1.Double Roller Crusher Usage and Application:
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.

2.Working principle of roll crusher :

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.

3.Double Roller Crusher Features:
1. Compact structure, low noise and efficient;
2. Easy to install and only need simple foundation;
3. Can adjust the pressure and size easily.
4. Self-protection, the parts can not be damaged when hard materials such as the metals goes into the crushing cavity;
5. Low cost maintenance and easy to maintain.
