Oct 12, 2017 ball mill is a fine grinder. a horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. the ball charge of a sag mill is about 29 to 30. by friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.Specialist in balls for sag mills in fsb we produce our high quality steel grinding balls using top quality steel , purchased in some of the best steel mills in europe . in forjas santa barbara we produce grinding balls by closed matrix drop forging process, which allows us to give the balls the characteristics that allow them to achieve the ball mill.
Semi-autogenous metso outotec 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.
Sag mill grinding mediakemcore sag steel forged balls are manufactured grinding balls in nominal sizes from 90 mm to 140mm. with average wear rates of 0.6kg/ton, theyre among the best ball mill.Autogenous semiautogenous grinding circuits. semiautogenous plus ball mill has been the work horse of mills sag vs ball mill advantages ag sag mill grinding compared – which is best grinding rods and balls can be obtained in uniform sizes weights and of a specified quality their action in a mill can be reasonably predicted.
Apr 25, 2013 ag or sag mill, intermediate grinding to a ball mill or tower mill, and ﬁne grinding to a stirred mill such as an isamill or stirred media detritor smd. of course, various exceptions to these typical values can be found. in ﬁne grinding, a material with an f80 of less than 100 lm is comminuted to a p80 of 7 to 30 lm. p80s of.
Jun 01, 2005 anyway, sag mills can be calculated as inefficient, except they do not require a large grinding load like ball and rod mills. capital and operating costs have to be compared, system vs. system in order to assist with the selection. the feed suitability vis-a-vis the grind method is critical.
With high aspect ratio sag mills total charge to ball charge ratio should be greater than 2 up to 2.5 for a coarse mill feed say f80 110 mm. if the mill feed size is fine, say 50 mm or 30 mm, then you are looking at a total charge to ball charge ratio of about 1.5-1.6.Jan 27, 2020 these two types of mills are filled with varying compositions of grinding media. sag mills contain balls of up to 150mm in diameter that occupy 5-18 of mill chamber volume. ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25 - 40 of mill chamber volume.
Which just has started commercial operation earlier this year. the grinding process with one 34 x 20 sag mill and two 24 x 39.5 ball mills will be briefly discussed. all three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. copper mountain has installed on all three millsball mill.Aug 19, 2019 hpgr wear vs conventional mills. ball, sag and rod mills all require their grinding media to be regularly replaced, unlike a hpgr. high pressure grinding rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.
