岩石破碎机如圆锥式或颚式破碎机 ,在其破碎元件 ,如颚板的锰钢或其它钢种耐磨衬板上装设淬硬的楔形嵌入件。该嵌入件从破碎元件的破碎面延伸到其对面 ,在使用时 ,其作用主要是靠冲击破碎岩石 ,而不是靠压力粉碎岩石。此嵌入件由焊接或压配合被固定在热处理过的锰钢耐磨衬板上 Rock crushers, such as cone or jaw crushers, have hardened wedge inserts on their crushing components, such as manganese or other steel wear plates for jaws. The insert extends from the crushing surface of the crushing element to its opposite side. In use, the insert acts primarily by impact crushing the rock instead of crushing the rock by pressure. This insert is welded or press-fitted onto a heat-treated manganese steel wear liner
