Slurry pooling and transport issues in SAG mills

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.

This paper uses a 1-way coupled DEM–SPH method in three dimensions to analyse the full slurry flow for a 1.8 m diameter by 0.6 m long AG/SAG pilot mill. This provides detailed information on the internal flow of slurry within a SAG mill, including the prediction of dry regions and of slurry pooling.

the SAG mill and ball mill was 8658 kW, which caused partial over-grinding. From experience in processing plants outside of China, the power rating of the ball mill should be higher than that of the SAG mill [5]. The pebble crusher had an over-powered configuration. The installed power draw of 630 kW
