With the development of economy, crushing equipment has been widely used in more and more industries. Dr. Mark Hyman spoke with conviction. Currently, most of the concentrators still use the mechanical crushing, crushing equipment which is mostly a nearly century-old device, the main structure of the basic legacy has not changed, but be involved into a modern new technologies and new materials, so the crushing devices be greatly improved performance. In industrial production, Crushing equipment types party are diversity. According to the difference of their stage crushing process, it can be divided into the primary crusher, the crusher and crusher crushing; its working principle and structure characteristics, can be divided into the roll crusher, gyratory crusher and In addition, in recent years there has been ultra-crushing crusher can produces more granular product. Crusher design new varieties can be used as coarse, broken equipment. Mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, crushing and crushing medium. The commonly used equipments are impact crusher, crusher, single stage vertical crusher, compound machines gyratory crusher, roll crusher, double roll crusher, crusher combo, and so on. 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 crusher, 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 crusher 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 crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. With the improvement of world s energy efficient awareness of environmental protection, as well as the consensus reached with the countries of the world, in order to adapt to the constant expansion of industrial production, the development of a larger crusher is the main task. Hydraulic in recent years in the crushing equipment technology has been widely used, has developed a hydraulic jaw crusher, the crusher crushing. Thus breaking the the original crusher setting adjustment more difficult and insurance port device reliability shortcomings.
