Abstract
A centrifugal solids-liquids separator comprises a rotatable hollow centrifuge drum at least a part of which is tapered, and which is rotatable about its axis, means for introducing a slurry of solids and liquids to be separated at a point along the length of the drum spaced from a wider end so that rotation of the drum tends to cause migration of the slurry towards the said wider end, and scraper conveyor means rotatable about an axis coincident with that of the drum and at a relative speed which is low in relation to the absolute speed of the drum, the scraper conveyor means being so mounted that they act in direct contact with the inside surface of the drum so as to displace solids contacted thereby towards the narrow end of the drum against the axial force induced by the rotation.
