To further clarify the dewatering performance and torque evolution during the tailings thickening process, a self-made rake was connected to a rheometer to monitor the shear stress and torque. The dewatering performance of the total tailings was greatly improved to a solid mass fraction of 75.33% in 240 min. The dewatering process could be divided into three …
Advanced thickener control
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.

Beginners guide to thickeners
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. ...

Why Full Automatic Rake Lifting Is Important for High Rate Thickeners
Traditional thickeners rely on manual or semi-automatic rake-lifting systems, where operators adjust the rake position based on visual observations or pre-set schedules. However, these methods can be inefficient, leading to suboptimal performance, increased energy consumption, and potential damage to the equipment.
