A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a “V” alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate.
Normally, it consists of 1 piece fixed jaw plate and 1 piece movable jaw plate. In order to rotate and exchange more easily, movable jaw plates also have 2 segments design and 3 segments design.
Crusher jaw plates working principle is based on the reciprocating movement of the movable jaw plate that compresses and crushes the stone or ore between itself and the fixed jaw plate, as the material enters the zone between the jaws.
