Double Teeth Roll Crusher

Double Teeth Roll Crusher
Feeding size:
<25mm
Processing capacity:
15-50t/h
Applicable materials:
Used for medium and finely crushed materials with soft or medium hardness such as coal, coke, limestone, etc.
Product Description

Roll crusher is also called double roll crusher, double teeth roll crusher etc. The surface of roller crusher are made of high manganese steel, which can stand up to heat treatment. Double roller crusher is suitable for rough and intermediate crushing of brittle materials in such industries as cement, chemical industry, electric power, mine, building materials and metallurgy. The grain size of the input material is large, the particle size of the output product can be controlled, and it is possible to effectively destroy the material whose compressive strength is less than 160 MPa.

Double Teeth Roll Crusher

The crushed material falls from the feed port to the space between the two rollers. After crushing, the final product falls naturally. When there are materials that are too hard or cannot be crushed, the rolls of the roller crusher will automatically withdraw under the action of hydraulic cylinders or springs, increasing the gap between the rolls, and falling of materials that are too hard or that cannot be crushed. So as to protect the machine from damage. There is a certain gap between two rollers rotating in opposite directions. By changing this gap, the maximum output particle size of the final product can be controlled.

 

Working Principle

There is a wedge-shaped or gasket adjustment device between the two rollers, and on the top of the wedge-shaped device, there is an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will lift the movable roller from the fixed roller, so that the gap between the two rollers will become large, and the discharging granularity will become large. When the wedge goes down, under effect of the pressure spring, the gap between the two rollers will become small, and the discharging granularity will become small. The gasket device adjusts the discharging granularity through increasing and decreasing the number or thickness of the gasket, and when the number of the gasket increases, the gap between the two rollers will become large and the discharging granularity will become large; when the number of the gasket decreases, the gap between the two rollers will become large and the discharging granularity will become small.

Four roll crusher

Product Advantages


1.The rollers is wear-resisting chromium molybdenum copper alloy with long service.

2.The gap between the rollers is adjustable, so that the output size and capacity will be changed accordingly.

3.This crusher is equipped with motorless scraper. When the raw material has high moisture content, it can avoid to affect the output size and avoid sticking the roller or blocking the machinehe.

4.According to requirement, it could be in flat roller or toothed roller
