Zusammenfassung:	A screening means (10) for a suspension of at least two types of particles dispersed in a fluid comprising at least one substantially cylindrical screen (12), supported on a frame (11), adapted to rotate about a substantially vertical axis. Each screen (12) is adapted to allow particles of dimensions less than a certain dimension to pass through the screen (12) and so be separated from those particles that are greater than the certain dimensions which are retained within the screen (12). Those particles retained within the screen (12) can be dislodged and recovered through use of a jet of fluid from nozzle (26) directed against the outer surface of the screen (12) which washes the particles into a launder (27) where they are collected.
