Detailed Description of Primary Crusher:

Primary Crusher widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other departments. Jaw crusher can crush different kinds of materials which the compressive strength is not more than 320MPa, is the first choice of primary crushing equipment.

The Main Features of Primary Crusher:
1)High capacity
2)High reliability 
3)Adjustable for easy wear parts 
4)Over-loading protection 
5)Simple structure and easy to operate
6)Easy replacement of wear and spare parts 
7)Energy-saving equipment: Stand-alone energy-saving 15% ~ 30%, the system energy-saving more than doubled 
8)low noise and less dust

Working Principle and Structure of Primary Crusher:
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves. So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
