An electrical impact study between variable speed dual ...

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].

What''s the Difference Between SAG Mill and Ball Mill ...

 · The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill''s ...
