Single-pinion and dual-pinion fixed-speed gear drives offer a relatively simple design. However, process flexibility and optimization can only be achieved with variable speed drives. Furthermore, mechanical problems and maintenance for gearboxes increase operating cost and reduce availability of ball and SAG mills.
It is very common that the SAG mills are operated with adjustable frequency drives (AFDs) and the Ball mills are operated at fixed speed . . When mill power is between 18 and 20 MW, which is the current manufacturing limit of ring geared mills , either a gearless mill drive (GMD) or a ring geared mill with dual pinion.
