The new database includes 49 published SAG/AG mill surveys and includes mills from all over the world. The paper will compare the survey database to SAG mill models by Austin, Morrell and Hogg & Fuerstenau with the purpose of demonstrating the degree of fit of the models to surveys and validating any empirical fitting factors used in the models.

Austin proposed a geometric factor be applied to the formula for use in cone-ended mills. The author's experience from fitting this model to published surveys suggests that Austin's factor adds too much power, and proposes that 5% extra power should be added instead (based on Barratt, Brodie & Pfeifer, 1999).
AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the …
SAG Mill power draw models are used in mill design and grinding circuit modelling to predict how much power will be consumed by a particular mill geometry and operating configuration. This paper will compare SAG mill models by Morrell, Loveday (using "Power Numbers" published by Barratt) and Austin against several published mill surveys.
Experimental Study of Ore Characterisation Methods for AG/SAG Mills Mining companies have long recognised the importance of ore breakage characterisation in design and optimisation of their crushing and grinding circuits. In one of the industry standard methods relevant to AG/SAG milling, ore is characterised using mainly high energy single impact …
Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The …
The U.S. mining industry operates approximately 80 semi-autogenous grinding mills (SAG) throughout the United States. Both mine and mill site variables determine SAG mill …

EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies below 75 …
AG and SAG mills are very efficient at making angular particles round. Crushers are very efficient at making round particles angular. So there is a potential synergy from passing hard, rounded pebbles from a AG or SAG mill to a dedicated pebble crusher. The crusher product returns to the AG/SAG mill for further grinding.
