有色金属选矿厂磨矿作业的能量消耗资料表明:铜选厂为7.5～11.5千瓦·时/吨,占全厂总能耗的35～60%;铅-锌多金属选矿为8～21千瓦·时/吨,占全厂总能耗的40～65%;稀有及贵金属选矿厂为10～19.5千瓦·时/吨,占全厂总能耗的50～70%。随着入选矿石品位日益贫化,嵌布粒度变细,磨矿能耗仍有大幅度上升的可能。罗马登、H.卢帕夫、K.特卡罗娃以及C.C.哈里斯等人研究了磨机内能量利用的情况,从各自的角度出发,深入分析了 The energy consumption data of non-ferrous concentrator grinding operations show that the copper processing plant is 7.5 ~ 11.5 kWh / t, accounting for 35-60% of the total energy consumption of the plant; the lead-zinc polymetallic concentrating is 8-21 kW · Hour / ton, accounting for 40 ~ 65% of the total energy consumption of the whole plant; rare and precious metal concentrator is 10 ~ 19.5 kWh / ton, accounting for 50 ~ 70% of the total energy consumption of the whole plant. As the grade of the beneficiated ore becomes more and more depleted, the grain size of the inlay will be thinner, and the energy consumption of grinding will still be greatly increased. Romeo, H. Luparv, K. Tekarova, and C. C. Harris et al. Studied the energy utilization in a mill and, from each point of view,
