HIGH-RATE THICKENER. High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

HiFlo™ High-Rate Thickeners WesTech HiFlo thickeners are used to separate solids from liquids at high flow rates. These rates are 10 to 20 times higher than those of conventional thickeners. AltaFlo Ultra High-Rate Thickeners The AltaFlo ultra high-rate thickener is a rakeless thickener providing mixing, flocculation, and internal dilution.
Conventional Thickeners - Solid Liquid Separation. The Cone Scraper . Underflow Pumping. Pumping of dense underflows has always been a problem on thickeners that handle slurries such as metallurgical concentrates, potash or phosphate and the position of the pumps in relation to the discharge cone can be very critical.
In this case the pattern would be a deep cone thickener equal to the existing paste thickeners, having dimensions of 10 meters in diameter and 14 meters high in the shell side, which had a scraper mechanism, and which was obtaining a solids content of 30 to 21 underflow in wt% compared to 15-17% obtained in conventional thickeners.

We investigated the axial and radial solids concentration distribution at discontinuous state in a pilot deep cone thickener as a function of bed height and residence time. The feed flux of lead/zinc tailings was 0.254 t·h −1 · m −2 with a flocculant (high molecular weight anionic polyacrylamide) dose of 20 g/t. The thickened solids bed ...
There are two basic types of high rate thickener units: Lamina or tube settlers and solids recirculation units Lamina Thickeners They contain space-cutting baffles that intercept settling paths at many levels. Solids settle out onto the baffles and are removed from suspension after settling only a short distance. Where and to the extent …
The Conventional Thickener. Description. Conventional Thickeners are generally incorporated in heavy duty applications when the underflow …
A key component of most thickener operations is the motion of a thickened sediment across the floor of the tank to an underflow, usually located centrally. In most conventional thickeners and in many high rate and paste thickeners, this transport is aided by a set of two or four rake arms (see the schematics in Fig. 1, Fig. 3).
Thickeners are often rated on lbs. of solids per square foot of surface area. Briefly, its functioning can be explained with Scraper blades or "rakes" that are used in a thickener, which rotate slowly over the bottom of the tank, and slope down towards the centre and move the material settled on the bottom to a central opening or discharge.
Deep Cone™ thickeners are now in operation, producing pastes of over 70% solids, suitable for both mine backfill and surface stacking. This paper will review the theory, technology and operational performance of the Deep Cone™ thickener.
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.

The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.
