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.

When it comes to managing tailings, producers have a variety of equipment options to help them reduce the volume of slurry material reporting to the settling pond or tailings storage facility (TSF). One of these options is a Thickener, a liquid-solid separation device that can be used alone or as part of a larger tailings management system to …

restricted to relatively high effective feed fluxes and consequently there was poor agreement with continuous tests at low feed fluxes. The flux curve determined by the method of Coe and Clevenger was invalid for all feed fluxes. A case study shows how the required thickener area would vary for a number offine coal processing options.

The thickener is a 2 m diameter by 2 m high sidewall tank with a 14° floor and a small discharge hopper (45° slope). This "thickener" is not used as a sedimentation and dewatering tank in the experiments reported here; instead it plays the role of a throughflow holding tank in which the raking experiments are undertaken.

Laboratory tests and plant operation have also established that a well-aerated pulp settles better than one in which aeration is incomplete. ... Mines, Ltd. A water-soluble "H.V." grade used in the amount of 0.01 lb. per ton of ore increased the settling rate in the thickeners by 8 to 10 per cent. by L D Michaud February 29, 2024 July 13 ...

Design of thickeners is based on laboratory test work, characterizing the material and determining the optimal reagents, dosages and settling regimes. Several methods for dimensioning plant scale equipment exist. Kynch and Talmage-Fitch design procedures has been applied widely for a long time. Nowadays, besides them, a …

The HI-RATE THICKENER is a MechProTech OEM product manufactured in-house. It has a structurally grated walkway across the top. ... To aid settling and thickener performance, MPT can install high circulating pumps to increase supernatant back into the feed stream to improve the thickener's floc generation and settling performance.

Wa has been designing and engineering thickeners since 1965 for a range of industrial and mining applications. Wa's designs are backed by our own laboratory capability and pilot thickener plant allowing Wa to continually develop state of the art technologies for specific applications. Wa offers conventional thickeners, Hirate …

High-Rate Thickeners can be supplied with flat-bottom, on-ground tanks or elevated tanks, which feature short suction lines that reduce the risk of plugging. ...

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 ...

Laboratory testing with a high rate thickener has shown the importance of feed solids control to thickener and flocculant performance (Table 4). In the preoxidation as well as CCD thickeners, testing has demonstrated that an optimum feed solids level can be attained which will maximize thickener performance while minimizing flocculant …

High compression thickeners Achieve a higher density underflow with our High Compression Thickener.
