The standard method for sizing secondary ball mills (usually the overflow type) in AG/SAG circuits follows published mill supplier information with aspect ratios in the range 11.5 to 12.0, depending upon product sizing and pulp flow, i.e., the highest expected circulating loads (Morrell, 2001). The applied net power, calculated from testwork
Oct 01, 1999 Consequently, the effect of larger mill sizes is to both increase operating stresses generally and to reduce the design stress criteria. For this reason, the stresses in the completed mill are generally closer to the nominated criteria at more locations in the mill than was the case in the older, smaller mills.

SAG is an acronym for semi autogenous 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 12
Nov 26, 2019 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 ...

Jun 06, 2016 Semi-Autogenous Grinding (SAG) Mills. The shell liner profile possible is primarily determined by the chordal dimension. The profile must minimize packing and plate wear but give sufficient lift for proper grinding action. Liner profiles are as numerous as operations. They range from typical plate and lifters to rail or integral liners.
Jun 06, 2016 Traditionally, many engineers approached SAG circuit design as a division of the total power between the SAG circuit and ball-mill circuit, often at an arbitrary power split. If done without due consideration to ore characteristics, benchmarks against comparable operating circuits, and other aspects of detailed design (including steady-state tests, simulation, and

Apr 17, 2018 Obviously, the SAG mill is consuming more and the ball mill less power than was predicted by the empirical method, but the overall total is 99.5% of the predicted total. Examples The Hemlo gold project of Teck-Corona (1000 mtpd) provides an example of mill sizing using the empirical calculation method alone.
