The double smooth roll crusher can be used for finely crushing various high and medium hardness ores and rocks in the industrial sectors such as mineral processing, chemical industry, cement, refractory materials, abrasives, building materials, etc., especially for the production of guar and mung beans in the building materials industry. Products such as sand have better effects than general crushing machinery.
When working, the crushed material will fall between the two rollers through the feeding port for squeezing and crushing, and the finished product will be discharged from the lower end of the discharging port. There is a wedge or gasket adjusting device between the two rollers of the roller crusher. There is an adjusting bolt at the top of the wedge device. When the adjusting bolt block is pulled up, the wedge will push the movable roller away from the fixed wheel, which is the two rollers. The gap 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 discharge particle size becomes smaller. The shim device adjusts the discharge particle size by increasing or decreasing the quantity or thickness. When the shim is added, the gap between the two rollers becomes larger, and when the shim is reduced, the gap becomes smaller.
