Ball Mill Optimization in The Cement Grinding Plant

In ball mill applications, ball size distribution is an important parameter. Many literature studies have

revealed that the design to be made affects performance. Mill optimization evaluations are an important

stage to find weak points. A thorough examination of the characteristic features of the current system

and the accuracy of the model approaches used are critical to increasing or optimizing the circuit's

performance. Furthermore, at grinding sizes smaller than 45 microns, the efficiency of the mills

significantly decreases, leading to an excessive increase in energy consumption, which ultimately

renders grinding uneconomical. For this reason, it is very important to make good optimizations. The

study examined how to alter the particle size in the current mill. In addition, similar studies were

conducted on the same mill with a design change, and a comparison was made. The studies led to the

addition of a new ball charge of 220.69 tons to the mill, with a maximum ball size of 25 mm. Despite

working fewer sieves below 32 microns than the previous year, the mill's capacity remained unchanged.

Examining the classifier efficiency revealed a decrease in product escaping into the mill as the separation

particle size increased to 23.68 microns.
