The Q69 series roller type shot blasting machine is a pass-through system designed for the efficient cleaning of steel plates, steel structures, and profiles. This equipment is engineered not only to remove scale and dust during the welding process but also to significantly enhance the fatigue resistance of workpieces, achieving superior surface quality.

For H-beam structures, the machine integrates high-efficient blast wheels and a full shutter type shot sand separator. The system features high-strength nylon rolling brushes and high-pressure ventilators for thorough cleaning. The entire process, including optional preheating, drying, and airless paint spraying, is synchronized and controlled via a high-performance PLC system.
