Abstract
A centrifuge drum for concentrating suspended solids, which are conveyed through channels out of an outer solids space in the drum and into a radially inner peeling chamber, whence they are diverted by a peeler and by an associated concentrate line. A separated clear phase is continuously extracted from the interior of the drum by another peeler and by an associated clear-phase line. The object is to prevent the concentrated solids from heating up undesirably even when their volume is small. There is an opening-and-closing communicating line between the concentrate line and the clear-phase line and an opening-and-closing recirculation line extending into the first peeling chamber from the clear-phase line. The communicating line and the recirculation line are closed to divert the solids and opened to discontinue the diversion.
