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.

Comprehensive Guide to Mining Thickeners
These thickeners feature a steep-sided cone-shaped tank, which promotes enhanced settling of solids. The deep cone design allows for a larger settling area and provides improved retention time for effective solids-liquid separation. Deep cone thickeners are commonly used in processes where particle settling rates vary or where solids ...
Wash Recycling
The flocculent dramatically speeds this process up and allows the clean water to over the top of the thickener into a collection tank, where it is recycled back into the wash plant. The sludge that has been collected at the bottom of the deep cone thickener is pumped into a buffer tank, where it is stored until enough volume is gathered.
