Continuous improved technology and diversified market demand promote the continuous development of the mining machinery industry in China. It has become the inevitable trend for manufacturing industry to transform from the production-oriented manufacturing to a service-oriented manufacturing; mining machinery industry will undergo a transformation, resulting in better and more comprehensive development. It will be a long time for Chinese engineering machinery industry(ball mill) going flourishing because the debt of the merger is that the risk will explode itself during the industrial shuffle high. 2Ed on July, Qingke Research Center announced a set of merger statistics of the Chinese enterprises. During the first half year in China market, among the 422 merger cases, machinery manufacturing in the lead you have completed 50 cases which account for 11.8%. Since 2001, the engineering machinery industry has a hard time. Along with a continuous fall in investment growth of the real estate and infrastructural construction, the large shrinkage of the downstream demand in various engineering machinery products, and financial strain of the guest room, these enterprises adopt a low down payment or even zero down payment of the sales model to stimulate marketing in order to gain their customers during fierce competition. This overdraft sales strategy has already exposed the risks.

Up to now, pumps, valves and hydraulic components (ball mill) needed in small engineering machinery basically rely on import. The foreign corollary parts enterprises should first satisfy the demands from its domestic enterprises. Second, they should also meet the demand of the foreign-funded enterprises in China. At last, the demands from Chinese enterprises should be considered. The restrained affect from this situation on our engineering machinery enterprises is going to become more and more evident. Among the engineering machinery enterprises this year, it has taken as long as a year and a half for some of them to pay off the money to the foreign enterprises corollary.

Continuous improved technology and diversified market demand promote the continuous development of the mining machinery industry in China. It has become the inevitable trend for manufacturing industry to transform from the production-oriented manufacturing to a service-oriented manufacturing; mining machinery industry will undergo a transformation, resulting in better and more comprehensive development. As a branch of modern manufacturing, mining machinery in China has relatively fast development pace, great market space and good development potential, but the problems of overall hysteretic development, internal irrational structure and poor technical level are still important development bottleneck hinder the development of the whole industry. Thus, under the guidance of the national macro-control, strengthening technical innovation, attaching much importance to education, improving product quality and creating excellent brand become important measures to promote the development of the mining machinery industry. With the continuous development of China s economy, the efficient processing equipment market is expanded. National policies continue to actively introduce advanced processing equipment and production technology, which continually innovates and develops mineral processing equipment in China and has made a very good result.

Mining machinery industry is the basis of building an independent industrial system for a nation, and it is also the pillar industry of our national economy. With the development of economical construction, technological progress and social development, mining machinery for example, jaw crusher making, provides advanced and efficient equipments for railway, steel, hydropower project and so on, at the same time, it also gains crucial achievements in mining and processing of raw material for further discovery, metal, chemical industry and building materials. According to the figures, mining machinery industry of our country increased 2551.77 billion RMB of the output value, increasing 33.61% compared with last year. The sales value is 2473.68 billion RMB, increasing 33.90% compared with last year. In the first four months of the year 2012, the total output value of mining machinery industry reached 969.19 billion RMB, increasing 20.22% compared with last year, and the industrial sales value reached 928.81 billion RMB, increasing 20.64% compared with last year. Due to the development of domestic basic industry and infrastructure, the demand in mining machinery industry is booming, and the increase of industrial output and sales value stays steadily between 32% to 40%. However, the national economy enters a stage of adjustment and rational regression, so some of the economical incentive policy gradually withdraw. All of this leads to the intensive contradiction between demand in the market of mining machinery and the expected goal of the enterprises, thus bringing fierce competition in mining machinery industry.

What s more, in recent years, the output of companies increased too fast, and the upgraded sales methods Reed the market demand. Improper operation often occurs and all of these actions disturbed the order of market. Then how to make the mining machinery industry keep to normal increasing speed and move back to the steady developing status? First, companies should avoid the old road of homogeneous competition, making mining machinery industry develop healthily and orderly. Then, companies need to introduce advanced technology, quicken the scale expansion and talent cultivation, and narrow the gap between domestic market and the developed countries. More importantly, enterprises should treat reform and readjustment as the focus, building famous brand, making mode transition and connecting the industry chains, so that companies can promote core value of the competitive system. In the near feature, once the demand in mining machinery industry of our country drops or appears market saturation, it will bring sufferings to the development of mining machinery industry. Therefore, to gain a healthy development of mining machinery industry, such as ball mill manufacturing, both the government and companies should make their efforts.

The roll crusher(jaw crusher) is compression type crusher, and it is made up of roller, bearing, adjusting device and driving device etc. How does roll crusher adjust the output coexistence? There are adjusting devices (wedge or gasket) between two rolls, with adjusting bolts fixed on the top of wedge. When adjusting bolts hang up wedge, the wedge will drive moving away from fixed roll roll. Roll crusher insane compression, with two rolls rotating about using a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the PIN angle.

The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Usually, these crushers will have teeth or raised on the face of the roll forms. Roll crushers used for mineral and metal Owers Han smooth faced rolls. The machinery manufacturing methods of Hongxing roll crusher and rod-teethed crusher has always been a mystery in machinery manufacturing industry. Hongxing roll crusher has been awarded three national patents. Now, let our experts share their technology with us patent.

First of all, driving system works like this: two motors drive rollers through triangle belt transmission. The two rolls force the ore particles between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Secondly, the coexistence out of the equipment can be adjusted. The particles are drawn into the gap between the rolls by their rotating motion, to wedge block formed between the rolls and the particle, called adjusting device. Finally, the transmission part should be installed safety cover by current requirements for safety. Toothed roll crusher have teeth on the face of the roll, and it is designed with high capacity. The connecting method about motor and speed reducer adopts hydraulic coupler. The equipment is mounted with overloading protective device to ensure operation. The gap width between the rolls can be changed by hydraulic adjustment system. Centralized lubrication system can lubricate all parts. Tooth design optimized. Dust is a problem continually affects the production efficiency of roll crusher in daily use or maintenance process, now we are analyzing this question. In order to reduce dust caused by air leakage, we often water the entrance when the material is dry in the current production which con the filter bag burnt and feeder blockage. When the dust enters into the dust collector pipe, the bend at the inlet increases system resistance and the bend parts are susceptible to be worn and blocked by dust. After being rained or watered, broken material will be of high moisture, the dust particles are thicker than that of dry materials, the bag filter are easy to be burnt and the feeder is easy to plug, which result in bag filter resistance substantially increased ventilation, ventilation and dust aggravated decreased capacity. Too much stoppage in bag house and component parts not only affect the normal deducting crusher, but also increase the workload of the equipment maintenance.
