The Tunnel Type Airless Shot Blasting Machine is a continuous, high-production roller conveyor shot blasting machine designed for cleaning long or flat components such as plates, fabricated structures, pipes, beams, channels, and sections. It is engineered for uninterrupted production where components require efficient surface preparation in a single pass.
Components move through a blasting chamber or tunnel on a conveyor system while multiple high-speed blast wheel units project abrasive media from optimized angles. This ensures uniform cleaning, rust removal, descaling, and coating preparation with high productivity.
Available ConfigurationsFor sheet, plate, and other flat components that have a length
Smart Process Overview
Components are loaded onto the inlet conveyor and moved into the blasting chamber. Inside the tunnel, multiple shot blasting turbine units positioned at calculated angles project abrasive media at high velocity onto the component surfaces.
Continuous conveyor movement exposes the entire surface to the abrasive stream for complete cleaning. For pipe applications, diabolo rollers rotate the job during blasting to ensure full circumferential coverage.
Used abrasive falls into the hopper and is recovered through the screw conveyor, bucket elevator, and air wash separator. Clean abrasive is reused, while dust and fine particles are extracted through the integrated dust collector system. Cleaned components exit through the outlet conveyor ready for painting, coating, or further processing.
