Mill (grinding) Wikipedia
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
Grinding Mills: Ball Mill & Rod Mill Design & Parts
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball
Three roll mill Wikipedia
The single-roll mill works by material passing between the roll and a fixed bar pressing against the roll. The five-roll mill incorporates four successively smaller in-running nips and hence, compared to the three-roll mill, allows the use of larger agglomerates as part of the input material- but is correspondingly more complicated and

Ball Mills Mineral Processing & Metallurgy
Working Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill “sees” instantaneously unless some damping system such as a surge hopper is used.
