The scrubber is a high-concentration and powerful stirring and scrubbing equipment. It is suitable for use in various industry departments such as metallurgy, chemical engineering, building materials, light industry, food, and pharmaceuticals, and is used to clean the surface of materials. Through scrubbing and the friction between materials, the dirt, impurities and their oxides on the surface of the materials can be removed, thus forming a fresh surface for the materials. To facilitate the reaction of materials in the next technological process. This machine is particularly suitable for the mineral processing process. The materials that have been scrubbed are conducive to the flotation, beneficiation and re-capture. It can increase the recovery rate of mineral processing operations. For high-concentration pulp, the scrubbing effect is even more remarkable.
