This article is about the methods and equipment being used in the first step of slime water system, which is called fine particle classification. With the development of automation in coal mining and preparation, fine particles in the raw coal increases substantially. The fine coal preparation is mainly completed in water, which makes the slime water system face to a heavier load.
