Introduction:

Rock roller crusher is mainly used for the crushing of medium-hard mines and rocks in cement, chemical, electric power, metallurgy, building materials, refractories and other industrial sectors, such as the secondary crushing and fine crushing of limestone, slag, coke, coal and other materials.Roller crusher is mainly made up of roller wheels, roller support bearings, clamping and regulation devices and drive devices.

Working principle:

Roller crushers have a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roller crushers will only crush materials down to a minimum particle size of about 10 Mesh (2 mm). A crushes using compression, with two rollers rotating about a shaft, towards the gap between the rollers. The gap between the rollers is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.
