What is a thickener? A thickener is generally used in slurry applications and in waste water management where large scale separation of unwanted fine-grained solids and liquids is required. The thickener from Propel Industries produces high density underflow slurry and clear overflow water. Up to 85 to 90% water is recovered from the feed. The

Increasing underflow density results in a material with a higher yield stress being raked increasing the rake torque and limiting the achievable underflow density. In a similar way the depth of the bed is also limited by the thickener geometry. Philosophy. Typically, thickener controls are implemented as single loop controllers in DCS/PLC systems.

It should be remembered that both the thickener rakes and the underflow pumps (or valves) transport the thickened underflow. The size of the solids inventory determines the bed depth and the residence time that solids will experience in the thickener. This, in turn, determines the underflow slurry rehology and the water recovery to overflow. ...

This document presents a mathematical model for predicting rake torque in paste thickeners. The model shows that rake torque increases with underflow concentration and is modeled as a polynomial function of concentration. Bed height has a slight effect on rake torque, causing around a 0.27% variation. The model was confirmed using operational data from a lead-zinc …
