Mining & CrushersJaw Crusher
Side plates / cheek plates (jaw crusher side liners)
White iron option: extremely hard (wear-resistant) but brittle – suitable only where impact energy is low. Mn steel: tough and work-hardening – better for high impact. Selection depends on feed material hardness and fragmentation.
