Scale Up in Sizing for Grinding Mills. Scale-up criterion is the net specific power consumption i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill specific power is multiplied by the feed rate to get the net mill power.

Currently best examples of ball drum mills in cement. . Power. kW. Raw grinding. Raw mill fan. 490 000. 11 500. 2500. 430 000 .. each cement mill system there is a .

Specific power consumption decreases by about 10. Reductions in specific energy consumption in the range of 7-24 kWht-cement are reported LBNL 2008 Power consumption per ton of cement can be reduced by 8 12 kWh representing 15 to 30 saving over a traditional ball mill system. System output can be increased by more than 100.

The average Bond Ball Work Index for the 2019 master composite was 17.1 kWh per mt. The study showed that on a per-ton basis comminution circuit operating costs could be reduced by approximately 30. Savings are driven by reduced costs for steel and lower power consumption.

Continuous ball mill with low energy consumption. The continuous grinding mode requires higher temperature of the barrel. Such temperature condition and dynamic pulping mode reduce the viscosity of the material after grinding reduce water consumption and material evaporation and reduce power consumption.
