Roll Crusher

Introduction:Roll crusher is also called double roll crusher, roller crusher, double roller crusher, smooth roll crusher and toothed-roll crusher, which can crush adhesional wetting materials.

Roll Crusher Overview

Roll crusher is also called double roll crusher, roller crusher, double roller crusher, smooth roll crusher and toothed-roll crusher, which can crush adhesional wetting materials. The machine has strict requirements for particle and shapes, so it is widely used in chemical, coal, coking and so on.Hongji Mine Machinery can provide you with not only the roller crusher and all of accessories, but also type selection introduction and installation guidance, etc.

Roll crusher can be referred to as compression-type crushers. In the mining industry, they are used to crush mines of medium or low hardness, rocks that have low or medium rigidity during mine selection, for cement, chemicals, and industrial production of building materials, among others. Its effect is more excellent than common crushing equipment.

Features and Applications of Roller Crusher

Roll crusher has the advantage of producing an end-product that is has a fine size distribution and they produce little dust or fines during operation. It is widely used for crushing minerals whose abrasive levels are low and in the small scale production of mine. Roll crushers are mostly used during coal mining. The crushers used may either be single roll or double roll. When used in coal mining, the surface of the rolls will have teeth or raised forms (when used for mineral and metal ores, the rolls have a smooth surface).

The structure of Roll Structure

The structure of Roll Structure

This series roll structure is composed of rollers, adjustment and drive device.

The working principle of Roll Crusher

Adjustment of discharging granularity: There is wedge or gasket adjustment device between two rollers of roller crusher. The adjusting screw bolts are fixed on the head of wedge head. When the adjusting screw bolts pull the wedge upwards, the wedge makes the roller be apart from fixed pulley. The gap between the two rollers becomes bigger and then the discharging granularity becomes bigger. When the wedge goes downwards, the gap of the two wedges becomes smaller and then the discharging granularity becomes smaller. Gasket device adjusts the granularity by decreasing and increasing the gasket numbers or thickness. When the gasket number increases ,the gap of two rollers and granularity become bigger, on the other hand ,the gap and granulariyt become smaller.
