How to select an impeller
Thread Content
Since I’m new to this field, I’ve looked at the specifications for mixers but don’t understand how to design the mixing blades For the up-and-down circulating flow mode, options include screw rods, screw belts, and anchors – which one should be chosen? :(
This mainly depends on your process requirements and reaction characteristics!
What are the differences between screw rods, screw belts, and anchors? The manual doesn’t provide details
It is determined based on your reaction time and the viscosity of the reactant material. The shape and rotation speed of conventional mixers are fixed, with corresponding standard parameters; the rotation speed of anchor-type and frame-type mixers is 85 revolutions per minute, while that of impeller-type and paddle-type mixers is 130 revolutions per minute. Moreover, the mixing locations vary. You can choose according to your own situation.
Determined by the viscosity of the reaction materials. Anchor type is used for ordinary materials.
Use a propeller drive with guide vanes. Alternatively, use a folding paddle.
I have a paper on the selection of stirrers; send me your email and I’ll send it to you.
The selection of impellers depends on the physical properties of the material and its intended use; there are radial impellers and axial flow impellers, among others. Each case must be analyzed individually, as discussed in the section on mixing equipment
The choice of impeller type depends mainly on the composition and viscosity of the material to be stirred. Once the mixer is selected, its speed and power can be calculated using empirical formulas
