ABSTRACT:
A system (10) for delivering a cold particulate material (14) has a closed storage hopper (12) for the material, the hopper having a bottom hopper outlet (16); a venturi feeder (22) having a material inlet (20) for feeding the material, a material conduit (26) to a remote nozzle (30), and a gas inlet (24); a hopper passage (18) connecting the hopper outlet to the feeder material inlet; a gas feed valve (33), the gas feed valve being openable in response to a feed signal (40) for activating the feeder and a blast conduit to the nozzle; a heater (50) in the blast conduit for limiting cooling of a workpiece without adversely heating the material; and a comminutor (52) in the material line proximate the nozzle for delivery of the material at reduced particle size to the nozzle for increased blasting effectiveness.
