In many locations, mills operate during off-peak hours when utilities have surplus power generating capacity and the price of electricity is less. This compares very favourably with energy consumption of global steel production by all methods estimated at some 20 GJ per tonne [10] (1 gigajoule is equal to approximately 270 kWh).

Feb 01, 2021 Literature showed that using VRM instead of a ball mill could reduce Zinc grinding power consumption from 20.11 to 11.11 kWh/t of raw materials (kWh/1000 kg) .
