Thickeners — Types, Working Principle & Applications

Aug 08, 2018 · The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well placed up to 1 m below the surface of the suspension. ... Types of thickeners…

Continuous Thickening Theory

In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U.

How a Thickener Works - Mineral Processing & Metallurgy

Attempts to make thickening continuous, by using hopper-bottom tanks or cones, were not entirely successful. In these tanks the feed ran in continuously, settled solids were drawn off through a spigot and solution overflowed continuously at the top of the tank. ... How a Thickener Works. Previous Next ...

Conventional Thickeners

Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters or centrifuges. Historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in Australia.


Rake driven thickeners for continuous operation can impose a substantial burden on capital investment. Unlike many other types of equipment, thickeners have no stand-bys so if one goes out of commission it cannot be by-passed.

Thickening - Resource Book

Continuous thickeners have undergone several modifications that have resulted from the development of a wide variety of organic polymeric flocculants. As a result, there are now two basic types of continuous thickeners: Conventional and High-rate. Conventional Thickeners These thickeners differ in the way they are built.

THICKENERS - Thermopedia

A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a …

Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids.

Measuring Settling Rates and Calculating Thickener Capacity

In a continuous thickener, the four zones previously described in discussing intermittent settling are generally present as shown in Fig. 2. At the top there is a zone of clear water, A. Beneath this is zone B, consisting of flocculated pulp of uniform consistency.

CHAPTER 3 SLUDGE THICKENING - Marmara Üniversitesi

CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content

Thickeners - Mineral Processing & Metallurgy

Thickeners, equipped with the patented spiral scrapers and angle rakes are a distinct improvement over all types of mechanical raking devices now in use. Specifications and thickener rake design All Thickeners have the same general specifications, varying only as to type of machine. The specifications given for one will cover all.

Thickener Operation - Zeroday Enterprises

Jan 26, 2015 · c) Under flow pump: which can be of several types including peristaltic, centrifugal, diaphragm and progressive cavity. Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener.


A GUIDE TO UNDERSTANDING AND MIXING THICKENERS Rheology modifiers, commonly referred to as thickeners or viscosifiers, are ever-present in most products. The use of these additives cut across several process industries including food, pharmaceuticals, cosmetics …

Thickeners - Article - FineCooking

Flour is the most common thickener used in recipes, from turkey gravy to apple pie, and for good reason: It’s versatile, and in most kitchens, it’s always on hand. But stone isn’t a pure starch (it contains protein and other components), so it has only about half the thickening power of other starches.

FSM H06 CS5 -

fundamentals of settling the distribution of types and shapes of particles in FS (and their respective settling velocities) could theoretically be used to design settling-thickening tanks. Although this theory is important in understanding the design of settling-thickening tanks, the reality is that
