WesTech's HiDensity™ Paste Thickener produces non-settling thickened tailings with lower viscosities and underflow concentrations than what is produced in the Deep Bed™ Paste Thickener. The HiDensity Thickener also has a lower height-to-diameter ratio, which allows for on-the-ground construction and much larger diameters.
EvenFlo® Feedwell
The thickener or clarifier is the major piece of equipment used to recover water in mineral and industrial processes. The one thing all thickeners have in common, the feedwell, is the core of every thickener's performance. A thickener relies on a feedwell for even distribution of solids and flocculation of suspended particles.
Design Considerations for a Tailings Disposal System | E
A deep cone, or deep bed, thickener produces paste. Both high density and deep cone thickeners depend on retention time rather than area. Yield stress is the dividing line between paste and thickened tailings, and deep cone thickeners produce a yield stress of 120 to 150 Pascals (Pa) and greater.
Design of a WesTech HiDensity Paste Thickener for …
WesTech DeepBedTM paste thickeners (sometimes referred to generically as deep cone type thickeners) are characterised by a height to diameter ratio between one and two, a bottom cone angle of 15-45o, and a bridge mounted drive. Diameters are limited to about 24 m for this type of paste thickener. The mud bed height is

Paste Thickeners
A compromise option of using a rakeless (ULT) design can be considered. In this case, the cost and complexity of a mechanical drive is traded off for a deep mud bed and steeper 60 degree floor slope picture. The ULT design will not achieve the same underflow density as the paste thickener with rake and pickets, but it can be more economical.
Replacing Filters with Paste Thickeners
paste thickener was significantly lower than the high usage of belt press filters. PasteThick™/WesTech recommended and provided a system layout to place the paste thickener near the impoundment site to reduce the cost of transporting the paste thickener underflow.
