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

the trend in large SAG mills has been to use wide-spaced shell lifters with large lifter face angles, primarily to reduce packing and ball/liner damage, and to use larger, hence fewer, mill liner parts to reduce downtime at liner change-outs. Key words: Comminution, Grinding, SAG mill, Mill liners Paper number MMP-07-002.

ATTRITOR GRINDING MILLS AND NEW …

which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
