System and method for blasting an overhead surface

A method of operating a blaster system comprising the steps of

• positioning said blaster system under an overhead surface, wherein said blaster system comprises
• a first enclosure comprising
• a pair of primary ports at the front surface of said first enclosure, said primary;
• and
• a pair of control cages attached at the bottom surface of said first enclosure forming a pair of curved surfaces, and a plurality of gaps, each of said curved surface comprising a slot, each end of said slot rests within each of said gaps such that said abrasive material received within said first enclosure collects within said gaps and falls into said slot;
• a second enclosure attached to said first enclosure, said second enclosure comprising
• an upper seal at the top surface of said second enclosure;
• and
• a bottom opening;
• a pair of recirculators, each of said recirculator comprising
• a hook capable of attaching said recirculators at the top opposite sides of said first enclosure;
• a neck connected below said hook, said neck comprising an outlet port facing towards inner surface of said first enclosure, said outlet port capable of releasing said collected abrasive material back to said first enclosure;
• and
• a bottom cavity at the bottom of said recirculators, said bottom cavity comprising an inlet port positionable under said bottom opening, said inlet port capable of receiving collected abrasive material from said second enclosure;
• a pair of propeller assemblies each mounted within each of said control cages, said propeller assemblies comprising
• a chamber opening positioned under said slot, said chamber opening capable of releasing said abrasive material within said second enclosure;
• a propeller placed within said second enclosure that propels said abrasive material released from said chamber opening;
• and
• a pair of electric motor assemblies capable of actuating said propeller;
• and
• loading said abrasive material into said primary port;
• turning on said blaster system to blast said overhead surface;
• receiving said waste material and said used abrasive material through said upper seal;
• receiving said used abrasive material on said inlet port positioned at the bottom of said second enclosure;
• directing said used abrasive material to said outlet port positioned at the opposite top side of said first enclosure through said loader valves on each of said recirculators;
• and
• reloading said used abrasive material on said slot.
