Double Roll Crusher

 roll crusher：Suitable for cement, metallurgy, chemical industry, electric power, coal and other industrial departments in crushing all kinds of medium hardness materials, such as limestone, slag, coke, coal and other materials of medium crushing, fine crushing operation. The roller crusher has large crushing capacity, and the motor and the reducer are connected with the limited distance type hydraulic coupling to prevent the power overload, the sensor overload protection, reliable performance. Gear roller spacing hydraulic adjustment, gear roller bearing centralized lubrication. Tooth shape optimization design, pull shear selection crushing, low consumption, uniform grain.

Working principle of roll crusher:  
       Roller crusher is mainly composed of roller, roller supporting bearing, pressing and adjusting device and driving device and other parts. 

Adjustment of discharge size：
       With a wedge or gasket between the two roller adjustment device, adjusting bolt, wedge at the top of the device when the adjusting bolt will wedge pulled up, wedge rolling activity to the top from the fixed wheel, namely two roller clearance greatens, discharging granularity, when the wedge downward, activities under the action of the roller in a compression spring two rounds of smaller clearance, discharge size smaller. The gasket device adjusts the discharge particle size by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller.
