Efficient crushing of coke/coal gangue by roller crusher in coal laboratory

Efficient crushing of coke/coal gangue by roller crusher in coal laboratory

Roll crushers are mainly used for intermediate and fine crushing of raw materials. Crushing of materials such as coal, gangue, coke, limestone, sulfur ore, phosphate ore, etc. Its crushing method is roller squeezing. The crushed material should be brittle, and the shape of the crushed material is mostly regular flakes. The compressive strength of the crushed material should not exceed 60MPa, and it should have a hardness of level 3. If the moisture content of the material exceeds 6%, particle bonding will occur.

Efficient crushing of coke/coal gangue by roller crusher in coal laboratoryWorking principle and structural characteristics:

1. The machine crushing system is equipped with a pair of counter rotating pressure rollers. During operation, the material is quantitatively fed from the hopper and enters the middle of the rollers in a tangential direction. The material is crushed, and the crushed material enters the bottom discharge hopper of the machine, completing the crushing process.

2. The particle size is achieved by adjusting the gap between the rollers, which is easy and convenient. The roller is made of carbon steel and has undergone heat treatment, with moderate hardness.

3. The design structure of this machine is reasonable, easy to maintain, and easy to operate. Sealed design, no pollution. It has been widely used in sampling and testing in industries such as coal, coking, mining, and metal smelting.
