sag mill sag is an acronym for semi-autogenous grinding. sag mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. sag mill is generally used as a primary or first stage grinding solution. sag mills use a ball charge of to 21%. the largest sag mill is in diameter, powered by a MW may 15, 2014 sag mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. the largest sag mill is in diameter, powered by a MW motor autogenous grinding mill sag they are so-called due to the self-grinding of the ore. the operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed
slurry from the grinding circuit, at approximately 35% solids and 8085% passing 135 mm is pumped to three thickeners. thickener underflow, at approximately 54% ww solids, is pumped to a train of four acidulation tanks. sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. process air is also injected into the acidulation tanks to aid may 02, 2017 weir was retained by phil gold processing and refining corp to undertake refurbishment work of a semi-autogenous grinding mill to be used for gold processing. the work included welding. once completed, the sag mill was recommissioned and began operating in sag mill optimisation & increasing throughput at phu kham Dr rajiv chandramohan, robert braun, greg lane, kirsty hollis, johnson le, dirk baas paper presented by dr. rajiv chandramohan at ausimm mill operators conference, brisbane, august 2018.

oct 25, 2018 At the lihir gold mine, the concentrator plant was utilizing sag mills bearing pressure to calculate load measurement for their mill. following a series of sag mill overload events that caused significant milling downtime, the mill operators and metallurgists lost confidence in the repeatability and accuracy of the load measurements.dec 16, 2020 gold ore plant grinding media size several operations have experimented with progressively larger ball sizes in efforts to improve sag throughput, particularly with hard, coarse ores. while the energy of individual impacts increases with larger balls, the number of impacts for a given load decreases. dec 22, 2020 gold plant ball mill circuit operation. very often in sag circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent.
