Abstract

A centrifugal method for fractionating fine (<10 μm) particles by size and/or density is described. Periodic, bidirectional flow through a continuously spinning coiled tube splits fine particle suspensions into two fractions. Proof-of-principle experiments with zeolite powder have demonstrated successful concentration of aqueous dispersions.
