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. The space at the bottom of the "V" aligned jaw plates is the crusher product.

Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1”) product which places more load on the crushers downstream in the circuit. Many producers refer to jaws as “breakers” meaning that they break the rock down to a size manageable.

Jul 24, 2003 . There is little process control employed at aggregate crushing plants and essentially no optimization at the primary or jaw crushing stage. Jaw crusher selection is very dependent on the subjective judgment/experience of individuals, the characterization of rock material using inadequate and.
