 Brief introduction stone jaw crusher   

The jaw crusher is widely used crushing equipment. It has two types, single-toggle type and double-toggle type.

 

Generally, the single-toggle jaw crusher is applicable for coarse/medium crushing ores and rocks with compression strength under 250Mpa. The three models of jaw crushers above PEF0609 can also crush ores and rocks of different hardness. The PEF-X single-toggle jaw crusher used for fine crushing is applicable for ores and rocks with medium hardness and below, and the double-toggle jaw crusher can be used to crush ores and rocks with various hardness and high corrosion.

 

The jaw crusher has advantages of simple structure, reliable working, easy operation, convenient maintenance and low cost for equipment and production. It is widely used in metallurgy, mining, building materials, chemical industry and cement for coarse and medium crushing operations. The jaw crusher is mainly composed of frame body, movable jaw part, toggle plates, locking devices with pull-rod spring and driving devices. The movable jaw is driven by motors for complex pendulum through triangle belt. Once the ores are poured into the crushing cavity crush, they will be extruded, split and bended due to the action of the swing jaw. The crushed ores will be discharged out at the moment when the swing jaw leaves the fixed jaw plate.

Working Principle of jaw crusher: Jaw crusher consists of frame, eccentric shaft, belt wheel, flywheel, movable jaw, side guard plate, toggle plate, toggle backseat, gap adjusting screw, returning spring, fixed jaw plate and movable jaw plate. Toggle plate is also used to guarantee the security. Jaw crusher uses electric motor as the motive power. Eccentric shaft is driven by triangle belt and genea wheel, which makes movable jaw make reciprocating motion according to the desired trajectory. Then, materials in crushing chamber (consists of fixed jaw plate, movable jaw plate and edge plate) are crushed and the finished materials are discharged from discharging hole.
