Abstract

The invention relates to an improved acceleration nozzle for gas-solids and a counterjet pulverizer as well as a pulverizing and a classification part for such an acceleration nozzle. The acceleration nozzle is therefore known that in the outlet end of a conventional acceleration nozzle (1) a tubular head (2) is arranged, the flow channel (3) of which is either throughout of the same size or at least as to its end portion tapering the flow direction and in the wall of the head from the direction of the flow channel (3) middle axis (A) several diagonally outwards reaching gas outlet channels (4) are made.
