Jaw plates (fixed and swing jaw plate) are the most important wear parts of jaw crusher. We use high manganese steel with chrome as the material to make sure the quality.

Raw materials are crushed to small aggregates between movable jaw plate and fixed jaw plate. So movable jaw plate impacts raw material directly during the operation-time. Supposing that it is damaged, raw materials will impact the movable jaw of jaw crusher and the machine service-life will also be affected.
