Product introduction

The twin-roll crusher, also known as the double-roll crusher, twin-roll machine, or double-roll crusher, is used for medium and fine crushing of raw materials, such as coal, coal gangue, coke, limestone, sulfur ores, phosphate ores, etc. Its crushing method is twin-roll compression.

The twin-roll crusher is widely used in the fields of mineral processing, chemical industry, cement, refractory materials, abrasive materials, and building materials, especially in the building materials industry for crushing products like gypsum stone and mung bean sand, achieving better results than ordinary crushing machinery.

Working principle

1. The double-roll crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices, etc.

2. Adjustment of the output particle size: A wedge-shaped or pad adjusting device is installed between the two rollers. The top of the wedge-shaped device is equipped with an adjusting bolt. When the adjusting bolt pulls the wedge upward, the movable roller will be lifted away from the fixed roller, that is, the gap between the two rollers becomes larger, and the output particle size becomes larger. When the wedge is pulled downward, the movable roller will have a smaller gap under the action of the pressing spring, and the output particle size becomes smaller.

3. The driving mechanism consists of an electric motor, which is driven to the slot wheel through a V-belt to rotate the rollers in opposite directions.

4. For safety, the transmission part should be installed with a safety cover according to the actual situation.

Product features

1. The double-roll crusher has a long service life and is not prone to damage.

2. The double-roll crusher has a compact structure, is lightweight and has a small volume.

3. The double-roll crusher has a simple structure, occupies little space and is convenient for operation and maintenance.

4. The double-roll crusher has a simple and reasonable structure, low operating costs, stable operation, high efficiency and energy saving, and high crushing efficiency.

5. The double-roll crusher is equipped with a dust-proof plate inside, which has good sealing performance and avoids the splashing of fine materials after crushing.

6. The output particle size of the double-roll crusher can be adjusted. After adjusting the roller gap according to the requirements of the crushing particle size, the crushed particle size can be controlled and discharged from the bottom of the crushing chamber with the same particle size.
