A vortex zone (A) is nozzle loading zone (B), a mixing zone (C) and a outlet hose (16) are used. They all form part of an outlet section (2) containing the outlet nozzle and connected to the central pipe-line (1) carrying the material. The vortex zone consists of a pipe section fitted with guide vanes (4) arranged in a spiral pattern. The material is pneumatically conveyed along the pipe (1).
