The workpiece is continuously rotated and blasted to remove rust, scale, paint, and other contaminants. Spinner hanger shot blasting machines are commonly used in industries like automotive, foundries, and metal fabrication. They offer effective and efficient surface cleaning and preparation, ensuring optimal adhesion for coatings or further processing.
