Macpherson Autogenous Grindability Test Mining Sgs
the mill power draw, throughput and product size distribution are used to compute a specific energy input and the macpherson autogenous work index although the importance to achieve steady-state in a grinding test is widely accepted the macpherson test remains the only small-scale agsag mill test that offers this option.sep 01, 1989 It is evident that mechanisms of grinding must be different or at least have different importance from both ball mills and from large diame- ter autogenous mills. therefore some of the assumptions made for ball mill models are not appropriate and ball mill models cannot be used in mod- elling autogenous mills nor pebble mills.compared with sag mill grinding, autogenous grinding using feed prepared to include coarse, competent rock and crushed finer rock resulted in a 14% reduction in grinding energy expressed as kwht and no steel balls were required as additional grinding media. the coarse rock amounted to about 20% of the mill feed.autogenous mill is a kind of media free grinding equipment, which relies on the mutual impact, grinding and grinding of materials. It has the advantages of no medium, large feed size range no primary crushing of run of mine, convenient use, high output, even discharge, etc. it has been widely used in ore processing industry.
Autogenous Dry Grinding Mill
the importance of grinding autogenous mill youtube jul 2012 hardness of the grinding medium in the mill is not possible. two commonly used grinding mills are the.dry grinding rod mills grinding circuit rely on our proven track record of sag and AG mill superiority. since the early we have been designing and manufacturing semi-autogenous and autogenous grinding mills under the fuller-traylor brand. semi-autogenous grinding uses a minimal ball charge in the range of while autogenous grinding uses ore only.many mills utilize a grinding wheel which breaks material into smaller parts as it moves against the workpiece, which can also move ground material from the grinding surfaces to a collection area. some major types of mills used for industrial grinding include ball mills, vibratory mills, and rod mills.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.
