Evaluation of Mixing Performance of Large Paddle Impeller HRX300

Abstract

HRX300 has high mixing performances and promotes the evaporation by splashing liquid from the free surface. The mixing performance was evaluated by measuring mixing time, power consumption and volume of splashed liquid. The dimensionless mixing time of HRX300 was equivalent to that of Super-Mix MR205 under turbulent flow conditions. The power number of HRX300 was correlated by the same equations as Super-Mix MR205. Furthermore, HRX300 was found to have a high splashing performance at most liquid depths.
