Double roller crusher is mainly used for secondary and fine crushing materials with soft or middle hardness like coal, coke, limestone, clinker mineral, slag, shale and so on. Depending on the requirements, the rolls are smooth or toothed.
Double roller crusher is mainly used for secondary and fine crushing materials with soft or middle hardness like coal, coke, limestone, clinker mineral, slag, shale and so on. Depending on the requirements, the rolls are smooth or toothed.
After entering the crusher, the material is crushed by rolling and grinding shear force of the roller. Double roller crusher has feataures of simple compact structure, light body, stable and reliable performance, large crushing ratio.
The roller crusher is driven by two motors full of power. And the most important highlight of roller crusher is the discharge can be adjusted. Users can adjust the crusher according to their own finished material needs.
We produce smooth roller crusher and teeth roller crusher. It needs to choose suitable model according to material features, moisture, crushing ratio, output size, capacity etc.Baichy Machinery could advise suitable crushers for you.
According to requirement, it could be in flat roller or toothed roller.
The rollers is wear-resisting chromium molybdenum copper alloy with long service.
This crusher is equipped with motorless scraper. When the raw material has high moisture content,
The gap between the rollers is adjustable, so that the output size and capacity will be changed accordingly.
The materials to be crushed fall from the feeding mouth to the space between the two rolls.After being squeezed and crushed, the final products will naturally fall. When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall down.Thus protecting the machine from being damaged. There is a certain gap between the two rolls that rotate at the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap. Double roller crusher’s the materials by relying on the two round rollers rotating at the opposite direction, and four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating at the opposite direction.
