The jaw crusher is used for coarse, medium and fine crushing of various ores and rocks with a compressive strength of 147-245MPa. The maximum compressive strength of the crushed material is 320Mpa. Performance characteristics of rock crusher: this stone crusher has large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance and low operating cost. The working principle of the quarry crusher: when working, the motor drives the eccentric shaft to rotate through the pulley, so that the movable jaw periodically approaches and leaves the fixed jaw, so as to squeeze, rub, and grind the material multiple times, so that the material changes from large to small, gradually drop until it is discharged from the discharge port of this stone crushing equipment.
