Mill (grinding) Wikipedia
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 ().

the ball mill, but they can also be used as a onestage grinder. The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills. SAG mills of over 40foot diameter have been constructed. Like the ball mill, the AG/SAG mill will have a critical rotation speed above which grinding ceases. Mill motor

Vertimill® Metso
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.

the grinding power required for a given throughput of material under ball mill grinding conditions. It is a ‘locked cycle’ test conducted in closed circuit with a laboratory screen. The closing screen size is selected so that the product P80 from the test is as close as possible to the product P80 expected from the circuit under design.

Grinding Mills an overview ScienceDirect Topics
According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills. In tumbling mills, the mill shell is rotated and motion is imparted to the charge via the mill shell. The grinding medium may be steel rods, balls, or rock itself. Media ball sizes, for example, range from about 20 mm for fine grinding to
Grinding mill power requirements beckersmuehle.de
Scale Up in Sizing for Grinding Mills Scalp criterion is the net specific power consumption ie 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.

Best energy consumption
However, in pure energy efficiency terms, the benefit of grinding power reduction is countered by the very high power required by mill fans. In addition, the absence of the heat generated in a ball mill and the high volume of air required by the vertical mill have required the provision of waste heat from cooler exhausts and/or auxiliary
Optimization of mill performance by using
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to continuously optimize mill operation, it
