ABSTRACT:
A vibratory material conveying apparatus has a tower with a spiral flight to be vibrated for conveying material vertically, a platform through which the tower extends, structure for resiliently supporting the platform above a support surface for the apparatus, structure for resiliently attaching the spiral flight to the platform, and structure for imparting vibration to the platform. The invention comprehends a two mass system with the platform and vibration imparting structure, a force member mass and a work member mass. The system permits large amplitude vibrations to be imparted to the work member with minimal dynamic reaction to the support surface from the force member vibration.
