Semi-autogenous mills or 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
Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. Metso offers flexible autogenous (AG) mills, semi-autogenous (SAG) mills, ball and pebble mills, as well as stirred mills to fit your needs. Grinding mills, spare and wear parts as well as maintenance and optimization services.
Semiautogenous mill note the size of the mill why does the diameter need to be so big ball mill or pebble mill agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill amit 135 lesson 6 grinding circuit.
We buy, sell and consign SAG Mills of leading manufacturers like Metso (Allis Chalmers, Dominion, Hardinge, Allis Minerals/Svedala), FLSmidth and many more. SAG is an acronym for Semi-Autogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to …
Autogenous & SemiAutogenous Grinding Circuits. Autogenous Grinding Circuits When an ore is hard and competent, there is always the possibility that it would make good "pebbles" which could be used for fine grinding media Different methods that have been tried using combinations of autogenous, semi-autogenous, pebble and or ball mills The flowsheets shown are typical of the properties
A variable speed drive on large primary semi-autogenous mills can overcome this problem to a considerable degree. A major disadvantage of large semiautogenous mills has been the necessity to keep the mills fully loaded at all times to minimize ball and liner breakage.

Ball millsof greater length are termed “tubemills,” and when hard pebbles rather than steel balls are used for the grinding media, themillsare known as “pebblemills.’’ In general,ball millscan be operated either wet or dry and are capable of producing products on the order of 100 um.
Millsof MMPS type are generally used at the first grinding stage of the two-stage mode. Use of largemillsallows preliminary crushing stage exclusion.Ball millsof MSh type are designed for grinding of ferrous and non-ferrous metal ores as well as gold-containing ores.

The designs of autogenous andsemi-autogenous(SAG) grindingsmillsare described followed by the description of their methods of operation in grinding circuits involving crushersand ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.
