Product Description:

Thickening is the separation of suspended particles from a liquid by gravity settling and A thickener is a machine that de-waters slurry, separating the liquid from the solids. In fact, most mineral-refining processes go through a solid-liquid separation in a thickener at some point in their processing. As a result, Improvement of the working efficiency of thickening process can have different beneficial outcomes, water utilization during the process, lowering the costs of energy and flocculant and reaching the optimized separation limit.

In order to achieve the highest performance in a thickener, there are many critical key performance indicators and variables – all of which need to be measured accurately and reliably.

A good controlling system should be able to stabilize and optimize thickener performance. Higher performance of a thickener can be reached by:
• Precise control of feed flow
• Optimization of flocculent dosing
• Precise measurements of slurry underflow and overflow rates and their correlation
• Accurate online calculation of solids content
• Online calculation of bed pressure and height

Working Principle

Working Principle

Thickeners are comprised of a tank, feed pipe feedwell, rake (and pickets, depending on the thickener style), a bridge containing the rake drive mechanism, and a chemical dosing system.

The slurry feed enters the thickener from a de-aeration tank and into the feedwell. Chemicals are added to the feed to aid in rapid settling of the solid particles in the slurry. These chemicals can be flocculants or coagulants, depending on the application. They attract the fine solids in the slurry to form larger, heavier particles that sink to the bottom of the tank.

As the flocculated solids settle to the bottom of the tank, the rotating rake mechanism assists with moving them toward the discharge cone in the center. The thickened solids are then discharged out the bottom of the tank and, depending on the application, sent to waste or further processing.

The solids-free liquid (or liquor) overflows the weir surrounding the top of the tank. Again depending on the application, this clarified liquid is then sent for further processing or reuse as process liquid

Benefits:

Advantage:

Optimised underflow density for solid-liquid separation

Thickeners work on the operating principles of gravity and particle interactions, with solids settling downwards and liquids rising to the top as they separate. Whether you choose a High-Rate Thickener, a Deep Cone Thickener or one of our other solutions, we'll utilise all our process and materials expertise to optimise the underflow to meet your needs and achieve solid-liquid separation at the desired density, clarity and rate.
