Jaw Crusher is a primary crushing machine used for coarse crushing plant in stone quarrying and mine ore mining process. It has properties of large crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, and low cost. So this kind of jaw crusher can be widely used in mining, metallurgy, iron ore, building material, highway, railway, water project, chemical industry, etc, for crushing various material with compression strength less than 320MPa.

Jaw crushers are equipped with one fixed and one moveable crushing jaw (moving jaw), both of which support crushing plates (wearing parts) in several versions. They form a wedge-shaped crushing zone. The walls of the crushing zone are made of replaceable wearing sheets. Crushing is done between the two crushing jaws. The moving jaw of the single toggle jaw crusher moves elliptically. A pendulum motion is being carried out by the double toggle jaw crusher.blake jaw crusher is is widely used in mining and quarry.

The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring pulling rods keep the whole system in a condition of nonpositive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads. A flywheel is provided in the form of a pulley. Due to the favorable angle of dip between the crushing jaws, the feeding material can be reduced directly after entering the machine. The final grain size distribution is influenced by both,jaw crusher is the adjustable crusher setting and the suitability of the tooth form selected for the crushing plates.

The following is the process of jaw crushing plant:

The Big materials are fed to the primary jaw crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact crusher or cone crusher by...
