sag mill semi autogenous grinding mill in mineral
Semi autogenous Outotec SAG mills as they are often called can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages. Get Price

Mineral Processing
AG/SAG mills accept a coarser feed than do rod/ball mills. Typical AG/SAG feed particle sizes range up to 30 cm 12 inches which corresponds with the product size of primary crushing. They do require primary crushing so that the randomly sized run of mine ore is reduced to a uniformly distributed feed size acceptable to the AG/SAG mill.
