The shot blasting room, also known as the abrasive blasting room or sandblasting room, is suitable for surface cleaning and rust removal on large workpieces, enhancing the adhesion between the workpiece and the coating. Before the shot blasting operation, place the workpiece in the blasting chamber, connect the electrical and gas systems, turn on the blasting lighting, wear protective gear, close the main unit door, hold the blasting gun, turn on the blasting switch, and blast clean the parts with the gun. The steel shots ejected fall to the bottom collection area of the blasting room and are recycled by a spiral feed conveyor into a hoist. They pass through a cyclone separator to separate the shots, broken steel shots, and dust. Qualified steel shots are then transferred directly into the storage bin above the blasting unit for reuse. The broken steel shots and dust are directly vacuumed away by the dust removal system, adhering to the filter sleeve surface. The dust collector's pulse valve generates timed pulse signals, releasing compressed air from the air tank to form an expanding air flow that acts on the inside of the filter sleeve, causing the dust adhered to the surface to vibrate off and fall into the lower dust collection bin, which is cleaned regularly.
