Operation of SAG Mills,Principle Operation of Semi ...

2018-1-25  The motion of charge or rocks and balls in SAG mills can be viewed as a field of breakage generated as a result of the internal profile of the lifters and the rotational speed of the mill shell. The ore entering through the feed port is ground by this field and, after being sufficiently ground to the grate slot size, the slurry leaves through the slots in the grate.

Semi-autogenous grinding (SAG) mill liner design and ...

2016-6-6  Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

Ball Mill Explained - saVRee

Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
