The double rollers crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on.

Working principle of roller crusher machine:

Big size stones are transferred to primary crusher through vibrating feeder from hopper for first crushing, then the crushed materials are transferred to impact crusher through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and aggregate with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed and manifold cycles. The sizes of final products will be graded and separated according to customers' requirements, and the duster will be attached for the sake of environment protection.

Features of roller crusher machine:

1. Their initial cost is lower
2.They are durable and strong
3.Design is simpler and easier to repair
4. Taking electric and torque converter double overload protection to improve its reliability and safety.
5. Fixed spacing between 2 tooth rollers makes it stable to discharge.
6. Using PLC to control the whole procedure, increase its automation level.
7. All tooth roller bearings are lubricated concentrated with lubricating grease pump, more convenient and faster.
8. Reasonable design for the shape of tooth plate and high-qualified wear resistant material extents its working life.
