A particulate blasting apparatus includes a blast vessel having an interior for storing abrasive particulate The blast vessel has an inlet for introducing a pressurized gas into the interior of the blast vessel and an outlet for allowing the passage of the pressurized gas and particulate A flexible blast hose is coupled at one end to the outlet for directing particulate flow from the outlet and a blast nozzle is coupled to an opposite end of the blast hose A metering valve regulates different amounts of particulate flow from the blast vessel through the outlet A flow actuator is coupled to the metering valve for actuating the metering valve A controller associated with the blast nozzle in communication with the actuator controls the actuator from the blast nozzle during blasting operations. |
