• Breaking down energy consumption in

    The grinding process in ball mills is notoriously known to be highly inefficient: only 1 to 2% of the inputted electrical energy serves for creating new surfaces.Breaking Down Energy Consumption in Industry Grinding ,2022-3-7 · It 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 as noise, vibration, and heat, but there is no clear picture on how much is lost in the air or serves to heat the slurry.
