[0002] Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because it is white and delicate, it is also called dolomite. The pure kaolin is white, delicate and soft, and has good physical and chemical properties such as plasticity and refractoriness. Its mineral composition mainly consists of minerals such as kaolinite, halloysite, hydromica, illite, montmorillonite, quartz and feldspar. When processing kaolin, a pulping mechanism is needed, and filtration is a process in the pulping process. However, it is not convenient to clean the surface of the screening mesh comprehensively during the filtration and screening operation, resulting in gravel blocking the screening mesh and affecting the subsequent filtration operation.
