A device for eliminating fugitive material dust emanating from material being transferred from an upper conveyor, feeder or crusher to a lower position, or other location. The device allows adjustability of the chute's total flow capacity where increased capacity is required. The device has a sliding gate disposed in the hopper to control the rate of transfer of the material from the hopper. A chute is disposed below the hopper and is movable in both a lateral direction (transverse to the direction of belt travel), and movable in the axis of belt travel. A choke is slidably attached to the chute, and slidable therein. The gate is positioned to maintain a level of material in the hopper to prevent dust from emanating out of the hopper from the chute. The choke is positioned to reduce airflow through the material as it passes through the chute to a lower position.
