Roll Crusher

1. High production efficiency

2. Simple operation

3. Low noise

4. Little dust

Description:The double-roller crusher is one of the crushers produced by our company for coarse/fine crushing. It is widely used in fields of cement making, chemical engineering, waterpower, metallurgy, construction, fire-proof material making, etc. It is suitable to deal with medium-hardness materials like limestone, pebble, clinker, coke, etc. The material to be crushed should have fracture strength less than 300MPa and humidity less than 35%.

Features:1.High reduction ratio and productivity. 2.User-friendly. 3.Reliable operation. 4.Uniform-sized finished products. 5.Reduced noise level. 6.Environmentally friendly. 7.Sensitive over-load safety device. 8.Adjustable feed opening which is suitable to deal with materials with various fracture strengths. 9.Safety device which can protect the crusher: Normally, springs can bear the force used to crush the material. If something that can not be crushed is fed into the chamber, springs will be pressed. In the case, the discharge opening becomes larger and then the unknown material will be discharged. Afterwards, the rollers return to their normal positions under the force of the springs.

Working principle:During operation, the two rollers, driven by the motor through the V-belt, rotate in the opposite direction. The material will be crushed by the rollers after passing the feed opening and then be discharged from the base. 
        The wedge-shaped device or washer between the rollers is adjustable. At the top of the wedge-shaped device, there is a bolt for adjusting. When the wedge-shaped device is pulled up by the bolt, the rollers will leave the fixed wheel. In the case, particles obtained become larger. While the wedge-shaped device moves downwards, the distance between the rollers becomes short under the influence of pressed springs. In the case, particles obtained become smaller. By increasing/decreasing the number or thickness of the washer, larger/smaller particles can also be obtained.
