A jaw crusher primarily consists of two plates: the fixed jaw plate and the movable jaw plate. The key to its operation is the reciprocating movement of the movable jaw plate, reminiscent of our very own jaw’s motion when we chew. This physical process exerts sufficient force on the input material, often large chunks of rock or ore, causing
