Machine Overview

The construction steel shot blasting machine is engineered to handle various steel profiles, including beams, pipes, and plates. It operates by propelling abrasive materials, typically steel shots or grits, at high velocities against the steel surfaces. This process not only cleans the surface but also imparts a uniform texture, improving the adhesion of subsequent coatings.

Ever dealt with the mess left behind after blasting? Our cartridge filter unit has got you covered. It separates rust, scale, and broken-down media dust, ensuring your workspace stays clean.


  • Impact Separator: This clever device keeps the filter cartridge from wearing out too quickly and acts as a spark extinguisher.
  • Automatic Cleaning: The filters are cleaned automatically with air pressure pulses, adjustable based on the dust type and amount.

6. Loading and Unloading: Smooth and Efficient

We know time is money, so our machine is designed to keep things moving swiftly. Standard roller conveyor inlets and outlets are powered by the machine’s central drive, but for extra efficiency, you can add a separate drive unit synchronized with the frequency converter.

Boost Your Efficiency:

  • Handling Bowed Workpieces: For workpieces that need extra care, a longer collection track with a reclamation conveyor ensures every bit of blast media is returned to the machine.
  • Cross-Feeding System: Integrate it into a sawmill/bore production line, and watch your efficiency soar.

7. Abrasive Blast Media: The Right Mix for the Right Job

Choosing the right blast media is like choosing the right tool for the job. For most roller conveyor setups, round blast media (cast steel shot or cut wire steel shot) is ideal. The media circulates within the machine, continuously cleaned of contaminants.

Here’s the Scoop:
Coarse Workpieces: Use a coarse abrasive media mix (steel ball shot size S390 and above).
Delicate Workpieces: Go for a fine abrasive media mix (steel ball shot size S330 and below).

8. Shot Blast Cabinet: Built to Last

Our shot blast cabinets are made entirely of manganese, known for its excellent blasting properties. This ensures durability and effectiveness, no matter how tough the job.

Durable Design:
High-Wear Areas: Extra 10mm thick manganese plates in the hot spot areas, easily replaceable.
Leak Prevention: Rubber layers in high-wear areas prevent shot leakage, mounted in a V-Track for easy replacement.

After blasting, your workpieces might still have some blast media clinging on. Our abrasive removal unit takes care of that with a rotating brush and a blow-off station using high-pressure ventilators.

Keep It Clean:

  • Rotating Brush: Interchangeable brush segments ensure thorough cleaning.
  • Adjustable Framework: Keeps the brush and screw conveyor positioned correctly for different-sized workpieces.

Cost-Effective Surface Preparation

Spending too much on maintenance and surface prep?

Who doesn’t love saving a buck? Our shot blasting machine is not only a time-saver but a money-saver too. It trims down labor costs and reduces material waste, giving your budget a much-needed breather.
