An impeller is a rotating component used inside a shot blasting machine turbine. It plays a crucial role in controlling and accelerating abrasive media (steel shots/grits) toward the blast wheel blades for high-speed surface cleaning and finishing. The impeller ensures uniform distribution of abrasives, improves blasting efficiency, and enhances machine performance. Manufactured from high wear-resistant material, the impeller is designed for durability, consistent operation, and long service life in heavy industrial applications
