Working principle of double teethed roll crusher:

Double teethed roll crusher is fixed with two wear- resistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the materials. The materials enter the space between the two rolls, suffered both extrusion and shear force. In the crowd rolling, cutting and grinding, they are crushed into the required size and then discharge from bottom.

Application of Double teethed roll crusher:

Double teethed roll crusher is suitable for coarse and medium crushing crisp and massive materials in the cement, chemistry, power station, mines, metallurgy, building materials, refractory and coal mines and other industries. The material feeding granularity is very big and the material discharging granularity is adjustable, and it is able to crush materials with compression strength less than 160MPa. It is ideal for especially the coal industry because when using this machine to crush the raw coal, the coal can be directly crushed after deironing and decontaminating.

Features of Double teethed roll crusher:

♦ Simple and stable operation.

♦ Low noise, Less dust and uniform particle size.

♦ Large crushing ratio, high production efficiency.

♦ Simple structure, small volume, light weight, large capacity, low production cost low, and high crushing cavity.

♦ Crushing along the ore joint surface, less power consumption, and high efficiency.
