The high efficiency and low consumption impact crusher of Shanghai Lipu Heavy Industry Co.,Ltd is a new product absorbing world advanced technology; with perfect impact curve, flat hammer design, new type of abrasion-proof materials and regular gravel shape, so the consumption of spare parts is decreased nearly 32%, the capacity is increased more than 20%. Our products have passed the ISO international quality system authentication and the European Union CE certification. Impact Crusher adopts the newest manufacturing technology and unique structure design, so the discharged product is with cubic and perfect shape, no tension or crack. This crusher can crush materials with size smaller than 500mm and resisting strength less than 350MPa, such as granite, limestone, concrete aggregate, etc. Impact Crusher Working principle: When the machine works, the rotor rotates with high speed when the PF impact crusher is driven by motor. Materials enter crushing chamber and impact with hammers on the rotor, and are thrown to impact plate for being crushed, and then are rebounded back to hammers for being crushed again. The materials enter the first, second and third chamber for being crushed repeatedly until they are crushed into suitable size. The final product is discharged from the outlet. Product size and shape can be adjusted by adjusting space between impact plate and rotor.
