Abstract
A decanting type centrifuge having a main bowl which is adapted to be rotated about its longitudinal axis and which contains a helical scroll conveyor which is arranged to rotate about the main bowl axis at a slightly different speed to the main bowl for scrolling separated solids to a solids discharge end of the bowl. The centrifuge includes a means which acts to isolate a gas volume radially inwardly of the inner liquid surface within the bowl and also a passage arrangement which enables gas to be extracted continuously from the isolated gas volume to a location external to the main bowl.
