Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
It seems from the above that each application will be specific and will require a specific analysis. Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills.

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.
