Product description: Jaw Crusher is ideally suitable for primary and secondary crushing. The largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry. Working Principle: The main structure of the jaw crusher consists of body frame, eccentric shaft, big pulley, flywheel, movable jaw, cheek plate, toggle plate, toggle seat, top thread bolt, reset spring, fixed jaw and movable jaw; the toggle plate has a great role in insurance. This jaw crusher uses motor as its power. Through the motors wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening. Features: 1.The deep crushing cavity increases the feeding capacity and output capacity; 2.High crushing ratio, homogeneous final product size; 3.Adjusting the discharge opening through gasket, more convenient¡¢the adjusting range is wide, it can meet different customers' requirement; 4.Lubricate system is safe and reliable, easy to change the spare parts; 5.Simple structure, easy maintenance; consumption cost is lower; 6.Energy-saving; for one set of crusher saving about 15%-30% and more than twice for the whole crushing system; 7.Adjustment of the discharge port range, to meet the requirements of the different users.
