sag mills diameter

Semi-autogenous grinding (SAG) mill liner design and

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

Autogenous and Semi-Autogenous Mills FLSmidth

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. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont’s Yanacocha mine in Peru is a single stage mill (no ball mill after the SAG mill) and has a diameter and length of 32’, driven by a 16.5 MW GMD from ABB. Above the Arctic Circle in Sweden, Boliden has just installed two 38’ diameter mills with

SAG Milling in Australia -Revised Submission

With such a support structure, it is no longer necessary to increase diameter to obtain a larger mill, and there is nothing to prevent a 1:1 aspect ratio mill of, say 10 m dia. x 10 m EGL equipped with a 20 MW motor from being fabricated. Such a mill would have a less arduous environment than, say, a 13.4 m (44-ft) diameter mill.

SAGMILLING.COM .:. Mill Critical Speed Determination

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute.
