Double Roller crusher  is widely used for fine or superfine crushing in the industries of mining, construction materials, metallurgy, chemical industries and so on. It can crush all kinds of materials under middle hardness, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, chemical materials and so on.

Roll Crusher is widely applied in the industries of mining, building materials, chemical industry, metallurgy, etc.

Roll Crusher can crush materials with middle hardness or less than middle hardness into secondary or fine granularity, such as crushing mineral, rocks, coke, coal, slag, scoria, and fire-proof material etc.

Double roller  Crusher working principle:

When  thedouble roller  crusher works, the raw material is fed in and fall into the V type crushing cavity between the two crushing rollers and crushed into qualified sizes by the extruding and cutting force of the two counter-rotating rollers, and then discharged from the outlet.
The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotates inward simultaneously. The materials are extruded, crushed and ground, then the end products come out from the bottom of this roll  crusher.

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.
