Thickening Resource Book

A thickener has several basic components a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal system, and an overflow launder.

Thickener Operation Zeroday Enterprises

Jan 26, 20150183;32;c) Under flow pump which can be of several types including peristaltic, centrifugal, diaphragm and progressive cavity. Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener.

Conventional Thickeners Solid Liquid Separation

For bridge and column type thickeners with tanks that are mounted on ground level the access to the slurry pumps is trough a tunnel. For very large column type thickeners the column is constructed as a caisson that is submerged in the slurry so that the pumps are housed at the bottom of the chamber and deliver the underflow upwards.

Thickener Underflow Atlantic Pumps

Currently the most common pump to be used to remove the thickener underflow, a centrifugal pump is not necessarily the best option. From a spares perspective they are the most cost effective pump however using a centrifugal pump carries a number of issues. Firstly, the slurry has to be watered down to go through the pump, which is somewhat
