## Ball Mill Trunnion Bearing Lube System

On a 11’6” x 22’0” Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during startup of the mill System monitors including pressure switches and flow monitors are provided, along with temperature sensors that monitorModelling SAG milling power and speciﬁc energy consumption including the feed percentage of intermediate size particles In these circuits the SAG mill is the largest energy consumer In many engineering rectly measured with bearing pressure measurements, it was decided to discard it as an input variable The main reason is thatModelling SAG milling power and specific energySAG mill vs Ball mill Crushing ratio The biggest characteristic of the sag mill is that the crushing ratio is large The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 01 mmWhat's the Difference Between SAG Mill and Ball Mill
