Guarantee the sharp and efficient separation of fine particles by density.

This operates on the fluidised bed principle.

The even distribution of upstream water through a nozzle plate produces a homogeneous fluidised bed. In this fluidised bed, lighter particles are separated and directed to the overflow.

Heavier particles are removed by discharge control to the underflow.

TAS type upstream sorters are in use in:

• Sand decoaling and
• Ore processing

with great success.
