I have a question regarding the selection of stirrers
Thread Content
A 100L reactor has been built now, using an anchor-type stirrer made of PTFE, but the results are not satisfactory. The product being manufactured is a coating that requires uniform mixing at a scale of 100 nanometers; are there any recommended impeller designs for this purpose? Thank you!
The anchor paddle operates at low speeds and is used to prevent materials from accumulating at the bottom of the tank； The poster did not specify the density of the working fluid or its relative density to solids; however, since the particle size of the solid phase is small, the type of impeller should be chosen based on the requirements for dispersion. Personally, I would recommend a double-layer open 45° turbine impeller, as it provides both radial and axial dispersion effects. It’s not clear whether there are baffles in the 100L tank – if there are, the dispersion effect will be even better. The rotation speed should be somewhat high, but since no parameters are provided, it’s impossible to calculate exactly; only the direction can be suggested.
Agree with the opinion on the second floor: use folding turbine blades, and install a speed control motor to regulate the rotation speed.
