Particulate solids are separated from their admixture with gases by passage through a cyclone separator, wherein the solids are guided down the lower conical section thereof by helical channels which minimize recirculation of the particles and thereby minimize agglomeration thereof.

A cyclone separator for the separation of gases from polymer particles including an upper barrel, a gas outlet, a lower barrel, and a truncated cone below said lower barrel wherein: a. at least one jet inlet is positioned to the upper part of the upper barrel for introducing particulate solids-laden gases tangentially into the barrel; b. the upper barrel is positioned on the top end of the lower barrel; c. the gas outlet is of smaller diameter and concentric with the upper barrel and extends into the upper part of the lower barrel; d. the bottom end of the lower barrel being positioned on the widest face of the truncated cone; e. said cone being fitted with at least one helical channel along the inner face of the cone leading to the outlet, said outlet comprising the smaller face of the truncated cone; f. and an essentially vertical transition strip positioned to have one end thereof supported by the cone and the opposite end thereof supported by the channel.
