The ball mill specific power consumption E ball is determined by deducting a cone crushing component from the Bond Rowland E ssbm specific power consumption. See the base formulae in the Bond SSBM model. where CF is the Essbm calibration factor (in the Circuit Settings).
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.
A feature of ball mills is their high specific energy consumption a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.
Dec 18, 2013 This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.
Ball consumption varies with the fineness of the product, hardness of the ore, quality of ball, and whether a mill is run in closed or open circuit. The ball, consumption for mills delivering a coarse product, all passing 8 mesh and containing 10 to 20 per cent. below 200 mesh, the mill.
