sag mill dual pinion geared drive

Paper # 25 Copper Mountain Overview on the Grinding

DUAL PINION MILL DRIVES The SAG and the two ball mills are gear driven and Copper Mountain selected the sophisticated low speed dual pinion mill drives from ABB to drive these mills. Brief History Sophisticated Dual Pinion Mill Drive Technologies About five years ago, ABB was already the market leader for Gearless Mill Drives (GMD). ABB

OPERATING STRATEGIES Innovative Gear Drive Solution for

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.

SAG Mill Components Mineral Processing & Metallurgy

Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly
