Patent ID: 7052362

Claim:
A blasting media system comprising at least first and second types of different blasting particles, the system comprising: a) a first container containing a supply of at least the first type of blasting particles; b) a first supply conduit having a first end and a second end, the second end facilitating discharge of at least the first type of blasting particles against a surface to be treated for providing a desired surface treatment thereof; c) a first metering device for metering at least the first type of blasting particles from the container into the first end of the supply conduit; and d) a first device for pressurizing the first end of the supply conduit with a pressurized fluid whereby the pressurized fluid and at least the first type of blasting particles mix with one another in the supply conduit to form a pressurized mixture thereof; wherein the second type of blasting particles is mixed with the first type of blasting particles and the pressurized fluid, prior to the first and the second types of particles contacting the surface to be treated, whereby the first and second mixed particles comprise two separate types of blasting particles which facilitates the desired surface treatment of the surface to be treated and reuse of the first and the second types of particles; a blasting nozzle is secured to the second end of the supply conduit for directing the mixed first and second types of particles against the surface to be cleaned; and the second type of blasting particles is mixed with the first type of blasting particles in the first container and supplied together into the supply conduit by the first metering device.
