The use of finer media also results in reduced energy input probably due to increased " fluidity". These results agree with those reported by Orumwense and Forssberg  for dolomite samples ground in an annular ball mill. Effect of media density. The effect of media density on the grinding of limestone is shown in Table 2.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Outotec HIGmill high intensity grinding mill Outotec
Outotec HIGmill High Intensity Grinding Mill. HIGmill has a less complex and more compact process layout and flow sheet than other stirred media mills. The process comprises just a scalping cyclone, feed tank and pump, and the mill itself. The benefit of high power intensity and vertical installation is a very small footprint.
Stirred Milling VERTIMILL® Grinding Mills & Stirred Media
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.
