JKSimMet was used to fit a model to site DCS data. Thus, there was considerable scope to reduce the ball-mill power consumption by using smaller ball-mill grinding media. However, for a final grind of 75 μm, the reported power values for both HPGR-ball mill and SABC circuits were based on JKSimMet modeling alone.

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.

It is also possible to use the −1″ fraction that shows a positive effect on the SAG mill throughput (the power consumption decreases, but the specific energy decreases more) because the mineral goes faster to the mill discharge, leaving a greater part of the grinding task to the secondary ball mills.

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.

Extensive operational trials on industrial combined grinding plants have shown that the specific energy consumption of the ball mill can be lowered …

United States power consumption is related to comminution (Comminution and Energy Consumption, 1981). With this in I mind it is understandable that one would want to control a grinding circuit so that the energy required to process a given ton of ore is optimal. .Furthermore, overgrinding an ore and the subsequent production of fines can reduce the

The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun, 2009).

3) The specific feed capacity of a vibrating mill exceeds that of a ball mill by a factor of 19.4 and is 17.5 and 12.5 times higher in the classes of less than 125 and 74 μm, respectively. The energy consumption when grinding metal chips in a vibrating mill is 1.64 times lower than that in a ball mill.

The power draw may be 4% - 10%. less with classifying liners due to the lower friction. To draw the same power they require a higher. volume loading which requires more grinding media, reduced mill air velocity and can result in. reverse classification if the volume loading is too high. This means that the full mill power potential
