Deep Bed™ Paste Thickeners - WesTech Engineering, Inc.
The original concept of the deep cone thickener was developed in the 1960's using a steep angled cone and thickener bed to increase underflow density. Over the years, this thickening technology has evolved to produce a non-settling solids suspension with underflow concentrations much higher than what is produced with conventional or high rate ...

Influent suspended solids (the raw ...
A Theoretical Model for the Rake Blockage Mitigation in ...
To produce high concentration underflow, the yield stress of underflow in DCT is much higher than conventional high-rate thickeners, resulting in a much higher rake torque demanding for DCT . The yield stress of the suspension, rotation speed, and rake structure have great influence on rake torque [ 26 ].
The High Rate Thickener - Solid Liquid Separation
Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow ...

EIMCO-K.C.P. High rate thickeners are designed to provide high underflow concentration with smaller diameter. The high velocity feed is split to two compartments with opposite tangential inlets that are positioned in two levels, an upper and a lower one. Between those compartments there is a narrow gap through which the flocculent solution is ...

Beginners Guide to Thickeners - Outotec
In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.

Paste Thickeners | McLanahan
Paste Thickeners can help producers eliminate the need for settling ponds and other structures. They are meant to achieve the highest solids concentrations possible through gravity separation. The resulting mud, described as a paste, is often so thick that it becomes non-segregating — no further separation of water and solids can be achieved. As a guide, a paste material is measured with a ...

Thickener Torque -Rakes & Drive
A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener ...
