The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size. A pilot plant investigation with an overflow mill discharge has been conducted. For a given throughput, it seems that the pool size has a major influence on the product grind.

mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.

Effect Of Grinding Media On Sag Mill Performance. Lack of grinding media in the SAG mill will result in high circulating loads which can result in slurry pool formation due to grate and pulp lifter restrictions further adversely affecting circuit performance. Achieving fine grind sizes in single stage mills has typically required operation of an AG mill to provide adequate grinding .

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working animal (, horse mill), wind or water ().

· Ball mill: When the particle size of the product is less than, the grinding effect of the ball mill is greater than that of a rod mill of the same specifiion. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
