How a tailings thickener works

A thickener receives slurry, promotes separation between solids and water, removes clarified water through the overflow and discharges a more concentrated slurry through the underflow. Its response depends on how…

What causes torque to rise in a thickener?

Torque rises when the rakes encounter more resistance while moving material. Bed level can contribute, but it is not the only cause. Solids concentration and compaction, rheological behaviour, feed settleability,…
