APPARATUS AND METHOD FOR INCREASING DENSITY OF FINELY DIVIDED PARTICULATE MATTER

摘要

An apparatus for removing air from finely divided particulate material comprises a housing including a vent; an inlet to the housing; an outlet from the housing; a helix, rotatably mounted in the housing, the helix being adapted upon rotation to feed a particulate material from the inlet to the outlet; a motor mounted to the helix for the purpose of rotating the helix; and a compression assembly mounted to the outlet for compressing the particulate material passing through the outlet.
