Also autogenous mills have grate discharges so as to retain the coarse grinding media in the mill while dispatching the fine particles. The other benefits of using autogenous grinding include – reduction of metal wear and elimination of secondary and tertiary crushing steps. Therefore autogenous grinding offers more savings in capital and
An autogenous mill of ID 6.7 m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20% of its volume. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed. The solids in the mill charge were at 80% solids. Estimate:1.
The Solios Carbone contract consists of the engineering and supply of all equipment for the following: hot crushing of the crust shovels and anodes butts cleaning bath; cooling in a metallic pan conveyor; processing in an airswept autogenous mill designed by Fives Solios for storage of the product dedi ed to the cover of the electrolysis pots.
Autogenous mills or AG mills 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 AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
The most important feature of autogenous mill is to feed the material from quarry or the primary crushed ore into the grinder. Normally the materials are fed into the rod mill according to the granularity ratio. The autogenous mill can grind the material to -0.0744mm. with the content of 20%-50% of the total output.
Find out information about autogenous tumbling mill. A type of ball-mill grinder utilizing as the grinding medium the coarse feed material. Also known as autogenous mill.
Other articles where Autogenous mill is discussed: mineral processing: Grinding: Autogenous mills operate without grinding bodies; instead the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills which have become widespread 5 to 10 percent grinding bodies usually metal spheres are added.
