Abstract
An integrated dust containment system for machines such as rotary crusher/breakers, vibratory screens and the like of the type use in sizing dusty bulk materials, such as for coal, ore and the like. A substantially airtight enclosure having integral air filter means and fan means is detachably fitted to the machine housing adjacent the material treating station such that the air filter means is in communication with the dust generation area of the machine. A negative draft generated by the fan means draws in dust laden air from inlet and discharge zones of the machine, as well as from the material treating station for capture of the dust in the filter means and susequent discharge of clean, filtered air from the fan means. Pulsed, compressed air back flushing of the filter means cleans the filters and returns the collected dust cake to the machine interior for subsequent recovery.
