
be more than the 50%-60% of the inlet width, the jaw crusher has a highest
production capacity at this condition. When the materials with larger piece, it
will cause blockage affecting the normal production. To prevent metal ( such as
the spade teeth, crawler plate, bits ) from entering the jaw crusher and avoid
damaging the machine, it should be brought out when they pass through the jaw
crusher to prevent causing accident; when the electrical equipment automatic
trip, if the cause is unknown, forbid forced continuous starting.
Clearing the operation specification of various equipments in sand making
production line is very necessary for the safe to human body and equipment
application.
In efficient coal exploiting, crushers as well as grinding mills
The exploration and utilization of coal has played an important role in
economy development, but causes great damage on environment. Coal gangue and CBM
development are the main wastes. The coal gangue is the solid waste produced
during the excavation, mining and washing process of coal. It consists of
carbon, shale and sandy shale, and has a low calorific value. The carbon content
is 20% ~ 30%, some contain humic acid. They exist in large quantity in countries
of rich coal resources, which not only piles up the place and contaminate the
environment but also causes fire due to auto-ignition. As energy is increasingly
short, people gradually realize these wastes are employable. If the coal gangue
can be differentiated and crushed by breakage and grinding equipment, such as jaw crusher, impact crusher,
grinding machine, they can be utilized to achieve economic benefit in roughly
five aspects:
1). Filling the colliery. The coal gangue can be used as filling materials in
underground coal cavity directly or after processing.
2). Filling the ground such as road building.
3). Generating power. Coal gangue containing rich carbon and high calorific
value is used for fluidized bed and circulating fluidized-bed power
generation.
4). Building materials. The coal gangue is made into gangue brick, cement and
lightweight aggregate to act as building materials.
5). Extracted sulfur ore or other chemical products from coal gangue and
other
All these utilizations need crushing by jaw crusher, impact crusher, Raymond milling
machine, High pressure suspension grinding mill, micro-powder mill.
The further steps on the stage of small crusher markets
With the development of construction industry, machinery industry expands
fast, such as crusher market. The varieties of crushers are many, jaw crusher, impact crusher, small jaw crusher,
cone crusher, hammer crusher, roll crusher, mobile crushing station
... Here, we talk about the future of small crusher market.
Along with our country the acceleration of highway construction, small
crusher industry in recent years to get its rapid development, the market has
the rise. According to information, at the present time, the both product can
normally use, and small broken equipment utilization is increasing. Pavement
construction industries make small crusher products circulation quickly, the
market situation were promising.
As is known to all, China is a big country, but according to the mineral
resources in China, the characteristics of mineral resources in exploitation, we
must be careful to the dressing, so, the mineral processing machinery industry
in China to bring the very big development space. From last year at the in
Tianjin China mining and this year in Nanning china-ASEAN mining cooperation at
the BBS that countries continue to intensify for mineral exploration, and
increasing the development of mining investment policy to encourage Chinese
companies to go out of the country and the world mining resources development
cooperation.
As a conclusion, the demand of crushers will continue to increase, but at the
present China mining machinery enterprise with foreign trade enterprise overall
difference is bigger, the products less competitive. So crusher product price
and the same products abroad also have a large gap, increased research efforts,
improve product quality is still domestic crusher enterprise most need the
problems faced.

The ways to enhance the effect of coarse flotation and increase flotation capacity
As we know, there are two main types of ore beneficiation process:
flotation process (Flotation machine) and
magnetic process (Magnetic saparator). In each type, there are also coarse
beneficiation and fine beneficiation. The flotation effect for coarse grained
mineral grains is poorer in general process conditions. In order to improve the
coarse grained flotation, we can use the following special process.
1. Selection and adjustment of the flotation machine
Practice has proved that the strong turbulence movement of pulp in the
mechanical agitation flotation machine is the main factors to promote ore grain
fell from bubbles. Therefore, we should reduce turbulence intensity of pulp
movement, which can be the ultimate measure for coarse particle flotation. So we
can take measures according to the specific circumstances.
(1) We should choose the special flotation machine which is suitable for
coarse grained flotation, such as flotation machine of ring shoot type, skinnier
type flotation machine, bubble sorting and fluidized flotation machine, etc.
(2) We should improve and adjust the structure and operation of the
conventional flotation machine, we can reduced groove depth (use shallow groove
type), shorten float up journey of the mineralization bubbles to avoid mine
grain fall off, we also install flotation above the impeller area to dampen the
pulp turbulence intensity, and to maintain stable foam area, to increase air
inflation capacity, in order to form more air bubbles. So it can promote the
formation of magnetic particles float group and it makes coarse grained rise up.
When we scrap the bubble, it is quick and smooth.
2. We can properly increment pulp density and improve reagent regime.
We should choose the strong power of collector and rationally increase
inhibitors consistency, the purpose is to increase the solid strength between
mineral and the bubble, speed the risen speed, in addition to add nonpolar oil,
such as diesel, kerosene auxiliary of collector, it can 'consolidate'
surrounding which three-phase contacts, to enhance the solid strength between
mineral and bubbles.
