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 mills working efficiency and product quality during the operation. In this article, we will discuss the measures that can improve the ball mills performance.
closed or open circuit grinding systems. In recent days, the Ball mill grinding systems are used with the Roller press and it is developing very fastly. The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production.

Jun 11, 2020 1 Introduction Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding i.e. its capacity to produce the desired final product.
The efficiency of the early stages of grinding in a Closed Circuit Ball Mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then are being separated, and the coarse part being returned to the mill inlet.
