HD Technologies Case Study

SAG mill designs now include a single pinion drive that is used to transmit 5.6 MPa (7500 hp) to a mill. Consequently, it is now possible, with a twin pinion drive, to have power transmission delivering I 1.8 MPa (15,000 hp) to a mill. This power level is now approaching that available through the gearless drive system. Consequently, the ...
