ABSTRACT:
Improved powder compacting apparatus for feeding powder between rollers to form a compressed material with enhanced physical properties including uniformity to facilitate forming tablets and similar items therefrom. Side seals confine the powder between the rollers and can be movable independently from the rollers and optionally independently from one another to enhance even compaction. A housing defines a guide channel with a linear feed and shearing zone immediately prior to the nip zone for smoothing and leveling powder flow. One or more vents are provided for releasing gases generated.
