Abstract
This invention is about a cyclone separator, and may be applied to the cyclone separators disclosed and claimed in UK Pat. Nos. 1583742, 1583730 or 2102311, or those described in UK Patent Application 8419771 or 8511149 or 8515264. Thus, application 8419771 describes a cyclone separator which has an inlet portion having generally the form of a volume of revolution with a single tangential inlet (preferably with an involute feed channel, for introducing feed to be separated into the cyclone separator and, adjacent to the inlet portion and substantially coaxial therewith, a generally axially symmetrical separation portion converging uninterruptedly into a downstream portion. The inlet portion has an axial overflow outlet opposite the separation portion (i.e. in its end wall). The involute feed channell may be fed from a duct directed tangentially into the inlet portion, the (outer) wall of the channel converging to the principal diameter of the inlet portion, preferably by substantially equal radial decrements per unit angle around the axis, preferably attaining the principal diameter after 360.degree. around the axis.
