A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener ...

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. High rate thickener feed wells are designed to disperse flocculants .

2012-01-12· A paste thickener will require more torque to turn the rake arm and contain more steel than a high rate thickener. Good flocculation remains the key to any successful thickener operation. 1, 3 In addition to this, for paste technology, the thickener would require relatively deep pulp depth, a steep floor slope (as previously mentioned) and mechanical devices to work the compacting slurry.
High Rate thickeners were pioneered in the sugar industry by Enviroclear in the 1980s and operated with a deep feedwell and floc injection into the bed. Developments in thickening technology over the past 15 years have enabled significantly higher underflow densities to be consistently produced. This technology started as an extension of high rate thickening, utilising a deeper mud bed to ...

Platinum Tailings) or feed flow rate (e.g. Clarification or low feed solids). Say, we have a coal tailings application and testwork shows a rise rate of 2 m/h with a pulp feed flow rate of 200 m. 3 /h. Thus, Rise Rate = Pulp Flow Rate Area Thus, Area = π D. 2 = 4 Pulp Flow Rate Rise Rate D = 4 x Flowrate = 4 x 200 π x Riserate 3.14 x 2 = 11.3 Use 12m diameter (b) Torque requirement In order ...
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 applied solids feed rate can now be calculated as a flux - see Eqs. 8a and 8b. Applied flux = G f = (x f Q f ...

A number of significant thickening advances include: Low-profile triangular rake arms to decrease rake torque
High-rate Thickener of Mineral Processing Plant Working Principle The thickener is a machine that separates liquid from solids. It is defined as a method of continuous dewatering of a dilute pulp, wherein a regular discharge of a thick pulp takes place which is of uniform density, concurrently with an overflow of clarified solution.
Ovivo® bridge supported and column supported gravity thickeners provide high sludge concentrations and low solids effluent. The thickener mechanisms are robustly designed for long dependable life and can be tailored to a specific process. Ovivo thickeners can be used in .
thickener underflow cone scraper manufacturer Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet As the particles settle angled rake arms move the concentrated slurry toward the center of the tank where it is removed
The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As ... That the mass balance of underflow pumping and rake arms conveyance will not cause a "rat hole" in the discharge cone or conversely a sludge pile-up. That the density of the underflow will be as high as possible to reduce the load on the disposal .
Our high-rate Thickeners are simple in design and operation with specific benefits for today's producers. After having removed usable materials from the effluent stream, Thickeners recover immediately re-usable process water adjacent to the plant site. Because process water is available at the point of use, not hundreds of yards away, pump is substantially reduced. The smaller volume of ...
