Something about wearing parts of impact crusher: impact plate and board hammerImpact crusher crushes materials by rotary board hammer and impact plate. In this process, the board hammer and impact plate are easy to be damaged because materials are pounding them continuously, and the efficiency will be reduced accordingly.
Materials are hit by board hammer, so impact crusher has to bear impact force produced by this, and then this process is repeating for materials crushing. There are polygonal-shaped impact crusher and arc-shaped impact crusher according to force analysis. Polygonal-shaped impact crusher can crush materials vertically and the effect is pretty good. Arc-shaped impact crusher can make materials rebounded to a circular crushing area for processing, which realizes free crushing. The impact plate is usually made of wearable steel plate, and its impact surface is equipped with scaleboard, which makes abrasion performance better.
