A Short History of Deep Cone Thickener Development
mud applications, more typical numbers are 25-30 wt% for conventional thickeners versus 40-45 wt% for a deep cone thickener that is a third of the diameter. Bagatto (1989) had compared raked thickeners with rakeless ones and had also determined that the underflow could be controlled using the torque signal.
Deep Bed Paste Thickeners
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 …
