SAG Mill Operation at Cortez Evolution of Liner Design The maximum grinding circuit throughput as dictated by downstream conditions is about 13 500 dry tons per day 560 dtph Early in the Mill 2 life the ore had been predominantly ball mill limiting in that the ore basically blew through the SAG mill due to its already small size Regardless of this budget throughput....

Austin SAG model

History The SAG mill model by proposed by Leonard Austin 1990 was largely based on modifications of earlier tumbling mill models by Hogg Fuerstenau and F Bond The model uses a kinetic-potential energy balance to describe the power draw of a mill charge Many geometric components of the earlier models were fit to empirical relationships measured by Austin...

Freeing up milling capacity in a SAG mill ball mill ,

The harder component of the SAG mill feed from the primary crusher, that component with a higher bond work index, will be over represented in the pebble circuit relative to the mill feed In many cases the low grade or barren gangue component of the feed will have these characteristics of higher hardness and lower breakability relative to the mineralised component of the feed...

SAG Mill Process Control

If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load and power to hold a constant tonnage to satisfy another constraint elsewhere Underground mines are an example the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to what the shaft can supply...

A structured approach to the evaluation of the energy ,

The major benefits supporting this trend are better energy efficiency, improved grinding capacity, and higher metal recovery in downstream processes such as heap leaching and flotation In general there is limited quantitative knowledge on the true benefits of HPGRs relative to SAG mills in comminution, and about which situations one deals with better than the other...
