Innovative Gear Drive Solution for Grinding Mills E MJ

Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.

Smooth Operators: Wichita multi-plate clutch technology

The clutch’s primary role on the dual-pinion, direct-drive geared mill is to provide smooth starts during mill startup. When the mill is running, the clutch also serves as a torque “circuit breaker,” reducing costly repairs and downtime by protecting the pinions and ring gear from potential damage caused by large pieces of grinding material.
