Roller Crusher Overview
Roller crusher, depending on the number of rollers, can be divided into double-roller crusher and four-roller crusher. With the advantages of reliable operation, simple maintenance and low operating cost, roller crusher has widely application in the industries of mining, building materials, cement, chemical industry, metallurgy, etc. The roller crusher can crush materials with middle hardness or less than middle hardness into secondary crushing, tertiary crushing or fine granularity, such as crushing mineral, rocks, coke, coal, slag, scoria, and fire-proof material etc.
Due to the efforts we have made to further research the process system and improve the reliability of main engine, the running rate of roller crusher system has come to the level of ball mill system. The mature roller crusher technology has injected new vitality to the grinding system.

Roller crusher application
Roll crusher have the advantage of producing an end-product that is has a fine size distribution and they produce little dust or fines during operation. They are widely used for crushing minerals whose abrasive levels are low and in the small scale production of mine. Roll crushers are mostly used during coal mining. The roller crusher can crush materials that in middle hardness such as rocks, ore, coke, lump coal, slag, scoria, fireproof materials, and building materials and so on.
Roller crusher main features and benefits
- 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.

Roller Crusher Working Principle
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 crusher. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.

Note: This specification is just reference, any changes are subject to the roller crusher products.
