ABSTRACT:
The mixing apparatus comprises an ascending pipe within a mixing container narrowing downwards like a funnel as well as an air supply pipe, concentrically provided within the ascending pipe. The ascending pipe ends in the suction space of a radial fan arranged in the lower range of the mixing container. Blast openings of the annular pressure space of the radial fan are directed to the inlet openings of the ascending pipe. The radial fan produces intensive air flow within the ascending pipe which air flow entrains the particles of the materials to be mixed.
