A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving a more efficient mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. The system supports dry blasting, wet blasting, and water wash down modes and air drying modes. When blasting, by more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The water injectors are downstream of the air/abrasive mixing station.
A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving better application of the mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. By more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The abrasive flow is shaped as it is released from the metering valve in order to tighten the abrasive flow before it enters into the blast air stream. The shaped and tightened abrasive flow is maintained at the lower portion of the blast air stream. This positions the abrasive flow in optimum placement for spray wetting the abrasive as it flows into and through the nozzle. This also mitigates nozzle clogging by directing most of the abrasive flow away from the water spray nozzle port.
