Coal Mill an overview ScienceDirect Topics

Within the Classifier, oversized coal particles are separated from the Product (P) coal (PF) It has to be mentioned that the number of balls is increased during the mill operation. For example, the initial ten balls, after lowering the diameter below some value (due to wear), is complemented with the 11 th additional ball. If the existing pulverizer is equipped with 6 or 7 balls
