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, up to 350 MPa compressive strength of stone crusher with crushing ratio, after crushing the material was cubic particles, etc; PF-II series Impact crusher is suitable for crushing hard materials, such as cement limestone crushing, with production capacity, the expected size of the advantages of small crusher can be divided into categories according to medical crusher and mining crusher. Medical crusher which is mainly used for crushing stones, the general resonance stone crushing way to avoid the risks caused by surgery. According to the principle of crushing, heavy mining machinery used crushing machinery are jaw crusher, impact crusher, vertical shaft impact crusher, hydraulic cone crusher, hammer crusher, hammer crusher, roll crusher, Compound crusher, cone crusher, two-stage crusher, gyratory crusher, mobile crusher. Different types of crusher working principle is completely different structure of stone crusher, hammer crusher with an example: hammer crusher is mainly done by the broken material impact energy jobs. When the hammer crusher work, the motor drives the rotor for high-speed rotation, uniform material into the crusher chamber, the impact of high-speed rotary hammer, cut the material tear caused material to be broken, while the stone crusher introduction, materials of its own gravity the role of the body so that the material toward the rack from the high-speed rotating bezel hammer, sieve stone crusher performance bar in the lower part of the rotor with sieve, sieve size is smaller than the pulverized material discharged through the sieve size fractions greater than sieve size of the material retained on the sieve continue to be a hammer blow and grinding.
