A high-rate thickener or paste thickener dewaters the tails (waste) before disposal in a tailings pond, or as a paste deposition. To learn more about options for CCD thickeners, read our blog post titled Maximize Precious Metals Recovery with CCD Circuits and High-Density Thickeners .
The PHOENIX AltaFlo™ Thickener is a rake-less thickener that provides ultra high-rate mixing, flocculation, and internal dilution followed by clarification and positive sludge collection and removal in a single tank. The Thickener's unique internal geometry, a deep sidewall and steep conical bottom provides underflow concentration comparable ...
Lower-yield stress muds, as produced in a high-rate thickener, require less torque to move rakes through the mud. As the underflow solids concentration increases from high rate to paste thickener, the yield stress increases. In rheology, the yield stress is the minimum amount of shear stress required to initiate and sustain flow (O'Brien ...
High-Rate Thickeners, or Clarifiers, recover immediately reusable process water for mineral and aggregate producers, as well as environmental contractors. Thickeners are beneficial in a variety of applications, including areas where water is in short supply or very expensive, re-circulated water is not suitable for reuse in a plant, ponds are located on minable reserves, or ponds must be ...
High Rate Thickeners 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.
PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the process.
The thickener area is also required for this calculation. Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a circular thickener with a 15.24 m (50 f t) dia.: A= Pi r 2 = 182.4 m 2 (7)
The thickener mechanism generally will have more robust rake design with increased torque capacity compared to a high rate thickener with the same diameter (Bojcic, 2000). The rake torque factor can be three to four times higher and will vary with underflow density according to an empirical relationship that depends on rake shape and drive ...

Mar 14, 2017· Diluted slurries, once flocculated, settle more readily than undiluted slurries. AltaFlo's increased bed depth increases the compaction of thickened material...
The Titan™ traction thickener processes very high throughputs in a single thickener and cost-effectively provides greater torque in large units. When sizing a high-rate thickener, one factor that limits the size and throughput in the unit is the available torque. This is particularly true with center-driven, high-rate thickeners.
PHOENIX has long been a market leader in separation, classification, thickening, and dewatering equipment for the aggregate industry. One recent innovation is the AltaFlo Ultra High Rate Thickener, featuring: No moving parts. Minimal space requirements. High underflow solids (as high as 50-60% in mining applications).
In order to develop rational methods of measurement and laboratory testing, it becomes necessary to study the general phenomena of settling rates. Since it was desired to give the public the benefit of these methods at as early a date as possible, together with the knowledge of the general principles of slime settling necessary for a clear understanding of the laboratory tests, we have ...

Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow ...
Paste Thickeners can help producers eliminate the need for settling ponds and other structures. They are meant to achieve the highest solids concentrations possible through gravity separation. The resulting mud, described as a paste, is often so thick that it becomes non-segregating — no further separation of water and solids can be achieved. As a guide, a paste material is measured with a ...

The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of ...
AltaFlo ultra high-rate thickeners perform well as tailings thickeners, in CCD circuits, as concentrate thickeners, and in leaching circuits. The low CAPEX economics of an AltaFlo also make it a perfect solution for dewatering non-profit streams. The heart of any thickener or clarifier is the feedwell.

In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.
