Thickener
Conventional Circular Thickener is simple but can be very large. The conventional thickener has a central feed well for introducing the feed slurry. The top of the thickener acts as a clarifier and the clarified liquid overflows a peripheral at the top. A rake in the bottom consolidates the thickened solids and moves them towards a central ...

Beginners guide to thickeners
Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.

Thickener Selection Parameters
In the conventional thickener, particularly in the smaller units, the feed well is primarily a baffle to absorb energy. Usually it is a simple cylinder and can be roughly sized using a figure of 24 gpm/sq.ft. of area. This will approximate usual mill practice. This figure can vary between 15 and 70 gpm/sq.ft. according to the material being ...

The Conventional Thickener
The torque capability of a thickener drive is specified as Duty Rating being the maximum mechanism design strength or the setting on the Torque Control Box. The torque, in turn, depends on a K factor and the thickener diameter based on the following formula: Torque (in Nm) = 14.6*K*D 2 (in meters)

Paper: Dewatering to higher densities
Abstract: The development of high density and paste thickening technologies has changed the economics used in evaluating the benefits of increased thickener underflow density. This comes at a time of increasing competition for scarce water resources and a tightening regulatory framework in both water use and impoundment.

Forty years after the first high capacity thickener was developed, there are still arguments in the selection of conventional thickeners or high capacity thickeners in mineral processing. The arguments will continue unless there is a clear picture of capital cost vs. operational cost for each of the thickener types.
