the other mills, as previously mentioned ball mills have a very low efficiency in terms of utilizing the energy generated towards particle size reduction. The diameter of the balls used in ball mills play a significant role in the improvement and optimization of the efficiency of the mill [4]. The optimum rotation speed of a mill, which is the
In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a “dropped” state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. 1. If the rotating speed is low, the ball in the ball mill
