Abstract
A blending apparatus, inexpensive in construction and requiring a minimum of recirculation, is today essential for economical and thorough blending of particulate material, for example, plastic pellets of virgin material and of pellets that have been reconstituted from recycled material. Construction of the blender is low in cost because the customary receiver, and its piping, conventionally installed below the blender are eliminated. The novel convex baffle serves:(1) as a termination surface for the conventional perforated blending conduits; and (2) retains a toroidal annular volume of particulate material in position between the upper outer surface of the baffle and the inside wall of the blender. The particulate material passes through the blending tubes, drops into the blending area below the convex baffle, whereupon the small amount of particulate material in the toroidal block or 'keystone joist' is released to proportionally blend with it.
