Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.
Outotec® Thickening technologies Leading edge technologies for thickening and clarifying Outotec is a global leader in the design, fabrication and supply of thickening and clarifying solutions for the minerals industry. The revolutionary Outotec® High Rate Thickener has pioneered and redefined thickening and clarifying methods around the world.
High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below.
Thickeners: How they Operate. The most common solids-liquid (S/L) unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low % solids waters.

Emma Griffin charts the postwar emergence of working-class history as a scholarly discipline and argues that, thanks to the torch-bearers, the rationale for it , When history emerged as a scholarly discipline in British universities at .
A Critical Review of Thickener Design Methods t F. Concha and A. Barrientos Department of Metallurgical Engineering University of Concepcion* Abstract In this work we analyze, in the light of their physical foundation, the different methods of thickener design that have been proposed in the literature.
Working Principle This ore thickener machine consists of round thickener and harrow scrapping machine, the solid particles suspend in thickener settling by gravity, the pulp in the upper turn into clean water, so that the separation can be realized.
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 …
Sep 13, 2013· gravity to the thickener and shall have the energy to aid mixing of flocculant solution with it. The feed well is sized adequately to take care of the venting of the entrapped air in the feed slurry.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in …
There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet.
Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease's consistency is its resistance to deformation by an applied force. The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by handling or working.
How a Thickener Works. ... One tall thickener thus does the work of several relatively shallow thickeners of the same diameter. Floor space is conserved, heat insulation is simple and effective, and power is reduced. Furthermore, all control of the washing operation is centered at a single point.

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 …
This work presents an intelligent control based on an expert system applied to an industrial 125 m diameter thickener, processing 13000 m3/h of concentrate containing a 27 % of solids.
Jan 26, 2017· The thickener in a lubricating grease is the component that sets grease apart from fluid lubricants. Thickeners are molecules, polymers, or particles that are partially soluble in lubricating fluid; they arrange themselves in such a way that they impart a semi-solid consistency to the grease.

thickener for acrylic-based binders and nonwoven fl ock adhesives commend it for thickening textile backcoating and laminating formulations. It is compatible with many fi llers and effective at low concentrations. Textile Carpet Dyeing and Printing In carpet dyeing, such as the Küsters continuous dyeing system, very few thickeners
Mar 06, 2018· Thickening tanks have slow-moving vertical paddles. Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base.
The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed. Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3.300.000 Nm.
