Roller Conveyor Shot Blasting Machine Q69 | Jinwo, Qingdao, China

Jinwo's Roller Conveyor Shot Blasting Machine Q69 is a fully automatic, continuous blasting line that cleans and strengthens steel structural components. It removes rust, mill scale and welding slag from H-beams, I-beams, channels, steel plates and box girders.

Workpieces travel through the blasting chamber on a roller conveyor at a constant, adjustable speed while several blast wheels throw steel shot at them from different angles. The machine is customisable and is offered in a range of cleaning widths and blasting capacities.

Key Features

• Roller conveyor with adjustable speed carries heavy and extra-long workpieces through the chamber
• Multiple cantilever centrifugal blast wheels hit the workpiece from different angles
• High-chromium steel protective plates line the cleaning chamber for wear and impact resistance
• Shot is recovered by screw conveyors, bucket elevators and separators, then reused
• Pulse cartridge dust removal system
• PLC and touch screen control with automatic and manual modes
• Modular design; can reach a Sa2.5–Sa3 derusting grade
