Pass-through Tunnel Blasting Machines
BlastKing is a world leader in surface preparation technology, offers a complete range of surface preparation technologies, parts and services and stands ready to improve our customers’ productivity and profitability.
The constant traveling speed of the workpieces ensures that the tunnel-type shot blasting machine can be easily and smoothly integrated into an existing production line.
The ability to adapt the moving speed of the workpiece and the wheel power ensures that the machine can be easily and smoothly integrated into an existing production line. Maximum coverage of the workpiece is achieved by the blast wheels being arranged in an “X” alignment, diagonally to the moving workpiece. In this formation, the leading edges of complex components, welded sections, and flame-cut parts can be thoroughly blasted.

Key Benefits
Tunnel Auto Blasting Machine
The workpieces are carried on rotating hooks on the Manually operated monorail or conveyed automatically on a (optional) Power & Free conveyor to the blast cabinet where they are blasted by blast wheels. The blast cycle runs in accordance with the preset blast time. When the blast wheels stop, the door is opened and the hook exits automatically.
The transport speed or index time can be coordinated to the blast wheel power and surface finish required. The system can be easily extended to suit factory layout and integrated with pre-and post-blast operations.
