The advantages of impact crusher are high crushing efficiency, low power consumption, uniform product particle size, which can reduce the number of crushing stages, simplify the production process, and is suitable for large-scale and medium-scale crushing production. The company's PF series impact crusherPF series impact crusher is a device that uses impact energy to crush brittle materials with compressive strength of no more than 350Mpa, which has the advantages of large crushing ratio, uniform product particle size and less over-crushing, low energy consumption, large range of product particle size adjustment, and selective crushing, etc., and carries out medium crushing and fine crushing operations for medium hardness materials.Multi-cavity uniform crushing, suitable for crushing hard rock homogeneous plate structure makes the discharge more small particle size and cubic shape, no internal cracks and low large feed, the layout of the production line and the increase of the feed size, full hydraulic opening, repair and replacement of wearing parts Impact crusher is a kind of crushing machinery that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at high speed, when the material enters the plate hammer action area, it is broken by hitting the plate hammer on the rotor, and then it is thrown to the counterattack device to be broken again, and then it is bounced back to the plate hammer action area from the counterattack liner to be broken again, this process is repeated, and the material enters the one, second and third counterattack chambers from large to small and is repeatedly crushed until the material is broken to the required particle size and discharged from the discharge port.
