1.Description of Jaw Crusher 

 Jaw Crusher for Polybasite is firstly researched and developed in 1858. Due to its simple structure, stable and reliable work and convenient operation and maintenance, it had been widely applied in mining, quarrying, stone crushing and road and bridge construction since then.
Jaw Crusher for Polybasite is one of the most important crushing machines in the stone crushing production line. It can be not only used for crushing stone materials, pebble and coal and be called stone Jaw Crusher for Polybasite, but used for manufacturing cement aggregate.
The XBM Jaw Crusher for Polybasite is widely used in mining, building materials, chemical industry, metallurgy and so on. The Jaw Crusher for Polybasite is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa.

2.Features of PE Jaw Crusher for Polybasite

1. Effectively solves the problem of high operation rate and little maintenance time caused by low output of limestone crusher. 
2. Can complete the crushing work of large-sized limestone. 
3. The blending of the two materials is even and the mixing quantity of the desulfurized limestone is greatly increased. 
4. The electricity needed is reduced. 
5. The granularity of the wastes is small. 
6. Effectively improves the labor strength and the working environment of the workers.

3.Work Principle of Jaw crusher

The strip and strip pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the movable jaw runs down, then the materials are crushed into pieces. It will become bigger when the movable jaw runs up. The movable jaw board leaves the fixed jaw board under the action of pole and spring , then the end products come out from the crushing cavity.
