  • Foam Configured to Suppress Dust on a Surface to be Worked
    Publication number: 20120279003
    Abstract: In one aspect of the invention, a system for removing aggregate from a natural or man-made surface includes a vehicle with a frame and a conveyor. The conveyor has an intake end and an output end. An excavation drum is connected to an underside of the frame and is enclosed within an excavation chamber, which is defined by a front plate, side plates, and a moldboard. The intake end of the conveyor that protrudes into the excavation chamber is configured to remove the aggregate from the excavation chamber, and a dust suppressant nozzle is configured to apply a foamed dust suppressant to the natural or man-made surface prior to being degraded by the excavation drum.
