If the advantages of a synchronous motor are desired on any dual pinion drive application, dual synchronous motors are available to drive dual pinion gear arrangements featuring load sharing control devices. These continuously monitor individual mill power and adjust each motor with respect to the.other, such as the D.C. field, to achieve a
Some consultants have the view that the gear drive is limited in power. Mr Craig Denecki (Falk Milwaukee) in his paper, presented at the 1996 SAG mill conference, provided details of the then largest gear drive in operation on a SAG mill (34ft x 18ft) at Escondida 13.4MW, which began operation in 1995. The reason for not having larger gear drives
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

When mill power is between 18 and 20 MW, which is the current manufacturing limit of ring geared mills [2], 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]. This paper
