A significant drawback of traditional ball mills are significant energy losses due to heating of grinding media (up to 80%), mill vibration, noise, wear of the inside mill equipment and balls, etc. [7]. This leads to a significant decrease in the ball mill output and the overspending of the energy consumed by the ball mill.

Therefore, changes in circulating load on a single stage mill may affect the size of the slurry pool and consequently the power draw. Load indication is also very important for high ball charge SAG mills or Run of Mine (ROM) ball mills as changes in power draw resulting from changes in load may be starting point for ball mill media and solids charging generally starts as ...

Circulating Load Ratio Circulating load ratio (CLR) is defined as the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Therefore, the value calculated should determine the number of passes through the mill needed to generate the total amount of new circuitm product.
