Abstract
Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A container engages a support structure that includes a frame. The frame includes a dust control enclosure coupled to an outlet or a hopper at the top of the frame and the container or a discharge gate of the container. The dust control enclosure comprises a collapsible and flexible material so that a tight seal is formed between the container and the hopper or the outlet of the frame. Dust from the discharged of the bulk material from the container is contained within the support structure. A dust control panel may also be disposed at the top of the frame to prevent any dust from migrating through the frame. The container may comprise a plurality of dust enclosure panels to further prevent the escape of dust during discharge of the bulk material.
