ABSTRACT:
A blasting apparatus for blasting a pressurized slurry against a workpiece, including an enclosed pressure vessel which is adapted to contain and hold a slurry of abrasive particles and liquid, a piping branch connected to the upper part of the pressure vessel for introducing compressed air in order to pressurize the interior of the vessel, a complementary air circuit which connect the upper part of the pressure vessel with the bottom of the vessel, the circuit having a pressure modulating device which sucks compressed air from the upper part of the vessel and delivers it to the bottom of the vessel, and a blasting gun connected for receiving pressurized slurry from the pressure vessel and discharging it against a workpiece.
