Classification of Grinding Products

Classification of grinding products is a process of dividing the grinding products of wide particle size into numerous products of narrow particle size, which is based on the difference of the settling speed of the ore grinding product particles in the medium. It is a significant preparation operation of the mineral processing plant. In the classification process, the particles with large size or high density generally settle down quickly and enter the lower part of medium, which is called “underflow” or “grit settling.” The particles of small size or low density mostly flow out from the upper part of medium with the fluid, which is called “overflow.”

Classification

The medium used for classification of grinding products includes air and water. When air is used as classification medium, it is called dry classification, and when water is used as classification medium, it is called wet classification. According to the different operation purposes and equipment, wet classification is...
