2-wheel shot blasting machine YG series

single-discfor surface cleaningfor concrete

Overview
A mobile shot blasting machine for cleaning and profiling horizontal surfaces such as concrete, asphalt and steel decks. Designed to operate as a closed-loop system with integrated shot recovery and dust collection to reduce airborne dust and recycle abrasive shot.

How it works
The centrifugal blast wheel projects steel shot onto the surface to remove contaminants, old coatings and laitance, producing a specified Concrete Surface Profile (CSP). An integrated dust collector and separator recover reusable shot and capture fines to minimize waste and maintain site cleanliness. Optional HEPA-class filtration is available for stricter indoor air requirements.

Top benefits

• Dry process: No water required; coatings can typically be applied immediately after blasting.
• Consistent texture: Produces uniform surface profile for optimal adhesion of epoxy and waterproofing membranes.
• Recycling: Recovers and reuses steel shot, reducing consumable costs.
• Dust control: Integrated dust collection and separation reduce airborne particles and improve workplace safety.
• Versatility: Effective on concrete, asphalt and steel decks (including ship decks).

Typical applications

• Highway and bridge deck preparation for overlays and maintenance.
• Airport runway rubber removal and macro-texture restoration.
• Industrial and warehouse floor preparation prior to epoxy or polymer coatings.

Case study results (example)

• Efficiency: field reports up to 600 m2/h on larger models.
• Labor savings: significant reductions compared to manual surface preparation methods.
• Quality: consistent CSP values suitable for polymer and cementitious overlays.
