Vibratory tube feeder for powder transfer system.

摘要

Apparatus for controlling the flow of powder to a point of use in a powder processing system. The apparatus includes a first hopper (16) vibrated at a predetermined frequency to help assure that the powder is discharged as required onto a horizontal feeder tube (32) which also has vibrators (40) for transferring powder along the horizontal feeder tube (32). The horizontal feeder tube (32) extends into a second hopper (44) which then channels tha powder to a point of use, such as a roll compactor. A level sensor (33 or 56) equipped with a probe (35 or 55) determines powder height and acts to control operation of the vibrators (40) which move powder through the system.
