We may infer from this experiment that a ball mill with a rotational speed of 45 rpm is more effective than one with a rotational speed of 100 rpm. This is because the kinetic energy of the balls increases as they travel further, resulting in a larger impact that causes more suitable contact, which provides enough energy to smash the large ...
