Ball Mills - an overview ScienceDirect Topics www.sciencedirect.com topics engineeringA feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages: Breaking down energy consumption in industrial grinding mills www.researchgate.net publi ion 315148304It is generally accepted that the energy required to produce new mineral surfaces is less than 1% of the electricity consumed to operate ball mills. The remaining 99% is assumed to be dissipated The power consumption calculation of a ball drum mill www.researchgate.net publi ion 311934663 TheBall drum mills area commonplace in grinding offerrous and non-ferrous metals, and a cement production in the world.
