What is the difference between a SAG mill and ball mill?

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. A SAG mill with a 44′ (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles.

The advantages of composite mill liners The Weir

2020-5-28  Advantage #3 Composite liners have a shorter delivery time. Due to the high production loss experienced every time a mill is shutdown, it’s critical that mill liner deliveries are consistently on time to allow for inspection and preparation ahead of the mill stoppage. Composites are quicker to manufacture, which results in shorter lead times.
