Abstract

A centrifuge (10) for filtering feed material, which centrifuge comprises a conveyor (40) rotatably mounted in a rotatable housing (20), means for controlling (140) a rotational speed differential between said conveyor (40) and said rotatable housing (20), characterised in that said means for controlling (140) operate pneumatically. <IMAGE> <IMAGE>
