ABSTRACT:
A bulk material receiving hopper is provided with a dust containment system which includes sloped shield plates positioned adjacent a top portion of the hopper to effectively close-off substantially all of the open space thereacross. Restricted material openings are defined by the shield plates and an isolated, dust containment region is established therebeneath to trap the displaced air and entrained fugitive dust generated during a dumping operation. One or more dust collector units communicate with the isolated dust containment region to draw in the displaced air and entrained dust particles.
