BrainWave SAG mill - ANDRITZ

BrainWave is ideally suited to stabilize the operation of SAG mills. Effective grinding in a SAG mill depends largely on how it is loaded. A mill containing too much material does not allow for adequate movement of the ore and balls. A mill that does not contain enough material does not take advantage of the autogenous grinding mechanism.

Selecting Inching Drives for Mill and Kiln Applications

the required mill speed in conjunction with open gear set ratio, and main drive gear reducer ratio where applicable. The normal duty of an incher is intermittent. Therefore lower service factors can be specified since the expected 25 years life of the mill / kiln, the inching system would operate infrequently.

Autogenous and Semi-Autogenous Mills | FL

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.

Composite PulpMax™ mill liners can lower costs .

Safe and speedy replacement. Thinner mill liners result in a larger volume inside the mill. This means you can have a higher charge level. Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.

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.

Outokumpu Technology's TPLTM for elimination .

Outokumpu Technology's new design, TPLTM is a result of these material transport problems. As the internal design of the TPLTM approximates a grate, peripheral discharge or a grate, open-ended discharge, it keeps the slurry/pebbles away from the grate once they enter the pulp lifter chamber, thus completely eliminating flow-back and carry-over problems.
