ABSTRACT:
An apparatus for handling a mixture of dry particulate materials, such as a fertilizer, is disclosed, which is able to substantially alleviate the problem of particle segregation which normally results from the handling of such mixtures. The apparatus comprises a circular grate which is composed of a plurality of concentric annular rings defining annular openings therebetween. The grate is mounted for rotation about a vertical axis, and in use, the fertilizer is delivered onto the upper surface of the grate while the grate is rotated. The fertilizer falls through the openings without substantial segregation, to form a large circular discharge pattern which in turn forms a non-segregated relatively flat pile in an underlying truckbed or the like.
