Abstract: A vibratory conveying apparatus is provided with an improved V-shaped trough which conveys material up an inclined path. The angled walls of the trough enhance the frictional forces between the particles of material which, when combined with the frictional forces between the walls and the material, increases the ability of the material to be efficiently conveyed up an inclined path. The trough has a surface with a high coefficient of friction which aids in the conveying action. The higher coefficient of friction may be obtained by the type of material used for the surface of the trough or may be obtained by providing corrugating, ribbing or the like on the surface. The conveying action with the V-shaped trough also abraids the material so as to clean and process the material.

Abstract: A resilient liner is provided on the particle supporting surface(s) of a vibratory conveyor system. The liner accounts for a live surface that counters the tendency of the particles, particularly those that are moist and sticky, from adhering to each other and the conveying surface. The liner is particularly effective in systems such as separating systems wherein the particles at various stages fall to other levels.
