Is it better to increase the blade diameter or the rotational speed?
Thread Content
Kettle DN1800, two liquid phases; viscosity 60–100, density 1.2. A solid is formed as a result of the reaction, accounting for about 1/3 of the total mass. Axial flow mixing using airfoil-shaped impellers, with a rotation speed of 110. The original design did not provide good mixing effects. For a tank like this whose purpose is merely to achieve mixing, should I increase the rotation speed or the diameter of the impellers? What is the maximum blade diameter that can be used for the tank of DN1800?
The viscosity is high; it is recommended to increase the blade diameter. The scraper blades are almost as wide as the diameter of the inner cylinder.
The diameter of the blade was increased to 1000mm
