VIELACHSIGE EINRICHTUNG FUER DIE HERSTELLUNG VON PARTIKELN UND DERGLEICHEN(.

摘要

An apparatus for processing particulates comprises a vibratory bed including a motor (20) with a vertically disposed shaft (22), separate remote adjustable vibratory generating apparatus mounted on each end portion of the shaft and at least three contact structures (165) between the vibratory bed (40) and a flask or vessel (60) containing the particulates. The uppermost vibratory generating apparatus are remotely adjustable to vary the horizontal vibratory force component and the lowermost vibratory generating apparatus are remotely adjustable to vary the vertical conical force component. The contact structures (165) have conically shaped mating surfaces on pins (166) and in recesses in sockets (168) such that when at least one of the conically shaped surfaces are in contact the vessel is restrained to the same horizontal movement as the bed plate. When vibrational gyratory motion of the bed plate has an acceleration in excess of gravity, the bed plate will impact the vessel with a vertical component progressively from one contact structure to the next at multiple frequencies for each revolution of the shaft. The impacts at the multiple frequencies will fluidize the particulates so that the particulates will flow into cavities and crevices in a pattern or the like in the vessel.
