Mill drive selection for semiautogenous grinding mills

the SAG mill with the dc drive. The ac synchronous motors used in the gear and gearless drives have a higher efficiency than the dc drive. Thus: for large motor horsepowers, the efficiency would affect the operating cost of the operation. Typically, the overall drive efficiency when using an ac synchro-nous motor is 92~0, whereas the equiva-

Increasing availability through advanced Gearless Drive

When using a motor without bearings, the whole drive system only has two (2) pulley bearings and no couplings versus conventional design which requires twelve (12) bearings and two (2) couplings (figure 3). A low-speed synchronous motor with bearings would need two addi-tional bearings and a large coupling between the motor and drive pulley.
