May 04, 2014 By Gregory T Benz, Benz Technology International, Inc Though most process tanks are agitated by means of a mechanical agitator, comprised of a rotating shaft and one or more impellers, occasionally process engineers will ask, Why cant we just use a pump, instead of an expensive agitator? This paper attempts to answer that question by comparing

Mixing: Impeller performance in stirred tanks Impeller Performance in Stirr ed T anks IN BRIEF The importance of accurate measures of agitator performance that can be used in the

The more commonly used measure is turnover time, which takes tank volume and divides by pumping rate to establish how long it takes to move the entire tank volume once Obviously, one tank turnover is probably not sufficient for any practical mixing requirement Somewhere between five and ten tank turnovers may be sufficient for simple blending

Single phase turbulent flow in a tank stirred with two different axial impellers a pitched blade turbine PBT and a Mixel TT MTT has been studied using Laser Doppler Velocimetry The effect of the agitator configuration, i e up pumping, down pumping and reverse rotation, on the turbulent flow field,
