Jaw crusher has a crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process the side length of 100 to 500 mm below the material, its compressive strength up to 350 MPa, with a crushing ratio roll crusher introduced after the material was broken cubic particles, etc; PF- II series impact crusher is suitable for crushing hard materials, such as cement limestone crushing, with production capacity of high quality roll crusher, the advantages of the small size of the crushed material purpose and significance of a purpose: in metallurgy, mining, chemical , cement and other industrial sectors, every year a large number of raw materials and waste recycling are needed crusher processing. As in the concentrator roll crusher features, to make useful minerals in the ore reached monomer separation, you need to use the crusher to crush the ore grinding process granularity required. Need to use the raw material crushing crushing machine next to the size of the job requirements. In the coking plant, sinter plant, ceramics factory, glass industry, metallurgy and other departments, the raw material to be crushed by crushing machinery to work the next size requirements. 2, meaning: In the chemical industry, power sector, broken machinery grinding the raw material crushing, grinding, increasing the surface area of ??the material, and create favorable conditions for the chemical reaction of materials to shorten the time. With the rapid development and rapid decrease of industrial resources, recycling waste production departments is important, then the processing of these waste processing required mechanical crushing crushed.
