Pinion On Sag Mill

SAG Mill Components - Mineral Processing & Metallurgy

If the mill requires approximately 6000 horsepower or less, it is possible to drive it with a single pinion. To date, however, economics has dictated that most mills over 3500 horsepower be driven with two pinions, using wound rotor motors driving thru speed reducers.

Mill Pinion Gears | David Brown Santasalo

Mill Pinion Gears Our high torque, high precision integral and non-integral mill pinions are used in SAG, horizontal ball mill and rotary kiln applications across the globe. Supplied as an individual component or as a fully optimised system comprising a girth gear, mill drive gearbox, pinion and barring drive, our pinions are manufactured double ended for reversible and extended operating life.
