Abstract: A method of separating a liquid from a liquid-laden solid material includes providing a trough having a deck defining a support surface with passages extending through the support surface. The liquid-laden solid material is deposited onto the support surface so that the liquid-laden solid material is supported by the support surface. A vibratory force is applied to the deck to separate a substantial portion of the liquid from the liquid-laden solid material. The liquid separated from the liquid-laden solid material is directed under gravity force through the passages extending through the support surface. The solid material is conveyed along the support surface by the vibratory force to a solids discharge point.

Abstract: According to the invention, a vibratory apparatus is provided having a deck resiliently mounted relative to a surface bearing the vibratory apparatus, a clamp support for a casting on the deck, and a piston freely movably mounted relative to the deck. Vibration imparting structure vibrates the deck to shake out and to loosen foreign matter adhered to the casting supported on the deck and simultaneously reciprocates and ricochets the piston relative to the deck to further shake out and loosen foreign matter on the casting. A hammer plate is provided on the deck in the path of the piston. As the vibration imparting structure is operated, the piston is intermittently forcibly driven against the hammer plate to set up a different frequency of vibration than the frequency of the primary vibratory apparatus which enhances the shake out and cleaning function of the structure.
