Factors Influence Ore Grinding Mill Efficiency - JXSC

2019-5-10  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. The motion state of the medium in the mill is related to the medium filling rate.
