The new practice of applying full pre-crushing of SAG mill feed to substantially increase throughput is challenged as retrogressive and inefficient at a time the industry desperately needs to ...
Feb 01, 1994· The Prediction of SAG Mill Product Size Distribution In a comminution circuit based on a SAG mill followed by a ball mill, the SAG mill product size is an important design parameter that needs to be established. This is necessary to fix the size of both the SAG mill, and the ball mill. Consider the following hypothetical example.
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' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
Mill Power Draw Model Bibliography. Mill power draw models are used to predict the usable power draw that a particular mill will generate. The three SAG mill models are benchmarked and reviewed in: Doll, A.G., A comparison of SAG mill power models, Procemin 2013; Austin SAG Model. The Austin SAG model was published in: Austin, L.G.

The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill .
The −20 + 10 mm fraction pebbles are compared with steel balls as media for grinding of a copper concentrate in a vertical stirred mill, which obtained from a 7.0 m diameter × 3.5 m SAG mill at Jiangxi Copper Corporation, China.
AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.
