We know that an appropriate increase in the number of revolutions of the mill can increase the productivity of the mill, but it cannot be unilaterally pursued with high number of revolutions. Because of the increase in the number of revolutions, there will be some problems. For example, the current
ball mills are designed and manufactured according to the theoretical critical number of revolutions. If the critical number of revolutions or supercritical revolutions are used, the mill will lose the grinding effect due to the centrifugal force; the second is due to High-speed motion increases mechanical vibration and component wear, and equipment life is greatly reduced. At the same time, the internal grinding effect of the ball mill is destroyed, the ore discharge becomes thicker, and the grading load is increased, so that the product does not meet the qualified grain size requirements. Moreover, the wear of grinding media and liners is greatly increased.
So, instead of running most critical rotation speed beneficiation plant used in operating speed.
