The earliest application of crusher is just limited in the mining industry, along with a better understanding of it as well as technical advances, the crusher industrial application range is very wide now, such as the process of scrap cars or electrical appliances, equipment and conveyors matchedsorting if vehicles are equipped, it can be easily automated handling and processing of scrap various industrial products, recycling of steel and non-ferrous metals and non-metallic material available. As to the dominated crusher in the world, above nearly 7% are developed on the basis of the United States Newell products, which is more representative of Germany Lindemann, Japan Fuji and China s mountain climbers Heavy. Since the successful development of new crusher in Europe in the 1980s, the manufacture of the crusher structure design, manufacturing processes and materials continue to improve and improve. Such as the German company O & K new impact breaker machine, made a special design of the crushing chamber, rebound, metal ore material may pop up. This is also the crusher application characteristics, paid great attention to foreign the composition and structure of the material. With the rapid development of the domestic economy, crusher s status in the economic and social industry are also rising, which has also become essential in many industrial production. We all know that 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 crusher, impact breaker, roll crusher, crusher compound.
Jaw crusher (jaw crusher), 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. When dealing with a variety of metals, non-metallic mineral raw materials and construction materials in the production process, in order to improve the efficiency of the grinding operation, to achieve energy saving and emission reduction targets at home and abroad have developed various types of crushers, such as a hammer, to fight back type, the fastest growing anti-vertical shaft, especially hammer crusher uniformity, high efficiency, simple structure and light weight material, easy operation and maintenance. Duo to a variety of reasons, the foreign crusher industry develops slowly since the 1980s, due to less investment in the home industry, there have not much development, making this market appears blank, less new equipment, the supply can not meet the demand of the market, so the future is broad developemt.
