Based on the impact on rake operation of different height and concentration of tailings in the thickener,the stress of rake was analyzed,and a torque model with complex structure rake was proposed.According to the actual phenomenon,the thickener was divided into two zones,the fluid zone and granular zone considering material's distribution in the …
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).
Maximising thickener underflow density has advantages in many of the traditional thickener applications. There is a long history of innovations in thickener design to enable the production of higher densities. Large High Density thickeners were pioneered in the late 1980s. The roots of Deep Cone thickeners go back to the 1960s.

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 ...

The deep cone thickener shown in Figure 1.5 is again broadly similar in form to a conventional thickener, but the sides of the inverted cone have a much steeper angle, in the region of 37°. Units are available with diameters up to 15 m to process suspensions at throughputs as high as 70 m 3 h −1 .
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.
To illustrate the differences between these thickener types. Figure 18.5 depicts underflow produced by the thickener compared with the relative yield stress of the material. High-rate thickeners produce …

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.
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.
The term "conventional thickener" refers to those tanks with a shallow base slope and a relatively shallow depth of sediment, and is the type of equipment that is the focus of this study. Material that settles in a conventional thickener moves towards the discharge partly under the action of gravity and by mechanical transport using rakes.
