Dec 18, 2013· This quantity is small compared to the power used by asemi-autogenous milland aball millin a primary grinding circuit; aball millcan have an installed power of up to 15 MW, while installed power for aSAG millcan go up to 25 MW. However, theenergyused for fine grinding is still significant.
