Mixing in shaker table beakers is studied using dye dispersion to measure mixing times. Experimental conditions range from the laminar regime into the turbulent mixing. Different flow patterns occurring in the beakers are reported for the mixing. The transition Reynolds number is determined. Rotational speed of the table, volume of material to be mixed, and viscosity of the material are studied as to their effects on mixing time. A graphical mixing time correlation is provided which is useful for the translation of mixing from laboratory scale to pilot scale.
在摇床烧杯中混合使用染料分散来测量混合时间。实验条件从层流范围扩展到了湍流混合。报道了在混合过程中在烧杯中发生的不同流动模式。确定了过渡雷诺数。研究了摇床的转速、要混合的物料体积和物料的粘度对混合时间的影响。提供了一个有用的图形混合时间关联，可用于将实验室规模的混合转化为中试规模。
