Introduction
Roller crusher knife, also known as roller crusher, belongs to traditional crushing equipment. It is mainly used for fine processing of material particles. As the main working part, the two cylindrical rollers rotate oppositely to achieve the purpose of crushing. Due to its peculiar tooth crushing structure, it is also called Teeth Roll Crusher.

Working principle
Through the inlet, the raw material falls between two rolls and after crushing, the final product falls naturally. When there is material that cannot be crushed or material is too hard, the rolls of the Roller Crusher Knife automatically give way under the action of spring and hydraulic pressure to widen the gap between the rolls so that the hard or cannot be crushed to avoid damaging the machine.
The gap between the two rolls can be adjusted to change the size of the final product.
Physical structure of double roll crusher
1.This series double roll crusher mainly consists of rolls, roll support bearings, pressure and regulating device and driving parts.
2. Through the inlet, the raw material falls between the two rolls, and after crushing, the final product falls naturally. When there is material that can't be crushed or material is too hard, under the action of spring and hydraulic pressure, the rolls will automatically give way and expand the gap between the rolls so that the hard or can't be crushed to avoid damaging the machine. The gap between the two rolls can be adjusted to change the size of the final product.
3. Roller Crusher Knife can adjust the gap between rolls and transmission by triangle belt or multi-way coupling, while four roll crusher is only adjusted by triangle belt.
4. For safety reasons, the drive part should be installed with safety cover according to the actual situation.
Features of double roll crusher
