The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
convert the Katinniq Concentrator Mill to SAG had in fact commenced as early as 1999, but were halted owing to alternative process improvements which achieved up to 1Mtpa as early as 2000. Up until this time, plant process controls had remained more or less static; modifications having been limited to those required by new equipment.

GCA has successfully commissioned two KC-QS48/ICS FL Knelson Concentrators at Asanko Gold's project in Ghana.. The KC-QS48s at Asanko are each rated at 400 tph solids (40-70% solids in feed pulp). The plant design was a fairly 'standard' and well-proven design, which incorporated a coarse crusher, SAG mill, and a Knelson concentrator.
The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the

This was a great experience encompassing the operation as well as a walk-through of Prominent Hill's SAG mill relining via 360 o photos, something we wouldn't have experienced had the tour been in person. From this, we visited Ausenco's Brisbane office to walk through the Carrapateena 3D model Ausenco designed.

The SAG mill design is based on Outotec's proprietary grinding mill technology, developed over decades for maximum reliability and performance. The mill will be operated as a single stage SAG mill (primary and secondary duty combined) with very high throughput made possible by the use of Outotec's patented Turbo Pulp Lifter (TPL(TM)) Technology.
February 6, 2008 Vancouver, BC - Taseko Mines Limited (TSX: TKO; AMEX: TGB)("Taseko") is pleased to provide an update on the concentrator expansion at its owned Gibraltar Mine in south central British Columbia.. The Semi-Autogeneous Grinding Mill ("SAG mill") and its Ancillary operating components were released from the construction group to Gibraltar's mill …
The three gearless mill drive (GMD) systems are the ABB most powerful ever made. The GMD for the 40-foot SAG mill has a power rating of 28 megawatts (MW), and the GMDs for the two 28-foot ball mills have a power rating of 22 MW. They are the largest diameter and most powerful SAG and ball mills drive systems at the highest altitude installed to ...
at Frank concentrator, which is being used to study the influence of a variety of grinding parameters. This paper will discuss only the influence of mill speed and pulp density on secondary stage grinding. A ∅0.82 x 1 m open circuit mill was used with reclaimed Merensky tailings as feed.
The concentrator looks like having a SAG and ball mill configuration without a pebble mill (at least in the initial stages), plus a large cell bulk flotation circuit with columns for cleaning. It would have a separate float for tailings separation and produce both a copper and molybdenum concentrate.
