Alumina Technology (CETI Enterprises)
In most of the existing Alumina refineries, ball mills are operative. Few plants in the World have rod mills and a few have two stage grinding system with combination of rod mill in first stage and ball mill in the second stage. It has been practically seen that ball mill generates more fines compared to rod mills.

a semi-autogenous (SAG) mill. AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process, where the second stage is carried out by the ball mill, but they can also be used as a one-stage grinder. The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills.
