A material handling transfer system which utilizes passive dust control methods for containing and controlling fugitive dust emissions generated during a transfer operation. The present system includes an enclosure containment structure which houses a specialty designed transfer chute for vectoring a stream of moving material from a first elevated transfer location to a second lower transfer location, the chute being constructed to reduce fugitive dust emissions at the second transfer location, an adjustable deflector mechanism for containing and funneling the bulk material onto the transfer chute structure, and a stilling zone positioned downstream from the second transfer location for impeding the propagation of any fugitive dust emissions through the exit area of the enclosure structure. The present enclosure structure is specifically designed to allow for recirculation of the induced air flow generated within the enclosure structure to both relieve any pressure build up formed therewithin, particularly, in the vicinity of the second transfer location, and to facilitate the agglomeration of dust particles within the enclosure. The present system is adaptable for use in a wide variety of different material handling transfer applications including applications which involve a belt-to-belt transfer operation, a belt-to-bin transfer operation, a bin-to-belt transfer operation, a crusher-to-belt transfer operation, and both in-line and angular transfer operations. The present system therefore provides a more cost effective and less complicated system for achieving a safe work environment in areas where fugitive dust emissions must be controlled and contained.
