Abstract
Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A support structure may include a plurality of outlets or chutes for discharging the bulk material. A dust control damper coupled to the outlets not currently in use for the discharge of bulk material may prevent dust from escaping into the surrounding air. The dust control dampers may automatically transition between a closed position and an open position. A flexibly collapsible shroud may also be coupled to a discharge gate of a container. The shroud may expand to seal against the outlet when bulk material is discharge. A vacuum system at or near an outlet may reclaim any dust that escapes during discharge of the bulk material.
