What is the significance of grading operations in the grinding cycle?

Grading operations play an important role in the grinding cycle. Because the useful minerals of fine-grained inlays are to be dissociated and sorted, the ore must be ground to a certain degree of fineness. However, it is necessary to avoid over-grinding and prevent the adverse effects of muddy on the sorting process. This requires that the part of the grinding product that is qualified in the fine-grained product be separated in time to avoid unnecessary grinding and early delivery to the sorting operation. The unqualified part is returned to the mill for re-grinding. It can be seen that the closed-circuit grinding cycle with grading operations is very significant both technically and economically. Currently in mineral processing plant in grading operations are widely used.
