Paper # 25 - Copper Mountain Overview on the Grinding ...

The grinding process with one 34' x 20' SAG mill and two 24' x 39.5' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new state-of-the art dual pinion mill drives.

SAG Mill Components - Mineral Processing Metallurgy

18/04/2018  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 balanced load division to the gearing. Until more experience is gained on this type of drive, Allis-Chalmers and major gear drive
