Bantam High Pressure Rock Dust Distributors
This type of rock dust distributor can be used on shuttle car, conveyor or track sections where proper height does not afford a track mine type.  With 50 ft. of hose, it is possible to completely dust the entire section.

Track Mounted Rock Dust Distributor
It is an established fact that rock dusting in coal mines, if properly distributed and in amounts great enough to render the coal dust 65% noncombustible, will eliminate all dust explosions and localize all gas explosions.   Rock dust should be distributed in every entry, air course room, pillar and along pillar falls.  In rooms and entrys that have been stopped, the dusting should extend to the face.  In actual works rock dusting should extend at least to within 100 feet of the face.  It is desirable that supplies of rock dust be left on each live working section, so that it may be distributed from time to time as the face advances, in addition to the rock dust distributed periodically by rock dusting machines and rock dusting crews.
