Roll Crusher
Introduction:
Roll crusher is with reliable operation, easy maintenance, and low cost, adjustable particle size. In accordance with the number of rollers, it can be divided into double roll crusher and four roll crusher. it is widely used in cement, metallurgy, chemical industry, electric power and coal industries and the toughness of brittle materials processing.
Working principle:
The maximum reduction ratio of roll crushers is 4:1. The materials are crushed by compression between two rolls rotating about a shaft. The size between the two rolls used for compression can be suitably adjusted according to the desired size of the end-product.
It is important to note that the largest particle size of the materials inserted should not be more than four times the dimension of the gap. The rotation of the two rolls draws the particles to be crushed into the gap forming a friction angle between the rolls and particles referred to as nip angle. Through forcing the materials between the gaps, the rolls create impressive forces causing the materials to fracture.
Applicable material of roll crusher:
1) Clay
2) Shale clay
3) Coal gangue
4) River silt
Hour output: 150m3/h
