More ### Effect of lifters and mill speed on particle behaviour

2017-5-1 · Many formulas can be used to calculate the net power of a mill. These formulas come in two basic types: those used when a ball mill works at a relatively low speed and those used when a ball mill works at a relatively high speed. Thus, increasing the lifter number appropriately is a good approach to improve the working efficiency of a ball
