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.
