A pilotscale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of % was observed for the dry VRM compared to the wet ball mill (% for the circuit).
