ABSTRACT:
An apparatus for controlling dust generated by the rotary dumping of rail cars may include one or more baffles of a rotary dump frame to seal a portion of the material receiving pit during a portion of the rotary motion. The dust cloud generated by this dumping is retained in the pit for an increased time due to tumbling of the cloud induced by the baffles and other features of the facility. A plurality of intake ducts removes the dust cloud from the pit for transfer to a remote filtering facility.
