<p>Apparatus (20) for separating drilled solids from drilling mud comprising a centrifuge having a hollow axially extending member (22) mounted for rotation about its axis. The member (20) has a permeable peripheral wall (24). A drilling mixture of mud and drilled solids is introduced into the interior of the member (20). The member (20) is rotated by a drive motor (60) at a speed sufficient to effect separation of the mud and drilled solids such that under centrifugal action at least some of the mud passes through the permeable peripheral wall and at least some of the drilled solids are retained in the interior of the member (20). The apparatus is arranged for removal of the separated drilled solids from the interior of the member (22).</p> |
