Factors Influence Ore Grinding Mill Efficiency

The medium filling rate is the volume ratio of the medium and grinding cavity moves in throwing and falling state in a ball mill. The throwing motion medium is used to smash large ore and the medium of falling movement mainly plays the role of grinding. The filling rate of the fine grinding mill is about 5% lower than that of the coarse grinding.
