Lifters are placed on the internal walls of the mill and are designed to lift the grinding media (balls) to a higher position. In the calculation of energy consumption in ball mills, classical theories mainly consider factors like the charge fill level, lifter dimensions, the number of lifters, and the rotational speed of the mill.
