ABSTRACT:
A vibratory separator for sorting solids including a housing (12) with an inlet (22) for feeding material, a first oulet (24) for discharging undersized particles, and a second oulet (26) for discharging oversized particles; and one or more screens (28) supported in the housing between the inlet and the first outlet wherein undersized particles pass through the screen and exit through the first oulet and oversized particles do not pass through the screen and exit through the second outlet; including the steps of introducing the solids into the housing via the inlet, imparting to the housing a single frequency vibration (20); and converting the single frequency vibration into a sequence of mechanical pulses applied to an interface apparatus by a multifrequency vibratory systems (48), thereby to generate a multifrequency vibration to one or more screens to cause de-agglomeration of the masses to prevent blockage of the one or more screens by particles.
