Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in mining, metallurgical industry, building material, highway, railway, and chemical industry.
The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes to the fixed jaw. The stuff will be crushed in this process. The angle of Jaw Crusher between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher.

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.
