The closed-circuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plant. There are many factors that may affect the ball mill's working efficiency and product quality during the operation. In this article, we will discuss the measures that can improve the ball mill's performance.At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill, it leads to mill overload. In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption.

DEFINITON: • A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering etc. 6.
