Abstract: A separator attachment for use with a vibratory apparatus, the attachment including a housing mountable to a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet. The housing has at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end. The attachment also includes a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface. The deflector plate is translatable relative to the at least one wall to vary the spacing between the deflector plate surface and the wall surface. A system including a vibratory apparatus and the attachment may also be defined.

Abstract: A vibratory crushing apparatus includes at least one trough having an inlet end, an outlet end, and a wall defining a material-receiving space having a first cross-sectional area. The apparatus also includes at least one crusher disposed in the trough, the at least one crusher having an outer surface that conforms to an inner surface of the wall about a circumference of the crusher, and a second cross-sectional area that is smaller than the first cross-sectional area so as to define a gap between the outer surface of the at least one crusher and the inner surface of the wall. Further, the apparatus includes a vibration generator coupled to the at least one trough to cause material to move between the inlet end and the outlet end and to cause the at least one crusher to move relative to the wall of the trough.
