Abstract

The invention relates to a material dispersion apparatus, particularly for spreading classifiers, with an upper material supply and a material feed surface. The material feed surface is constructed as a sieve-like surface, which is installed in an air channel and the material supply is fluidized above the sieve-like surface and discharged over the outer rim of the material feed surface to fall down to the spreading classifier basket.
