Use of Hydrocyclones for Mammalian Cell Retention ...

 · A hydrocyclone with a volume of 2.56 cm 3 was studied as a potential cell retention device for mammalian cell cultures (6 L volume). For the feasible operation range (0.9 to 1.6 L/min flow corresponding to pressure drops of 0.4 to 1.3 bar) the hydrocyclone was characterized with regard to flow split (underflow‐to‐overflow ratio) and flow ratio (underflow to supply).

Spiral classifier or hydrocyclone

A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke''s law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & Exploration Mineral ...
