Apparatus and method for uniformly spreading a flowing stream of dry solids, which may include solid particles and lumps of varying sizes, with minimal segregation, which utilizes an adjustable dam having a curved crest for forming in the flowing stream a mass of solids in the shape of a segment of a cone, over the surface of which the stream is spread from a relatively narrow stream at the apex of the cone to a relatively wide stream at the base of the cone, and including a mechanism for adjusting the dam to vary the degree of transverse arc curvature of the spreading surface. As an alternative, the spreading surface may be formed by a series of elongated, adjustable bars.
