There are efficiency factors for dry grinding, open circuit ball milling, mill diameter,.energy used in ball mill cement grinding,Finish Grinding | Industrial Efficiency Technology & MeasuresFinish grinding accounts for nearly 40% of the electricity use in cement production. (ECRA, 2009). Ball mills continue to be the dominating choice for finish grinding, although their share has decreased from 59% in 2000 to 49% in 2007. On the other hand, vertical roller mills (VRM) are increasingly used for finish grinding.How to Make Milling More Energy Efficient - Semantic Scholarstep is to grind the clinker in a ball mill equipped with steel balls of varying sizes. depending on the type of cement, other materials such as granulated blast furnace slag can be added at the grinding stage. The mill control can be opti- mized based on predicted quality parameters, which in turn reduce energy consumption.

Cement mill - Wikipedia

These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption.

Energy Efficiency Improvement and Cost Saving Opportunities for .

(COWIconsult et al., 1993). Traditionally, ball mills are used in finish grinding, while many plants use vertical roller mills. In ball or tube mills, the clinker and gypsum are fed into one end of a horizontal cylinder and partially ground cement exits from the other end. Modern ball mills may use between 32 and. 37 kWh/tonne (29.
