Each type of tank has its advantages and disadvantages. One of the great things about square tanks is that the corners of the tank can act as baffles, allowing for the transfer of the agitator's power to be invested more effectively into the liquid. The imposition of the agitator's torque into the process fluid causes dynamic process response.
Mechanical Agitator Power Requirements for Liquid Batches _____ be described by radial and tangential velocity components. If we assume that the tangential liquid velocity is some fraction k, of the blade-tip velocity then: V u2 = k * u 2 = k * π * D * N ( 1 ) where: V
Paddle, Anchor, or Gate have only 2 blades. These extend close to the tank wall and have tip speeds between 80 to 150 meters per minute. These push and rotate the liquid in a laminar flow. There is no axial or radial mixing. The width of blade is 1/8th or 1/10th of the agitator diameter.
It is affected by product viscosity, blade width, blade speed, blade design, the number of blades, the proximity of the blade to the tank wall and the proximity of the blades to one another. In Newtonian systems (where the shear rate is linearly related to shear stress), shear is a direct function of speed and has no effect on viscosity.
agitator with a turbine or axial flow impeller, and also large diameter ratio axial agitators, e.g. Intermig or double-flux impellers, may be more appropriate (Letellier et al ., (2002)). Intermig is an interference multistage counterflow impeller that has an inner pitched blade and an outer double
The Pachuca agitator is an all-air agitator which consists of a central stationary air-lift pipe in a circular cone-bottomed tank of varying dimensions, usually from 5 to 18 ft. in diameter and 20 to 60 ft. in depth.
When your application requires agitation, Feldmeier engineers will select an agitator to match your processing requirements. Feldmeier offers a variety of agitators designed from mild to aggressive. If your goal is to keep items in suspension, dissolve solids, minimize foaming or aggressive blending to minimize batch times, the staff at Feldmeier will custom design the vessel and agitator for you.

MIXING AND AGITATION Agitation is a means whereby mixing of phases can be accomplished and by which mass and heat transfer can be enhanced between phases or with external surfaces. In its most general sense, the process of mixing is concerned with all combinations of phases of which the most frequently occurring ones are 1. gases with gases.
Agitator shaft is a rotating member usually of circular cross-section which is used for agitation or mixing purpose. Elements such as impeller, coupling, bearing are mounted on the shaft. In design it is usually possible to locate the critical areas, size these to meet the …
Impellers. If there were only one mixing job to do, only one impeller would be required. However, there is a very wide range of problems in agitation, and the best impeller for one application may not be the best impeller for another. The descriptions and discussions below are intended as …
OptiFoil® Agitator Blades. OptiFoil, the newest design of GlasLock blades, combines the advantages of HydroFoil blades and Trapezoidal blades for optimized mixing. The hydrofoil profile improves on the pumping effect given by the standard flat blades of the GlasLock agitation system.
Blades are axial flow agitators, ideal for solid-in-liquid solutions and suspensions because they prevent solid particles from depositing on the bottom of the tank. They can also be used for mixing liquids. Depending on the application, deflectors or flow deflector baffles can also be mounted in the tank. T6 inclined blades. T11 inclined blades
Jul 16, 2015· The agitator should never be run at full speed with the liquid level at the agitator blade level. When the agitator is run with the fluid in the vessel at approximately the same level as the blades, fluid flow can cause the shaft to "skate", resulting in excessive stresses and runout in the seal area and upper end of the agitator.
Jan 17, 2016· Agitaion and mixing 1. Agitation And Mixing 2. Agitation and Mixing Many operations depend upon effective agitation and mixing of components Agitation: induced motion of a material Mixing: random distribution of two initially separate phases A single homogeneous material such as water in a tank can be agitated but not mixed until another material is added to tank
Feb 19, 2020· That is exactly why a quench tank should be twice as deep as the blades quenched for knives. Plunge the blade in and push up and down. No need for a longer tank, all that matters is the first one second. I just remembered another really simple quench tank agitator/circulator. The tank was about 24" high and 4-5" wide.
Agitation and Mixing Processes Introduction Mixing is a process where two or more substances enter a cham-ber where they are combined. The chamber can be a tank, hopper, length of pipe, or even an extruder barrel. Most often, stirring or agitation is the method to combine compounds. The stirring mech-
Mar 10, 2015· If an agitator is center-mounted in an un-baffled cylindrical tank, it produces a swirling motion, which is very inefficient. As an example, imagine two particles swirling in a circular motion, they will always be chasing each other and will not mix.

An agitator is composed of a drive device ( motor, gear reducer, belts…), a guiding system of the shaft (lantern fitted with bearings), a shaft and impellers . If the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is ...
(blade width, blade angle, number of blades and so on.). The primary flow generated by an impeller is calculated from Equation (2): Q=Fl N D3 (2) Fl is the impeller's flow, or pumping number. Both the power and flow numbers are measured ex-perimentally and typical values for …
