    Optimization of mill performance by using · PDF file

    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.
