I am referring to is a scrubber and the use of the pedestal is due to a design flaw, since the high pressure pump should cut out after lifting the mill and leaving the low pressure pump running. We have now controlled the excessive temperature rise by adjusting the alignment of the pedestal. This is at the feed end trunnion bearing.
on a SAG mill and ball mills The solution for the SAG Mill is an adaptive controller which controls mill load using direct mill weight measurement or indirectly from bearing oil pressure. The solution automatically controls ore master feed rate and water addition to increase throughput, while keeping mill load within
