Jul 08, 2019 The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem.Mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential.

Why Gold Mines Are Adopting Hpgrs To Increase Production
