Double-roll crusher (also known as double-roll crusher, double-roll crusher, double-roll crusher, and double-roller) is used for mineral processing, chemical industry, cement, refractory materials, abrasives, building materials and other industrial sectors, fine crushing high. Used for ores, rocks and refractory materials below medium hardness. Especially in the refractory and mining industries, it has better effects than general crushing machinery. In recent years, it has also been widely used in industries such as steel grit crushing.
This series of double-roll crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. The adjustment of the discharging granularity: there is a wedge or gasket adjustment device between the two rollers, and an adjustment bolt is installed on the top of the wedge device. 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 discharging granularity becomes larger. When the wedge is downward, the gap between the two wheels of the movable roller becomes smaller under the action of the compression spring, and the discharging granularity becomes smaller. The shim device adjusts the discharge particle size by increasing or decreasing the number or thickness of the shim. When the shim is increased, the gap between the two rollers becomes larger, and when the shim is reduced, the gap between the two rollers becomes smaller and the output particle size becomes smaller. . The driving mechanism is composed of two motors, which are driven by a V-belt to the pulley to drag the roller, and rotate according to the relative direction. When crushing the material, the material passes through the roller from the feed port, and is crushed by rolling, and the crushed product is discharged from under the chassis. For safety, the transmission part should install the safety cover by itself according to the actual situation.
