One of the most important requirements to liquid – solid mixing processes is prevention of sedimentation of solid particles on the tank bottom. Therefore, one of the main tasks of a designer is to provide Just Suspension Speed (JSS) that is the minimum rotational velocity of the impeller at which there are no stagnant zones at the bottom.
A liquid – solid mixing process is carried out in a cylindrical, baffled tank with an elliptical bottom. The parameters of the mixing system are as follows:
Properties of the media:
NOTE: Change the density and viscosity input data by VisiMix recommended.
VisiMix Turbulent for mathematical modeling of turbulent mixing in reactor with 2-stage Lightnin impeller.
You will obtain some general data on your mixing equipment, which will enable you to evaluate the general suitability of your equipment, compare different designs, etc. These parameters are used as basic data for calculations of other mixing problems.
