Abstract

Installation for the transformation of liquid phases of non-metallic substances, especially polymerizable or crystallizable, into a solid phase, with a reaction chamber in the form of a tubular hollow body held vertically, at whose upper end the liquid phase is adduced and at the lower end of which the solid phase is continuously evacuated, characterized in that the reaction chamber (1) is surrounded, at least in the upper area containing the liquid phase, by an envelope (5) of polygonal cross section, where each of the wall sections of the correspondingly polygonal cross-section chamber is made up of a branch (2), which is applied to the corresponding section of the envelope, of an endless belt (4), which with its indicated branch (2) moves continuously downward, being synchronously driven with each of the remaining belts.
