Abstract
A multi-start spiral separator for separating particles in a stream of such particles according to their respective densities and/or sizes comprises a plurality of substantially helical troughs arranged around a common axis which is substantially vertical, each trough including at an upper end an upwardly-facing open fluid-receiving portion and at a lower end an outlet, and a fluid delivery pipe which delivers fluid to the spiral separator so that fluid is distributed to the receiving portions of the helical troughs uniformly.
