Deep Cone paste thickeners for ultimate underflow solids concentrations EIMCO Deep Cone paste thickeners produce underflows concentrated to near their limit of pumpability. The deep tank design maximises pulp concentration, and produces uniform, non-segregating underflow slurry with a paste consistency. Paste/high-density thickeners

In this case 10 cubic feet times 3 equals 30 cubic feet or 225 gallons. The total cycle of the press would be less than 2 hours. If the concentration is on 0.5%as from a typical cone bottom clarifier, the volume would be 60 times or 600 cubic feet – 4500 gallons and the cycle time for the press may be 20-30 hours

Footprint can become a significant CAPEX consideration when excavation costs are elevated. To illustrate, we will assume our high-rate thickeners in Table 8 cost $1 million each. Therefore, all thickeners for the high-rate option would be $5,000,000 and for the deep cone option $6,800,000; or $1,800,000 more

Oct 21, 2016 The feed enters at the centre of the tank as in the other type, clear water overflows into a peripheral launder, and the revolving blades scrape the settled solids into a discharge cone. Central Drive Thickeners are made with tanks ranging from 6 to 100 ft. in diameter, but the larger sizes are not as a rule employed for concentrates, the Traction Thickener being preferable for diameters in excess of about 50 ft.

What is a Deep Cone Clarifier? | ChemREADY Click to learn

Deep Cone Clarifiers, or decanter clarifiers, are a type of vertical thickener used in the wastewater clarification process. Unlike the filtration carried out by the filter press, the clarification is a continuous process that separates water from the solid particles suspended into it. Matec can provide customers with any type of decanters, by designing and manufacturing vertical and horizontal ones made of stainless

AltaFlo™ High Rate Thickeners

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

Proper thickener underflow densities - FLSmidth

Proper thickener underflow densities - FLSmidth

Proven thickeners that deliver desired underflow density. Thickeners work on the operating principles of gravity and particle interactions, with solids settling downwards and liquids rising to the top as they separate. The design of the thickener focuses on providing a high-density underflow while maintaining an acceptable overflow clarity

High Rate Thickeners - Solid Liquid Separation

High Rate Thickeners - Solid Liquid Separation

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

Q+R = total flow to the clarifier 1.5 = scale-up factor 7. Determine the area required for clarification (A c) Q = the effluent flow over the weir (same as above) 2.0 = scale-up factor Whichever area is larger will govern the design and will be the design area. Second Approach Second approach in the design of thickeners is the solids flux
