SAG and AG Mill – Amstar Corporation

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Amstar SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Power-based modelling of single-stage AG and SAG mill

F80 is the milling circuit feed 80% passing size, µm, fSAG is a calibration parameter for pebble crushing and/or fine feed (typically 1.0 for 80% passing six inch mill feed and when no pebble crusher is present). WiBM is the Bond ball mill work index, unitless CFnet is an empirical adjustment to a ball mill circuit [CFnet = 2.35 - 0.29 × ln(P80)]

Modelling SAG milling power and specific energy ...

2015-1-1  The ball charge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric filling which depends on the ore size distribution (specially the % +6″ and the % −6″ +1″), on the rotational speed (N/Nc) and on the solid concentration by weight fraction inside ...
