Steel Frame Hook Type Shot Blasting Machine for Surface Treatment

Why a hook-type layout for steel frames

Steel building frames, welded assemblies and heavy castings are awkward to tumble or belt-convey. A hook-type (spinner-hanger) machine suspends each part on a motorized hook that rotates inside the blast chamber, so the workpiece hangs free and gets blasted from every angle. Thin-walled sections and large frames are cleaned without deformation or handling marks.

What the machine delivers

• Rotating hook carrier — every part spins on its own axis during the cycle, exposing all faces to the blast wheels.
• High-efficiency blast wheels — positioned to throw abrasive at the angles that matter for structural steel and castings.
• Integrated abrasive recovery — screw conveyor, bucket elevator and separator return clean steel shot to the wheels continuously.
• Dust collection — a cartridge or bag filter keeps the chamber and the workshop within emission limits.
• PLC control — automatic cycle with adjustable blast time and part indexing (control components selected per project).

Results and where it fits

After a single batch cycle the surface reaches the cleanliness needed for painting, coating or welding, with a uniform anchor profile. It suits steel building frames, bridge structures, boiler parts and heavy castings. Very small parts or very high-volume identical pieces are better served by tumble or mesh-belt lines.
