High Rate Thickening is a process whereby mineral particles are flocculated, thoroughly mixed within a feedwell and then injected uniformly into a hindered settling zone in the thickener with largely radial motion.

The AltaFlo™ is a rakeless thickener that uses rapid dewatering in the hindered settling zone to achieve a very high settling rate. The AltaFlo typically operates at twice the settling rate of a high rate thickener. The geometry of the unit provides for a deep compaction bed, allowing the thickener to achieve relatively high

In turn, the dewatering techniques becomes more complicated moving from high-rate thickeners for lower solids concentration tailings underflow to high-density thickeners and deep-cone (paste) thickeners. For further dewatering, …

Thus, Paste Thickeners are commonly run at a higher rise rate than a conventional or High-Rate Thickener (either using more flocculant or accepting more solids in the overflow), giving the appearance of having a higher capacity.

Describe the objective, principle of operation, and principal components of a conventional thickener. Describe the objective, principle of operation, and principal components of a high-rate thickener. Explain why the mass flow rate of solids into and out of the thickener should be equal. Identify the typical zones found in an operating thickener.

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.

The AltaFlo ultra high-rate thickener is a rakeless thickener providing mixing, flocculation, and internal dilution. The AltaFlo also provides clarification and positive sludge collection and removal in a single tank. The AltaFlo typically operates at twice the settling rate of a high-rate thickener.

PHOENIX - AF AltaFlo™ - Ultra High Rate Thickener by PHOENIX Process Equipment Co.. PHOENIX has long been a market leader in separation, classification, thickening, and dewatering equipment for the aggregate industry.

This normally occurs in the hindered or compression zones. The area requirements for thickeners are frequently based on the solids settling rates measured in the hindered or zone settling regimes, where the settling rate steadily decreases as the particle concentration increases.

PHOENIX HiFlo High-Rate Thickener. OENIX HiFloTMHigh-Rate ThickenerThe PHOENIX HiFloTM Thickener clarifies the water while it thickens the slurry from a wash plant to 40-45% solids, greatly reducing th. volume going to the slurry pond. For complete elimination of the slurry pond, a PHOENIX Belt Filter Press or Recessed Chamber Filter Press may ...

WesTech paste thickener design allows for increased performance compared to conventional or high-rate thickeners. A smaller footprint, increased water recovery, and paste/thickened tailing underflow translate into great advantages.

1 Introduction. Eleven years after the development of the continuous thickener by Dorr in 1905, Coe and Clevenger described and classified the sedimentation process under static batch settling conditions into four zones from the top down i.e. a clear water zone; an initial slurry concentration zone; a transition zone and a compression zone (Coe ...

Thickeners are utilized in various solid/liquid separation processes in order to increase the density of a process stream. Feed solids concentration is the single most important variable affecting the sedimentation properties of given slurry. High-rate thickener. ANDRITZ process engineering will determine the optimum percentage of feed solids ...

Magrabrators induce resonance through vibration for optimum underflow density and extended free settling zone by lowering the compaction zone height dramatically. The advantages. Density increases can be measured within minutes. Eliminates rat-holing in the compaction zone bed. Extends the compaction zone by producing a higher density …
