stirred mills fluid

Thestirredmilling technologies can be divided into two sub-categories: gravity-inducedstirred millsand fluidizedstirred mills. Gravity-inducedstirred millsinitiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidizedstirred millsuse a rotational movement to fluidize a ...

    Residence Time Distributions in a Stirred Tank Comparison

    Residence time distributions (RTD) are measured for both a baffled and an unbaffled laboratory reactor of the same size with several internal pipes and a Rushton turbine operating at different feed flow rates and impeller rpms. Ideal behavior as determined by the mean and the variance of the RTD was observed at an impeller Reynolds number of 2327 for the baffled tank and 3878 for the unbaffled ...
