Thickener control
WebThe control parameters used to maintain stable operation in high-rate thickeners are underflow solids density, underflow withdrawal rate, flocculant dosage, solids inventory in the tank, solids feed rate, and mechanical torque limit restriction of the rotating rake arm mechanism. Lower-yield stress muds, as produced in a high-rate thickener ... Web8 Aug 2024 · The thickeners can be classified into two types depending on location of rake driving mechanism. They are known as either Centrally driven or Peripherally driven.

Web19 Dec 2024 · The adjustable variables that control a thickener have complex interactions that are often poorly understood, and there are long lags between actions or disruptions. This can often result in conservative operation. Water quality is often neglected when defining thickener plant performance. High water recoveries result in increased recycling … Web7 Apr 2024 · Through accurate measurement of flocculent mass flow in thickeners, precise dosing pump control is realised. From the measurement, concentrations of overflow solids can be obtained, which allow water to be reused or comply with government regulations if the overflow is to be discharged.
