Double-roller crusher (2-roller crusher) is used to process mid-hard materials in the cement, chemical, electric, metallurgical, building materials, fireproof material, etc, industries.

Such as: crushing limestone, slag, coke, coal, etc, these mid-hard materials secondly and finely.

This series of 2-roller crushers are mainly consisted of roller wheel, roller wheel supporting bearings, regulation device and driving device and so on.

 

Adjustable output granularity: There are wedge-shaped or gasket regulating device between the two rollers, the top of wedge-shaped device is adjustment bolt. The wedge tips active roller away from the fixed wheel when adjustment bolt pulls wedge upward. At this time, up, wedge will the space between the two rollers becomes larger, output granularity becomes larger. When the wedge is down, the gap of the two active rollers becomes smaller under the action of the compressing spring, particle size becomes smaller. Gasket regulating device adjusts the size of particle through increasing or decreasing the quantity or thickness of pads. The gap of two rollers becomes large when increasing gasket. The gap of the two rollers becomes smaller when reducing gasket output granularity becomes smaller.
