SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21 . The largest SAG mill is 42' in diameter, powered by a 28 MW 38,000 HP motor. processing copper ore in sag mills
A feature of ball mills is their high specific energy consumption a mill filled with balls, working idle, consumes approximately as much energy as at full scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
Ball Mill High Capacity. We are a large scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel, concrete, etc
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol. ore and 25 steel. The ball mill is operated in
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
and ball mills, have almoste obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous AG or semiautogenous SAG mills,bined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life. Every second counts, and adjusting these parameters within

25/08/2014· There does seem to be a trend of SAG mills being changed into high aspect ball mills, we have encountered a few in recent times. This has brought about a new ball design to reduce spawling as the higher ball charges are causing increased ball on ball incident. So perhaps we should not evaluate SAG mills in the traditional configuration of perhaps a +/ 12 ball charge and a <20 total charge in
