Crushing

Overview

The (double) roller crusher is suitable for medium crushing and fine crushing operations of solid materials with compressive strength less than 300Mpa and moisture content of less than 35%, and can be widely used in mining, thermoelectric, cement ceramics, metallurgy, chemical, building materials and other industries, with the characteristics of low maintenance cost, reliable performance, less dust, and low noise.
The (double) roller crusher is equipped with two crushing rollers, according to the particle size required by the user, the roller surface is divided into two forms: flat roller surface and welding surfacing roller surface, if the compressive strength of the material exceeds 200Mpa, the weighting model can be selected.
The flat roller surface model is suitable for fine crushing operations with a feed particle size of less than 80mm and a finished product particle size of 0.5-10mm. For example, using pebbles and construction waste to make sand (sand); mining fine crushed iron ore, quartz stone; Crushing raw materials in the ceramic industry; crushing coke and quicklime in the metallurgical industry; coking plant fine crushed coal powder and coke powder; The chemical industry crushes various raw materials, etc. or similar crushing occasions mentioned above.
The overlay roller surface model is suitable for medium and fine crushing operations with feed particle size less than 150mm and finished product particle size requirements of 5-30mm. For example, cement clinker, limestone and composite materials are pre-crushed before mills in the cement industry; pre-crushed coal before grinding in the water and coal slurry industry; pre-crushing steel slag, iron ore and silica ore before grinding in the iron ore industry; brick factory crushes various ores to make non-burning bricks; crushing thermal coal in thermal power plants; Or a similar crushing occasion as above.

Working Principle

The pair (double) roller crusher is the use of two high-strength wear-resistant alloy crushing rollers, the high extrusive force generated by the relative rotation to crush the material, after the material enters the gap between the two rollers (V-shaped crushing chamber), it is affected by the extrusion force and shear force of the relative rotation of the two crushing rollers, and the material is crushed into the required particle size and discharged from the discharge port under extrusion, shearing and grinding.
