ABSTRACT OF THE DISCLOSURE The invention relates to vibratory material handling apparatus and more particularly to a dual exciter system drive for vibrating the apparatus wherein the exciters are positioned on either side of the center of gravity of the apparatus and direct vibrations at obtuse and acute angles, respectively, through the center of gravity of the apparatus, the arrangement being such whereby the vibratory force exerted by each exciter may selectively be varied so as to cause the apparatus to vibrate vertically, or displaced from the vertical, so as to convey in one direction or the opposite direction. The arrangement is such that the spring system connecting the exciters to the material-handling apparatus acts as isolation springs when the vibration generator associated therewith is inoperative, and as tuned natural frequency systems when the vibrator is actuating. The invention also provides a shakeout screen and sand lump breaking apparatus combined into a single unit, thereby providing an apparatus particularly useful in removing foundry sand from castings and breaking down lumps in the sand to permit the reuse thereof.
