What’s a Roll Crusher?

Roller crusher is also known as roll crusher, which relies on the high-speed rotation of roll wheel to crush materials. The commonly used roll crusher types include double roller crusher, toothed roller crusher, four roller crusher, etc.

Working Principle Of Roll Crusher

A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

Advantages Of Roll Crusher

The particle size of the crushed material is uniform, the over-crushing rate is low, the maintenance is convenient, safe and reliable;
Simple structure, small footprint, easy operation and maintenance. Made of high wear-resistant materials;
Low maintenance cost, low noise, less dust;
Excellent running performance, high energy and energy saving, green and low carbon.
