Optimizing your SAG mill operation
Mar 21, 2007 · The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...
Efficiency of the Detritor Mills at Zinifex Century Mine
The Zinifex Century Mine employs a large number of Detritor mills for fine and ultrafine grinding to liberate silica and sphalerite at 80 per cent passing microns before final zinc flotation. A joint project between CSIRO Minerals and the Zinifex Century Mine was carried out to evaluate the Detritor mill performance. Plant surveys were conducted around the Detritors in conjunction with ...
