Dual Drive Ball Mill

Oct 22, 2015 An electrical impact study between variable speed dual pinion mills and gearless mill drives Abstract: Conventional mining process circuits use both Semi-Autogenous Grinding (SAG) and Ball 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 [1].
