Grinding efficiency is a critical factor in the performance of the fly ash ball mill. The grinding efficiency of the ball mill is determined by several factors, including the size of the grinding media, the feed rate, and the speed of the mill. The higher the grinding efficiency, the more fly ash can be ground in a shorter time.
