The thickener plays a crucial role in achieving the desired texture of the product. For e.g., a thickener that imparts a luxurious and velvety feel may be preferred for high-end creams. Whereas, a lightweight and non-greasy texture may be desired for lotions. The chosen thickener should align with the desired texture attributes of the formulation.
A Thickener by definition produces thick mud - but how thick is enough? This is often best considered with reference to a Yield Stress Curve with yield stress in pascals plotted against underflow density. The yield stress is a subset of the enormous topic of rheology and is commonly used in Thickener design to represent the force required to

— Cornstarch is a common thickening agent in the culinary arts, but if you add it directly to the liquid you want to thicken, it will clump up. To thicken a sauce or soup with cornstarch, you first need to make a slurry, which is a mixture of equal parts cornstarch and liquid (usually water, stock or wine). It's important to make the slurry with cold liquid, and …

The characteristic features of a High Rate Thickener, which distinguishes it from a Conventional Thickener, are: Deeper feedwell; De-aeration of the feed (either internally in the thickener or external to it) A means of deflecting the feed from the vertical & distributing it within the body of the thickener; Controlled bed level
— A cyclone used in washery practice can be looked at from different viewpoints. The particle size of the suspension or the specific gravity of the particle. introduced into the cyclone, or both, may be the physical property for which a separation is required. In the first case we have a cyclone thickener, where a suspension in water or …
This thickener is designed to be easy to mix and dissolve, making it an ideal option for those who want to save time without sacing quality, however, it may take awhile to get it mixed in all the way. Additionally, Thick & Easy comes in a variety of flavor options, allowing you to customize your thickened drinks to your liking. When it ...
The ease by which thickeners are effectively dispersed or dissolved in the solvent chemically depends on particle size, molecular weight and structure (average number …
One English colliery has used a cyclone to thicken coal slurry, and as it appeared that the Netherlands-type cyclone might have wide application as a thickener for coal slurries in …
The primary purpose of a thickener is to allow enough settlement time for the dirty water to be cleaned and then reused in the system. All Parnaby thickeners have a special profile and an internal moving rake which is designed to achieve rapid settlement of solids in water. The unique design maximises the efficiency and significantly aids the ...
— If the thickener's underflow is destined for a tailings dam, the optimisation of the slurry density helps to reduce negative environmental impacts through leaching at the dams. Bed mass is calculated based on the total volume of combined water and solids in the tank and the total hydrostatic pressure measured near the bottom of the tank. As ...
— Although the cyclone thickener has been dealt with in three reports by Driessen, its use as a thickener was not the principal subject of any of these reports and therefore neither the cyclone itself nor its …
— The cyclone underflow returned to the ball mill and cyclone overflow passed over the trash screen prior to adding to the pre-leach thickener. The mass rejection from the limonitic ore was typically 50%, with a corresponding increase in …
Sludge is pumped from the primary clarifiers to the cyclone grit separators. The grit removed by the two separators is dewatered before disposal. The de-gritted primary sludge from SEP 1131 flows to the mixed sludge distribution chamber, where it is mixed with WAS and conveyed to the center feed well of the gravity thickener. Secondary effluent may

Cyclone Technology. He says cyclone technology is now replacing bucket wheel technology as a "natural evolution" of materials processing brought about by modern innovations. CDE has developed cyclonic materials technology to the point where it guarantees the removal of the undesired fraction (e.g. -74 micron) while retaining quality fines ...
— Cyclone selection methodology and modelling-simulation helped to select the geometry of pilot scale unit. ... In this operation, the tailings are initially sent to thickener and then mixed with cement-water mixture prior to its use in the underground mining. Data collection aimed at testing of varied cyclone geometries to define the limits of ...
— For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure …
For desliming purposes, normal classification takes place in the upper portion of a cyclone; this can be thought of as the first stage of desliming. The CycloWash, located in the lower/apex section of the hydrocyclone, …
particle-to-particle interactions between thickener and charged surfaces of system components bring about changes in rheological properties. The ease by which thickeners are effectively dispersed or dissolved in the solvent chemically depends on particle size, molecular weight and structure (average number and
