Thickener with central transmission
Central transmission thickener is applied to mechanical discharging of small radial flow live vertical flow sedimentation sink and concentrated sink. It can further separate the free water in the sludge to reduce sludge and improve the concentration of sludge. Then, it discharges the concentrated sludge out of the sink. The structure, construction condition …

Maximize Precious Metals Recovery with CCD Circuits and …
From a process perspective alone, high-density and deep cone thickeners have a clear advantage over high-rate thickeners. Because of the wide variance in metal values between processes (e.g. copper leach versus gold/silver), we did not attempt financial assessment of recoveries with different thickener options.
