ABSTRACT:
This invention relates to an improved particulate receiving chamber within a centrifugal separation device and more particularly within a decanter centrifuge. The improved receiving chamber reduces particle disintegration of the particulates which is particularly advantageous if the particulates are subjected to a further centrifugal separation step because particle disintegration compromises the clarification achievable by successive centrifugal separators. The preferred embodiment of the particulate receiving chamber includes a plurality of spray nozzles for spraying fluid in the chamber whereby the fluid absorbs the impact forces of the particulates which impact against surfaces within the chamber.
