Factors Influence Ore Grinding Mill Efficiency JXSC Mining

2019. 5. 10.  When the concentration/ thickness is too low, the slurry flows quickly and the adhesion degree on the medium is low, which weakens the impact and grinding force grinding mill apply on the ore material. Contrarily, high concentration, high adhesion may slow the flow speed, cause over grinding thus influence the production capacity.
