In this type of application sometimes even larger the pinion is mounted on pillow blocks driven by a low-speed motor or a motor and en-closed gear drive. The gear is mounted on the mill using a flange bolted con-nection (see Figure 2 for one type of flange installation). Both the center distance and alignment are adjustableWe are essentially providing up to twice the power transmission of a conventional dual pinion drive. Gearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing Outotec to produce the world's largest SAG mill of 42' in diameter drawing power at 28 MW. Today,

either a gearless mill drive (GMD) or a ring geared mill with dual pinion motors can be chosen. Selecting between gearless or ring geared design is mostly dependent on size of the mill and power and speed requirements [3].The clutch's primary role on the dual-pinion which is the current manufacturing limit of ring geared mills [2],

with both larger and finer feed sizes ...The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm and the pebbles have the option to be fed to Plant I (open circuit) or back to the SAG (closed circuit). Oversize rejects from the SAG mill are transferred to the SAG mill feed conveyor by three ...ABB ring-geared mill drive solutions correspond to the latest technology and are designed for reliable,
