On-line measurement of slurry rheology in a thickener …
category, the viscosity of a pseudoplastic slurry is lower at high shear rates and is, therefore, easy to pump. On the other hand, viscosity of a dilatant slurry increases with shear rate and can pose serious pumping problems. Therefore, in a thickener operation, a pseudoplastic product slurry is desir able over a dilatant slurry.

The flocculation that takes place in the central feedwell of the thickener plays a crucial role in the coal-slurry thickening process, which is not only complex but also largely influenced by the ...
Lesson 11: Sludge Thickening Objective
is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume.
Beginners guide to thickeners
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.

Effect of feed solid concentration on tailings slurry flocculation …
Thickeners have been widely applied in the solid-liquid separation process, such as wastewater treatment and tailings slurry thickening process [1], [2], [3]. The principle of a thickener is simple: a feedwell generally receives the tangential feed stream and then transform it to a slow vertical downward flow to the body of the thickener.
High Capacity Thickener
Conventional practice is to add flocculant as a dilute solution to the feed slurry in a launder or feed pipe, possibly using staged addition so as to improve the floc growth. Mixing in launders is not necessarily optimum, and with deep launder pulp depths lower layers of slurry do not readily rise to the surface and become contacted with reagent.
How to Thicken Sauce and Soup (Cornstarch Slurry)
And make sure to whisk the slurry until right before you are pouring it into the sauce/soup. 2. Add a slurry small amount at a time. Instead of pouring the slurry all at once, add gradually and check the consistency before adding more. 3. Constantly mix with a spatula or ladle after adding the slurry
