Mining Machinery

Working principle
Hydraulic roller crusher consists of a couple of parallel cylindrical rollers which are fixed horizontally. When these 2 rollers rotate in opposite directions, the fed material fall down to the rollers, and will be brought into the middle of the two rollers by friction and gravity, crushed and grinded by the two rollers and at last broke into small pieces. The crushed stone is pushed by the rotating roller and discharged by gravity.

Features
1. Available for ore dressing, chemical, cement, refractories, abrasive, building materials industries.
2. With the more excellent effect than general stave machinery.
3. Finely crushing all kinds of ore and rock below the high, medium hardness,which can make the minimum grain size below 100 mesh.
4. Stable operation, easy maintenance, low cost and output size adjustable.

Applications
The roller crusher is widely applied in the industries of mining, building materials, chemical industry, metallurgy, etc. The roller 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.
