Features of roller crusher

The roller crusher has the advantages of small size, large crushing ratio, low noise, simple structure, and convenient maintenance.

The roller crusher is suitable for coal, metallurgy, mining, chemical, building materials, and other industries, and is more suitable for the crushing of raw coal in large coal mines or coal preparation plants.

The roller crusher has a large crushing capacity. The motor and the reducer are connected by a distance-limited hydraulic coupling to prevent power overload and sensor overload protection, which is safe and reliable.

The spacing of the gear rollers is hydraulically adjusted, and the gear roller bearings are lubricated centrally.

Optimized design of tooth shape, selective crushing of tensile and shear forces, high efficiency and low consumption, and uniform granulation.

Features of Roller Crusher

1. 1. The roller crusher has a simple structure, small footprint, and convenient operation and maintenance. The interior is equipped with a dust-proof plate, which has good sealing performance and avoids the splashing of small materials after crushing, with less dust, and the working environment is greatly improved. The abrasive roll body is re-optimized design, and the equipment does not need to be replaced for life.
2. 2. With compact structure, light weight and small volume, compared to the grinding series with the same production capacity, the roller crusher can significantly save investment.
3. 3. Simple structure, small footprint, convenient operation and maintenance.
4. 4. The interior is equipped with a dust-proof plate, which has good sealing performance and avoids the splashing of small materials after crushing, with less dust and low working noise.

Structure and composition of roller crusher

The roller crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices.

Matters needing attention in the work of roller crusher

1. 1. It is necessary to strengthen the iron removal work for the mine. Non-crushing objects (bits, etc.) falling into the pair of rollers will damage the crusher, resulting in a parking accident. Therefore, an iron removal device should be installed before the crusher.
2. 2. The viscous material is easy to block the crushing space. It should be stopped to deal with the blockage failure, and it is not allowed to smash the ore during operation.
3. 3. When the material processed by the roller crusher contains a lot of large pieces, it should be noted that the large pieces of ore are easily squeezed out from the crushing space to prevent injury to people or damage to the equipment.
4. 4. After the roller crusher runs for a long time, due to the large wear of the roller surface, the particle size of the product will be too fine. At this time, attention should be paid to adjusting the discharge port or overhauling the equipment.
5. 5. Strengthen the inspection of the parts of the roller crusher, and refuel the lubricating parts of the crusher on time to keep the equipment in a good lubrication state.

Working principle

Roller crushers are divided into double-roll crushers, four-roll crushers, and toothed roll crushers. Roll crushers are classified according to their specifications.

The adjustment of the discharge granularity is that 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 pulls the wedge 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 particle size becomes larger.

When the wedge goes down, the gap between the two rollers of the movable roller becomes smaller under the action of the compression spring, and the discharge particle size becomes smaller.

The gasket device adjusts the size of the discharge particle by increasing or decreasing the number or thickness of the gasket.

When the gasket is added, the gap between the two rollers becomes larger, and when the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller.
