(57) An apparatus for processing particulates comprises a vibratory bed including a motor
(20) with a vertically disposed shaft (22), at least one eccentric weight (26) disposed
on the shaft, a housing (32) secured to and enclosing the motor. A bed plate (40)
is secured atop the housing whereby operation of the motor (20) imparts vibrational
gyratory motion to he housing and the bed plate. When vibrational gyratory motion
of the bed plate has an acceleration in excess of gravity, the bed plate (40) will
impact a vessel (60) on the bed plate at multiple frequencies for each revolution
of the shaft. The impacts at the multiple frequencies will fluidize the particulates
so that they can flow into cavities and crevices in a pattern or the like.
