10%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.

by Means of Closed Mill Circuit Modeling. (December 2007) Gleb Gennadievich Mejeoumov, B.S., Ivanovo State Power University, Russia; M.S., Ivanovo State Power University, Russia Chair of Advisory Committee: Dr. Dan Zollinger Grinding of clinker is the last and most energy-consuming stage of the cement

The reported SABC circuit power for the 160 μm grind size was based on actual site data. 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 ...

On the class of work for which it is especially suitable the power consumption of a rod mill is about three-quarters that of a ball mill with the production of less undersize. The rod and liner consumption is also about 75% of that of a ball mill, and rods cost less than balls because they are more easily manufactured.

lower energy consumption. In ball mills, smaller grinding media versus 25 mm media generate a power saving from 10% to 44%. In vertical stirred mills, the power saving increases from 20% to 60%. More potential savings have been identified. For the same operating conditions, how a vertical stirred mill is performing compared to ball milling?
