This paper deals with the scale-up of equipment for the mixing of suspensions. The measurement of just-suspended agitator speeds was carried out with standard, pitched, four-blade turbines and folded, four-blade turbines in three vessels (290 mm, 600 mm, and 800 mm in diameter) for several particle sizes and concentrations. The results of measurements confirmed that scale-up based on dimensionless Froude number dependence, on the relative particle size and concentration, can be used. On the basis of the results, a scale-up rule for agitator speeds in a given suspension and equipment geometry was recommended, and various conclusions reported by different investigators were discussed.

悬浮液混合设备的规模放大

本文涉及用于悬浮液混合的设备的放大。在三个容器(直径分别为290 mm,600 mm和800 mm)中,使用标准的变桨四叶片涡轮和折叠四叶片涡轮进行刚刚悬浮的搅拌器速度的测量。测量结果证实,可以使用基于相对因数大小和浓度的无量纲弗劳德数依赖性的放大。根据结果​​,建议在给定的悬浮液和设备几何形状中按比例增加搅拌器速度,并讨论了不同研究者报告的各种结论。
