Roller crusher, mining processing machinery

The double-roller crusher (double-roller crusher) is suitable for coarse and intermediate crushing of brittle block materials in cement, chemical, electric power, mining, metallurgy, building materials, refractory materials, coal mines and other industries. Its input particle size is large and the output particle size is large. Adjustable, can crush materials with compressive strength. Especially in the coal industry, this machine is used to crush raw coal, which can be directly crushed as long as it removes iron and impurities without gangue removal. The crushed materials have uniform particle size and a low over-crushing rate, thus simplifying the coal preparation process and reducing the cost. investment and production costs.
Performance characteristics of double-roller crusher:
This series of double-roller crusher (double-roller crusher) is mainly composed of rollers, roller support bearings, compression and adjustment devices, and driving devices. .
Working principle of double roller crusher:
Adjustment of discharge granularity: A wedge or gasket adjustment device is installed between the two rollers. The top of the wedge device is equipped with an adjustment bolt. When the adjustment bolt moves the wedge When pulled up, 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 moves downward, the gap between the two rollers of the movable roller increases under the action of the compression spring. becomes smaller, the discharge particle size becomes smaller. The gasket device adjusts the discharge granularity by increasing or decreasing the number or thickness of the gaskets. 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 composed of two electric motors, which are driven to the sheaves through a triangle belt to drag the rollers to rotate in relative directions. When crushing materials, the materials pass through the rollers from the feed inlet and are crushed after rolling. The crushed products are discharged from under the bottom frame.
Safety in use of roller crusher:
For safety, the transmission part should install its own safety cover according to the actual situation.
