autogenous and semiautogenous mills. other articles where semiautogenous mill is discussed mineral processing grinding development is the autogenous or semiautogenous mill 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, to percent grinding bodies usually for mining and wet grinding applications we produce ball mills, rod mills, and mills, and also plan complete crushing and grinding systems for our customers that we implement quickly from the first idea up to going into operation.
picking the proper crushing and grinding method must, therefore, be done with great care, so the best circuit is chosen. In the past years, there has been a strong trend toward using autogenous or semiautogenous grinding in mills throughout the world. autogenous grinding is favored when the ore is quite competent and a fine grind is needed.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.

AG autogenous mill. autogenous or autogenic 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
mar 17, 2016 question what is an autogenous mill? An autogenous mill is a grinding mill used in the minerals processing industry. It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force. gravity assistthe main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. materials are put in cylinder through the feed opening and then thoroughly grinded. the falling course of iron balls and ores can produce huge falling impact and autogenous grinding.
high-pressure grinding roll. sag and ball mill for gold ore grinding. one of three sag mills with 9.75 diameter and 4000 kW drive power. these mills operate in conjunction with ball mills for iron ore grinding the efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding. sometimes, in order to improve the processing capacity of the autogenous mill, a small number of steel balls can be appropriately added, usually accounting for of the
semi-autogenous grinding mill. wet or dry; higher capacity than a-g mill grinding; primary, coarse grinding grinding media is grinding feed plus ball charge high capacity less sensitive to feed composition semi-autogenous millball mill is the key equipment for grinding materials. those grinding mills are widely used in the mining process, and it has a wide range of usage in grinding mineral or material into fine powder, such as gold, ironzinc ore, copper, etc.. jxsc mining produce reliable effective ball mill for long life and minimum maintenance, incorporate many of the qualities which have made us being
