ABSTRACT:
The dust collection units in a rotary railroad car dumper installation are mounted over the hopper pit along one or both sides of the cylindrical, rotatable dumper frame so that dust ladened air can be sucked directly into the dust collection units without the need for duct work and the collected dust can be returned directly to the pit without the need for easily clogged screw conveyors and small chutes. A fixed enclosure means encloses the top and sides of the dumper frame and form with air shields mounted on the cylindrical dumper frame, a rotary valve which restricts flow such that ambient air is sucked into the hopper pit by the duct collection units at velocities which exceed the capture velocity of the dust clouds created by dumping of the contents of the car.
