The alumina thickener upgrade is a multi-year, multi-unit retrofit project. In the first project phase a new Ø22m elevated deep cone thickener was designed, fabricated, erected and commissioned.
Fines Recovery and Water Management Equipment by McLanahan ...
Fed from the top, deep cone thickeners originally rely on the process of free-settling. After the fines reach a certain point in the process they continue to thicken through hindered settling. Depending on the characteristics of the material a deep cone thickener can be designed with no moving parts, or with pickets (rakes) that rotate slowly ...

Paste Thickeners 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 ...
Gravity Sludge Thickening Tanks for slurry dewatering | LZZG
High-efficiency sludge thickener instruction. The deep cone sludge thickener tank is based on the traditional vertical flow sedimentation tank. The structure of the internal feed cylinder is improved, the efficiency of sedimentation is greatly improved, the plane of the sludge thickening tank body is circular, and the suspended solids settle under gravity.

Treatment of coal tailings
· This technique used deep cone thickeners (DCT) of approximately 4 m diameter with a 60° cone angle (Fig. 16.21). The small diameter units were installed in multiple groups to obtain the throughput required for each particular plant. The feed to the thickeners was heavily dosed with flocculant, and an extremely thick underflow density was achieved.
