Strata High Pressure Bulk Dusters

High pressure bulk dusters distribute high volumes of rock dust over large areas very rapidly. These units are ideal for main entries and roadways, and can be used for dusting return entries and belt line entries with longer hoses.

Rail or rubber tire-mounted, these large capacity dusters are pulled by locomotives and can be operated by as few as one or two individuals. Rock dust is applied by hose. 

Models include single or double onboard storage PODs (round) or tanks (cylinders), with capacities ranging from 1.5 to 12 tons – (1.36 to 10.8 tonnes) of rock dust. They are filled mechanically, either directly at the storage bin on the surface, or via a borehole underground. Bulk dusters can function as underground storage to supply smaller mobile rock dusters.

The Rail Master High Pressure Duster is a self-contained rock duster with motor and compressor. The Rail Slave duster does not include a motor or compressor, but instead is coupled with the Rail Master for additional storage and fast access to rock dust supplies. It can also be attached to mine air to be pressurized for independent function in a specific location.
