Bimetal Side Plates For Impact Crusher

An innovative solution for side plates in impact crushers.

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.

Comparison With Other Steel

ComparisonAdvantagesLiner Cost
Bimetal vs Alloy steel liner
  • 200%-300% wear life increased
  • No weak points at the hole area, and assembly bolts are no longer required, easier to install (Pre-bolted)
100%-200% increased
Bimetal vs Manganese steel liner
  • 300%-400% wear life increased
  • No weak points at the hole area, and assembly bolts are no longer required, easier to install (Pre-bolted)
