Mill drives: the desire for increased power and the,
SAG mill drives (as GMDs) by some operators and principal motor designers/manufacturers until the reasons for known problems in design or manufacturing were better understood and resolved. Accordingly, the latest 40 ft dia. SAG mill is rated at 29 MW and 78% C.S., with a 42 ft dia. mill built but not yet operational. The more recent option of operating at higher ball charge volumesSelecting Inching Drives for Mill and Kiln Applications,Mill drive inchers can use this low value of service factor based on the limited operation over the twenty five year expected life. Regular inspections of the gear drive, control of moisture and dust ingress, and regular lubricant sampling and changes are required to have the expected life match the actual life of the drive system.
