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 thickeners. WesTech’s Deep Bed™ Paste Thickener is the latest advancement in the evolution of this style of thickener.
The WesTech Deep Bed Paste Thickener can thicken a tailings stream to non-settling paste at solids concentrations approaching that of a filter cake. Design characteristics of the Deep Bed™ result in maximum water recovery, maximum underflow density, and paste with minimal slump.
An extra heavy-duty high torque drive powers the raking mechanism without the need of a rake lift. Process controls allow the thickener to achieve the desired underflow density and overflow clarity with the minimum flocculant dosage.
