Abstract
A cyclone separator (10) of the dewatering type which comprises an elongated separating chamber (12) having an axis of symmetry between opposite first and second ends, the separating chamber being of greater cross-sectional dimension at the first end than at the second end. The cyclone separator further includes at least one inlet (20) which is adjacent the first end and at least one overflow outlet (25) for the less dense component and at least one underflow outlet (24) for the more dense component (24). The cyclone separator has a first section (14) which contains the feed inlet (20) and the first section is of reduced cross-sectional dimension d.sub.2 at its downstream end relative to the upstream end and is characterized in that the ratio of cross-sectional dimension of the overflow outlet for the less dense component d.sub.0 to the cross-sectional dimension of the first section at its downstream end d.sub.2 is as follows 0.25<D.sub.0 /d.sub.2 0.65.
