The Outotec FrothBuster deaerator reduces the amount of froth forming on the surface of thickeners and our innovative Outotec Vane Feedwell incorporates interconnected upper and lower zones to further improve performance. Uses flocculation chemistry to dramatically increase settling rates 0.35-1.5 tm2h Offers consistent and high ...
These impellers include the axial flow impellers, hydrofoil impellers, pitch blade turbines and radial flow back swept impellers. The axial flow and hydrofoil impellers were the most recent introduction in terms of mixing turbines in the industry duet to their high pumping number Nq and low power number Np.
Agitation Tank is mainly used to mix pulp before flotation in the beneficiation process. It can mix drug and pulp intensively. Agitator is suitable to mix pulp with density smaller than 30 weight ratio and size smaller than 1mm. V-belt of motor drives impeller to mix drug and pulp completely.
High-rate solids contact clarifier combines optimized flocculation, internal and external sludge recirculation, to achieve very high hydraulic loading and treatment efficiencies. It is effective for lime softening of ground or surface waters, tertiary treatment of wastewater, and precipitation of metal hydroxides from waste streams.
The P3 agitator impeller is also known as a high solidity hydrofoil impeller like the P4 impeller but with three blades instead of four. These types of impellers are used in applications where a macro flow is required, specifically in high viscosity, low Reynolds number fluids.
Viscosity plays a significant role in creating an optimal mixing system. By switching up the agitator impeller design, size and shape of the mixing vessel, and mixing speed, we can create precise mixing solutions, no matter what kind of viscosities are involved.In this installment of Mixing Basics, were breaking down viscosity, an often misunderstood piece of the mixing puzzle.

The new larger mixer has a higher maximum impeller zone shear rate, which is estimated at 1.4 times as high as a small unit at the same DT ratio. Assume that this higher shear rate has cut the productivity of the increased cell concentration to 90 of its normal value.
Very high viscosity mixing is addressed with square blades and anchor paddles. Compatibility with stirring equipment. Confirm the diameter of the shaft to be used fits the chuck of the overhead stirrer. If the impeller needs to be attached to a mixing shaft with a
Apr 07, 2006 Averaged shear rate at the impeller outlet The averaged shear rate of the ow at the impeller outlet can be related to the impeller pumping ow rate K S N VD QD2 D where N is the shaft speed, V is the impeller exit velocity, D is the impeller diameter, Q is the impeller pumping ow rate, and denotes averaging. Given that Q 3N Q ND ...
Apr 01, 2005 For these purposes, anchor impellers, in which the blades rotate very close to the wall, are suitable. In addition to this, high shear stresses are present in this type of close clearance impeller, which lessens the apparent viscosity of pseudoplastic fluids and improves mixing Tatterson, 1991 Pedrosa and Nunhez, 2000.
Feb 05, 2016 Wetted and aged flocculant from the mix system is transferred to a 2.75 meter diameter x 2.75 meter high flocculant mix tank on an automatic regular basis at a rate of 1200 litres per batch, at a concentration of 0.5, where it is further mixed and aged.
By recirculating settled sludge from near the bottom of the basin, the sludge blending thickener of the invention is constantly mixing high-solids sludge with liquid of much lower solids concentration, thus blending the higher and lower solids liquids to provide, in the settled sludge blanket at the bottom of the basin, a substantially constant ...

Thickeners and Clarifiers. DELKORs thickener is a proven performer across a variety of applications ranging from the mining and minerals industry to industrial, chemical, water treatment and wastewater industries. With units of up to 100 m in diameter having been installed, the benefits of our DELKOR conventional, high-rate, high-density and ...
A typical emulsion mixing process begins with heating the water phase and water soluble ingredients to 7580 C, depending on the procedure. This may include premixing a thickener such as xanthan gum with glycerin, which is then added to the water and other ingredients. In a separate vessel the oil phase is also heated 7580 C, which can ...
Mar 15, 2021 A higher rate of energy dissipation and mixing was observed at a high rotor speed.

New methods for liquid-liquid and gas-liquid dispersions in laminar, transitional and turbulent flow are provided. Micromixers are preferable for high rate of heat and mass transfer applications, and when specific product properties are requested. A fundamental description of mixing and transport in micromixers is provided in Section 7c.
Quick Shop 2 Axial Flow Turbine w 38 Bore LIMA20375 50 316 SS. The axial flow turbine is a classic medium shear impeller. Very effective in both low viscosity and high, this axial mixing blade allows a mixer to the break up agglomeration and impart solids effectively.
Feb 12, 2008 A further contract that has recently been awarded is for the design, supply, installation and commissioning of six high rate thickeners and clarifiers. The project is for a prominent platinum producer on its most recent mineral processing complex in the Northern Province, South Africa. The plant is due for commissioning in July 2007.
rate of mixing at any time under constant working condition ought to be proportional to the extent of mixing remaining to be done at that time RATE OF MIXING where M is the mixing index and k is the constant and on integrating form t0 to tt during which M goes from 0 to M,
As can be seen from the equation, at a given horsepower, a relatively high mixer speed and small impeller diameter will result in lower torque and therefore a lower mixing level than a larger impeller turning at a lower speed. Impeller Styles Mixing impellers fall into one of
When Mixing Matters Choose Impellers Based on Process Requirements, by M rcio B. Machado and Suzanne M. Kresta of the Univ. of Alberta July 2015, pp. 2733, points out that while power number is impor-tant when selecting an impeller, other factors, including bulk flow, turbulence at the impeller, and mixing condi-
Radial Flow Anchor - An impeller designed for mixing higher viscosity products. An anchor is normally U shaped, and follows the contour of the tank. Anchor impellers are specifically designed to fit the process. Anchor impellers are used to sweep the entire peripheral area of a tank - both walls and bottom.
