Hydrocyclone is a kind of equipment that uses centrifugal force to separate materials. After research in recent years, it has been widely used in various industries such as mineral processing, coal preparation, and chemistry. 1. Classification in the grinding circulation system: the hydrocyclone can be used for the classification of the coarse sand and overflow of the ball mill, as well as the pre-classification before the grinding operation. The obtained process index is roughly the same as that of the mechanical classifier, and can basically replace the classification machine work. 2. Desliming operation: The hydrocyclone can be used for desliming operations of various metal ore and non-metallic ores, and can achieve the following purposes: as a preparatory operation before the sorting operation, improve the sorting index; Flotation agent; removal of coarse sand in non-metallic ore; final concentrate. 3. Concentration operation: In some processes, because the pulp concentration is to...
