design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.
Intelligent Gearing System Solution To
The mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear. The mill is also equipped with a barring drive which is either connected to the main drive reduction unit or alternatively mounted at the back of the main motor. Refer to Figure 2 for a schematic of the mill drive system.
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.
