Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

As semiautogenous (SAG) mills become increasingly larger in size, the design of SAG mill liners has been more and more important, and the appropriate liners would enhance mill efficiency and performance. The replaceable liners are mounted inside the mill and exposed to media and/or the material being ground.

Therefore, SAG mills are favored by large mines and are becoming more and more widely used in the mineral processing industry [1,2]. A SAG mill has low speed and heavy load, which cause the energy consumption of grinding operation to be very high. It accounts for a large proportion of the electrical consumption across the plant .
