Mining Machinery Reserch

After decades of efforts, Chinese mining machinery industry has developed by leaps and bounds, but compared to the development level of the industry, there is still a large gap abroad, the gap is especially large in the crusher, crusher, stone crusher and other large mining equipment and Rockware equipment, such as crushed stone production line of large mining machinery products, manufacturing quality, appearance, reliability, service life, design standards. In recent years, through the introduction of products and technologies, the joint venture with foreign famous manufactures, our country s mining mechanical speed up the improvement and repalcement of techanical content production industry. Our company and the many other domestic manufacturers of mining machinery make great progress, some traditional crusher, roller, vibrational circular sieve machine are carried out the structure, performance improvements, product manufacturing process also will be further improved. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, medium crushing and crushing. the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer breaker, breaker, breaker, compound crusher roll impact. Jaw breaker (breakerr jaw), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact breaker can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact breaker machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. Typical domestic mining machinery industry manufacturers: our company, and so on. With the improvement of technology and the successful operation of the company, our company products have become a large manufacture and export of chinese large crushing mechanical production bass. The mining machinery and equipment are long-term in the situation of heavy load, and suffered the load changes with the irregular movement of time, so various safety potential hazards exist, if the danger is found late, immersurable personal and property losses will be caused. Although many kinds of modern checking equipments emerges, duo to the hinder of mining mechanical enviroment and its own technology level, some unpreidctable things happen from time to time. Although many difficulties exist now, they will be sloved one day.
