In general, the sag mill manufacturers will control the addition amount of medium such as steel ball at 28, so that the capacity of semi sag mill to process materials can be increased by 1030. the sag mill liners wear will increase by 15 due to the impact of medium such as steel ball during the sag mill.
Attrition mill is a type of grinding mill by kinds of media to crush lump to powderlike substances. the impact can be rock on rock such as in an autogenous grinding (ag) mill, rock and a small ball charge (10), used in semi autogenous grinding (sag) mills, balls of various sizes in ball mills and less commonly these days, steel rods in rod mills.
Sag mills generate higher levels of impact reduction and ball mills higher levels of abrading action. a mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.
Sag mill vs ball mill. ball motion inside a sag mill. ball motion inside a ball mill. to a more significant degree than in other comminution devices, liner design and configuration can have a substantial effect on mill performance. in general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity.
Sag is an acronym for semiautogenous grinding sag mills are autogenous mills that additionally use grinding balls like a ball mill a sag mill is normally a major or first stage grinder sag mills use a ball charge of eight to 21 the biggest sag mill is forty two 128m in dia,difference between sag mill and ball mill.
Ball mill when the particle size of the product is less than 0.5mm the grinding effect of the ball mill is greater than that of a rod mill of the same specification sag mill the sag mill has a wide range of feeding particle sizes and can process larger minerals but at the same time its output particle size is relatively larger.
Mills (sag,ag, rod, ball, pebble) – bateman engineered . sag and some ball mill applications. this is a screen grate installed near to the discharge end of the mill which has slots to allow the material to pass through. it.
Mills in the older plants that had many mills in parallel. in fact this is generally still the case in the multistream plants, where mill liner design and selection is only tackled on a cost consumables basis. however, the gains to be had through good liner design and selection are just as great as on the large sag mills.

Multotec has supplied a number of trommel screens for 38 to 40 sag mills that required 500 to 600 mmhigh weir bars to create sufficient retention time. whereas the scrolls on ball mills are cast onto the screen panel, the arduous duty associated with sag mills requires scrolls to be bolted directly to the steel support frame. multotec.
The biggest characteristic of the sag mill is that the crushing ratio is large. the particle size of the materials to be ground is 300 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. the calculation shows that the crushing ratio can reach 3000 4000, while the ball mills.
Difference Between Sag Mill Vs Ball Mill Mech4study
1. sag mill is the primary tool for grinding. sag mill is used before the other mills. ball mill is a secondary, and it is used after the sag mill. 2. sag mill breaks the raw material into pieces for the further grinding. ball mill is used to grind the pieces of raw material into. powderlike structures. 3.
Of large agsag mills and large ball mills. however, it is necessary to discuss their operation because a rod mill product has a similar slope to agsag mills. this product slope averages less than 0.5 when plotted on loglog paper and therefore contains an extra amount of ne material ﬁ compared to a psd, having a 0.5 slope. this ﬁ ne material,.
