SCHUMANN, W. A.. Large Separation Factors in Short Bowl Centrifuges. R&D j. (Matieland, Online) [online]. 1988, vol.4, pp.14-24. ISSN 2309-8988.

The possibility of obtaining large separation factors in short bowl centrifuges is discussed in this report. A suitably modified internal configuration, e.g. employment of an internal single start spiral, could enforce a desired counter current flow pattern over a long active separating length, thus creating conditions for large separation factors in a short centrifuge. Desired flow patterns are assumed and a simplified model used to indicate the influence and sensitivity of various geometrical and flow parameters on centrifuge performance in a parametric study. A comparison is made between separating characteristics of a conventional and a spiral centrifuge operated under similar conditions.
