Outokumpu Technology’s TPLTM for elimination of material

Mar 14, 2007· 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.

Slurry flow in mills: grate-pulp lifter discharge systems

Ideally, the discharge rate through a grate-pulp lifter assembly should be equal to the discharge rate through at a given mill hold-up. However, the results obtained have shown that conventional pulp lifter designs cause considerable restrictions to flow resulting in reduced flow capacity.

Optimizing your SAG mill operation International Mining

The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates. Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills.
