Abstract: A rotary drum and vibratory conveyor system including a single walled rotary drum positioned above a vibratory conveyor assembly. The rotary drum may be segmented with each segment having end flanges that are connected to an adjoining segment with bolts. A section or sections of the rotary drum have perforations covered by a dust hood that allow sand and media to fall from the drum through a funnel structure onto the conveyor assembly. The vibratory conveyor assembly includes upper and lower conveyors, where the upper conveyor collects the media falling from the drum and passes the sand to the lower conveyor. The media may be redirected back to the drum inlet to be reused.

Abstract: A conveyor may include a conveyor includes a frame, a trough supported on the frame, and a vibratory generator operatively coupled to the trough. The trough has a trough wall with a first plurality of apertures, and a plurality of baffles are spaced above the first plurality of apertures in the trough wall, the baffles defining a second plurality of apertures through which air exiting the first plurality of apertures may pass.

Abstract: A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations. The main support is equipped with a flat support temporarily attached to its first surface. All samples are loaded simultaneously. A flat surface of each sample, where the flat surfaces are a common plane, is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support using at least one cover. The flat surfaces of the samples are in predefined locations and are all in a common plane.
