SAG Mill Components - Mineral Processing & Metallurgy There are a number of mills in the cement industry in Europe, which have operated for more than three years with this type of drive. Reversible rotation is often used to obtain balanced wear on mill liners and lifters, to reduce the number of mill shutdowns. This feature can easily be incorporated into dual pinion or gearless drives.
