Now in the market, the popular and agreed grinding machine include the ceramic ball mill, energy-saving ball mill and rod mill. The ball mill has the advantages of smaller size, even size and can apply to the grinding of the quartz and feldspar. The ball mill has bigger output size so it can avoid the damage by “over crushing”. So as the grinding machine, control the rotary speed is benefit.

Each machine, each type has its certain rotary speed when it was be designed. As all we known high speed will have high capacity. But control it to be some certain is very important. High speed, intensified campaign, also the raw material has its own energy, so the over crushing will be occurred in the grinding.

Taking ball mill as an example, Type 1224. As we all known that its rotary speed is 27-34 r/min, if we increase the speed to the 36 r/m, the capacity will be get by 4.2%. In this condition, Capacity of the size below 5mm will increase from 11% to 15%, and the metal will be 4% to 5.2%.

More knowledge, more news and more about the products come to Zhengzhou Honxing Mining Machinery Co., Ltd. which is a professional manufacturer and exporter in the mining equipment. We has strong technology, good products, and design the processing line according to the site and requirements and realize the concept of customer-first.

When we make sand, the third generation sand making machinery and the rod mill are main equipment, but we can also see the situation of the over-broken. Today, the exports in Hongxing will explain it to you.

Firstly, when the rock was sent into the rod mill, we should discharge it timely after broken. If it was grinded too long, it will be over-broken.

Secondly, the gap between the sticks are the way to protect the rock from being over- broken, if the gap between the sticks are too narrow, the sand will be over-broken.

Lastly, the compression strength of the rock is weaker than the stick. So the sand was easier to be over-Broken.

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.

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.

Wear-resistant parts,likely crusher hammers,jaw crusher plates,crusher liner,cone concaves,manganese blow bars,crusher rotors,super crusher hammers,roller press recovery,and are main used in crushers,Crawler Mobile Crusher,jaw crushers,impact crushers,hammer crushers,ring hammer crusher,sand making machine,hydraulic cone crushers,circular vibrating screen and can used in stone crusher machine,Sand Making Production machine,cement crusher machine and so on.

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.

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.

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.

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 crusher’s 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.

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.

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.

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.

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.

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.

The ball mill as universal grinding equipment, is widely used in cement, mineral processing, building materials and chemical industries, the ball mushroom machine can be divided into two kinds of dry and wet grinding method. According to the discharging in different ways, can be divided into the grate type ball mill overflow type ball mill two.

Cement quality, from the grinding process, and the mill before crushing separator efficiency has no direct relationship. China's cement quality inspection index in general there are two: Cement sieve residual value and specific surface area. Our Hongxing is committed to improving the quality of cement mill. But internationally on cement inspection standards are constantly changing, which requires manufacturers continue to improve production technology of ball mill, executive cement new standard, cement sieve residue values of this index has little practical meaning. New standards for specific surface area to pay more attention to some, but the cement particle gradation, no specific requirements. Ball mill manufacturers generally executive cement new standard, must be substantially improve cement product quality, accelerate the elimination of backward, promote market competition, with ball mill grinding cement standard to conform with international as soon as possible, as China's accession to the WTO after the cement industry into the international market for. In this way, China ball mill plant, especially small mill plant how to improve cement quality, has become an urgent need to solve the problem.

Our company mill expert expresses, improve the mill after the cement quality in many ways: adjustment of raw material proportioning, sintering process, change, strengthen the mill equipment management and so on, these are required by the production of cement units on their own, and the ball mill manufacturers also takes a long time to research and improvement, we can do is the ball mill grinding process improvements, improved the quality and output of ball mill.

Rotary kiln can be divided accoding to two approaches. The first dividing method of rotary kiln is by structure. It can be divided into horizontal rotary kiln and vertical rotary kiln. The second method is by manufacturing type. It can be divided into wet method rotary kiln and dry method rotary kiln. Wet type rotary kiln is mainly used in cement wet type production. Cement wet type rotary kiln is used to process material slurry made of raw material and water which make up around 35%. Because slurry inside rotary kiln has mobility and all kinds of material inside rotary kiln mixed fully and evenly, the cement clinker calcined in rotary kiln has very good quality. All these are the advantages of wet type production by rotary kiln. While different from wet type rotary kiln, dry method rotary kiln has opposite benefits. Dry method rotary kiln is used to process raw material of dry powder which has water less than 1%. Therefore, Dry method rotary kiln can save the energy which is used to evaporate water in wet type rotary kiln. However, the energy consumption of dry method rotary kiln is still not low because the high temperature of waste gas. And material inside dry type rotary kiln mixes badly and components of material inside dry type rotary kiln distributes unevenly. So, the most popular kind rotary kiln is wet method rotary kiln.

When the crushers used for the basalt, granite, river stone, and other high strength of hard materials, you must note that: design the reasonable crushing technology, for the investment, you should consider the stone production line cost, and also consider the investment cost in the local place.

There are three factors that affect stone crushing: the crushed materials hardness and crushed stones type, the materials silica content, water content, the materials average size, output size and the output size proportion, finished products usage, production capacity per hour, etc. In the actual crushing line, some materials are lime stone, the jaw plate’s wastage of the jaw crusher is very low, one pair of jaw plates can use one year is very normal, because limestone is low hardness, and the silica content is very low, so it is high wear ability and low corrosive.

When the materials are basalt, granite, the crusher equipment production cost is far greater than the limestone production cost, therefore, when we design the crusher equipment, try to select the laminated principle of crusher equipment to reduce the resistant parts consumption. Typical laminated crusher equipment is the stage of jaw crushers, or jaw crusher add the sysmons cone crusher technology. If the customers have high requirements of the final stones, we can select the impact crusher for shaping crushing, then this will form a three stage of crushing technology; three stage of crushing will cause the high cost, but for the long operation of stone crushing plant, reduce the three stage of crushing is possible, for the hard crushed materials, can adopt the jaw crusher and the impact crusher to form two stage of crushing technology, but this will cause the impact crusher’s impact hammer quick consumption, the blow bar is shorter life, and more returning materials, etc.

Crusher equipment industry needs to develop continually, need to meet the customers' requirements continually. In the process of urbanization and industrialization of highway, rail, water conservancy and other major infrastructure investment is increasing, which will increase the large demand for the crusher equipment. Our crusher equipment include stone crushing plant, spring cone crusher, jaw crusher, impact crusher, high efficiency fine impact crusher, building wastage crushing equipment, etc.
