Normally, impact crusher side plates are made of chrome steel or other steel. To unwearable problem, Qiming Casting uses Bimetal side plates instead of them.
The chrome white iron casting plate is brazed (not overlay welding) with a mild steel back plate, the top layer of the chrome plate provides excellent wear life, and the back mild steel plate provides excellent impact resistance. The liner can be made with bolts pre-welded on the back to avoid excessive wear on hole areas.
