economic benefits of semi autogenous mills

ABB acquires ring motor business from Alstom

Raw material from the crushing stage is typically fed to SAG (semi-autogenous), AG (autogenous) and ball mills for further processing to break the rock into smaller pieces. These mills are large rotating cylinders, from 10 to 15 meters in diameter. They can grind hundreds of tons of ore per hour. Get price

Comments on the Exemption of Certain High Chrome Cast

There are three types of mills commonly used for ore mine, i.e. autogenous mill, semi- autogenous Grinding (SGA) mill and ball mill. Autogenous mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer Get price
