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.

Abstract: An integrated vibratory adapter device for providing multi-frequency oscillation of a vibratable working unit, includes a working member associated with the working unit so as to be in force transmissive relation therewith; centrifugal vibratory apparatus for generating a single frequency sinusoidal vibration; rigid impact apparatus arranged to receive a single frequency sinusoidal vibration from the vibratory apparatus; resilient mounting apparatus for mounting the rigid impact apparatus in motion transmitting association with the working member and which is operative, when the vibratory apparatus is operated, so as to vibrate the rigid impact apparatus such that it transmits vibration forces to the working member; and one or more elastic buffers spaced between the rigid impact apparatus and the working member such that, when the vibratory apparatus is operated, the rigid impact apparatus elastically strikes the working member through the one or more elastic buffers such that the rigid impact apparatus trans
