System and method for forming a compressed substrate having a generally uniform density from powders

Abstract

A system and method for processing powdered materials. The system has a first roller, a second roller, and a compression zone for compressing the powdered material between the rollers. At least one oscillating guide plate is provided that has a curved edge that face the first roller. A curved channel is formed between the curved edge and the first roller. The curved channel tapers from a wide entrance opening to a narrower exit opening. The exit opening leads into the compression zone between the rollers. The curved channel receives the powdered material and compresses the powdered material as the powdered material advances. However, due to the curvature of the curved channel, the powdered material is sheared as it is transitioned and redistributed to the narrower cross section while gaining uniformity of flow and density. The result is that a compressed powdered material with generally uniform density.
