  • Patent number: 9278428
    Abstract: An apparatus for reclaiming abrasive blasting material comprises a prime mover, a vacuum pump and a separator unit for separating the abrasive blasting material in the contaminated abrasive blasting material from contaminants. The vacuum pick-up draws the contaminated abrasive blasting material. The separator unit includes a screening device for separating and reclaiming the abrasive blasting material. The screening device comprises a support member having a longitudinal axis and a transverse axis, and an endless flexible screen belt mounted to the support member so as to be movable along an endless closed loop in the direction of the longitudinal axis. The screen belt has a plurality of openings being sized to allow particles of the abrasive blasting material of a desired size to fall therethrough by gravity and to prevent the contaminants larger than the abrasive blasting material from falling therethrough.

    Abstract: A belt conveyor for conveying granular material comprises a tube and a hopper. Guide members guide the belt from a flat orientation as the belt leaves the lower roller into a cupped orientation as the belt enters the hopper. The cupped orientation is maintained by sliding contact at an interface between the lower surface of the belt and the hopper walls as the belt passes through the hopper. Left and right baffle members are attached along the hopper side walls and thereby prevent the granular material from sliding down the hopper walls into contact with the interface between the lower surface of the belt and the hopper walls. The belt has a width that is substantially fully exposed to granular material entering the hopper. A method of increasing the capacity of a belt conveyor comprises reducing the width of the flashing covering belt side portions.
