Abstract
A centrifuge drum is provided with a seal consisting of a narrow gap between the drum and centrifuge housing. The seal is located between the actual housing and the solids catch chamber. There is a pressure-compensation space at the drum in the vicinity of the seal. The exchange of air that occurs at the seal in a centrifuge without the compensation space between the solids catch chamber and the housing in accordance with the invention and that leads to deposits of solids in the housing is accordingly displaced into the compensation space.
