Jaw Crusher is widely used as primary and secondary crushing equipment to crush material with compression strength less than 320 MPa. It is widely used in mine, metallurgic industry, chemical industry, building material, highway, railway, water conservancy, etc.

Working principle:
Motor drives V-belt and belt pulley to make moving jaw do periodic motion by eccentric shaft.  Moving jaw moves upwards to the fixed jaw when angle between toggle plate and moving jaw increases, so materials are crushed in this process.  Moving jaw moves downwards from fixed jaw by pulling rod and spring when angle between toggle plate and moving jaw decreases, so the final crushed materials are discharged from the outlet.  The moving jaw moves periodically according to the eccentric shaft movement, and the materials entering the crushing chamber are crushed and discharged continually.
Features:
1.Large crushing ratio and even discharged materials;
2.Large and reliable adjusting range of discharged outlet meets various requirements;
3.Safe and reliable lubrication system, easily changed spare parts and easy maintenance;
4.Simple structure and low operation cost;
5.Low noise and little dust pollution.
