Grinding Mills and Their Types – IspatGuru

Tumbling autogenous (AG) mills are drum mills which consist of horizontally rotating slightly inclined cylinders of large diameter and small length and fitted with lifting bars. Coarse feed is entering the mill from one end and outlet is at the other end. In the mill, the feedstock is lifted and then allowed to drop through a significant height.

Rod mills, how they function - Mine Engineer

The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge ...

Experimental Study of Charge Motion in a Tumbling Ball Mill

Tumbling ball mills are a common comminution device in the mineral industry processing, wherein the particle size reduction is performed by action of the grinding media. Different forms of transverse motion in a rotating cylinder have been studied by many researchers. The aim of this paper was to study the transitional phenomena between cascading, cataracting and …

SAG Mill - Semi-Autogenous Grinding Mill

A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently, causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load. The liners are replaced as they wear and the lifting action has degraded.
