The roller crusher (double roll crusher) is suitable for coarse and medium-sized crushing of brittle block materials in cement, chemical, electric power, mining, metallurgy, building materials, refractory materials, coal mines, etc., and its feed size is large, and the discharge granularity Adjustable, it can crush materials with compressive strength ≤160MPa. Especially in the coal industry, the use of this machine to crush raw coal, as long as the iron removal, impurity removal, no need to remove the sputum, can be directly broken, the broken material, uniform particle size, low crush rate, which simplifies the coal preparation process and reduces Investment and production costs.
The series of roller crushers (double roll crushers) are mainly composed of roller components, roller support bearings, pressing and adjusting devices and driving devices.
Adjustment of the discharge granularity: a wedge or washer adjustment device is arranged between the two rollers, and the top end of the wedge device is provided with an adjustment bolt. When the adjustment bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheel. That is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge is downward, the two rollers of the movable roller become smaller under the action of the pressing spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the discharge by increasing or decreasing the number or thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge granularity becomes smaller. . The driving mechanism is driven by two motors, which are driven by a V-belt to the sheave of the sheave and rotate in the opposite direction. When the material is crushed, the material passes through the roller from the feed port and is crushed by rolling, and the broken product is discharged from the bottom of the chassis.
