YG Machinery

A floor shot blaster is a mechanical surface-preparation machine that uses a high-speed rotating wheel to project steel abrasive against concrete, steel, or other suitable surfaces. The impact removes laitance, weak surface material, old coatings, and contaminants, while simultaneously creating a textured profile that can improve the adhesion of subsequent coatings, overlays, or waterproofing membranes.
For contractors working on concrete floors, bridge decks, airport runways, parking structures, industrial warehouses, or road surfaces, a floor shot blasting machine can offer an efficient alternative to grinding, scarifying, or manual preparation — provided the equipment is matched to the substrate, the coating type, the project area, and the available power supply.
YG Machinery manufactures floor shot blasters in three models, with working widths from 270 mm to 800 mm, in single-motor and double-motor configurations. All models feature self-propelled travel and are designed for use with an automatic backflush dust collector.
Before selecting a floor shot blaster, buyers should confirm the substrate, surface condition, coating type, required profile, working width, power supply, and dust-collection requirements.

9 Key Features of the YG Hot-sale Concrete Shot Blasting Machine

1. Controlled Shot Blasting

The machine uses a centrifugal shot wheel to project steel abrasive at a controlled speed and angle. This approach:

• Supports consistent surface treatment across open areas.
• Can remove laitance, weak surface material, and selected coatings.
• Creates a mechanical profile that may improve coating or overlay adhesion.

The actual result depends on abrasive size, travel speed, substrate hardness, coating type and the number of passes. Not every coating can be removed in a single pass.

2. Available Working Width Options

YG offers three working widths to match different project scales:

• YG-270: 270 mm — suitable for smaller areas, edges, and confined spaces.
• YG550/600: 550/600 mm — a mid-range option for parking lots, warehouses, and road sections.
• YG-850: 800 mm — designed for large-area projects such as industrial floors and airport surfaces.

A wider working width may improve productivity on open areas but may be less practical in tight corners or around obstacles.

3. Abrasive Recovery and Recycling

The machine features a closed-loop recovery system:

• Collects reusable steel shot after impact.
• Separates removed debris and dust.
• Returns clean shot to the hopper for reuse.
• Average steel shot consumption is approximately 10 g/m² (varies by surface condition).

Recovery efficiency depends on dust collector performance, separator condition and abrasive quality.

4. Dust-Collection System

YG floor shot blasters are paired with automatic backflush dust collectors:

• YG-270: Seven-core automatic backflush vacuum cleaner.
• YG550/600 and YG-850: Eight-core automatic backflush vacuum cleaners.

The dust collector:

• Helps control airborne dust at the work site.
• Provides the airflow necessary for abrasive separation.
• The backflush function cleans filters during operation.

The dust collector is essential for proper machine operation — without adequate airflow, separation efficiency drops and dust accumulates inside the blasting chamber.

5. Self-Propelled Travel

All YG models feature self-propelled travel with adjustable speed:

• YG-270: Walking speed 0.5–20 m/min.
• YG550/600: Walking speed 0.5–33 m/min.

Self-propelled travel can reduce operator fatigue and help maintain more consistent pass overlap on large areas.

6. Compact Design

The machines are designed to be maneuverable:

• YG-270: 1000×300×1100 mm, 150 kg — can pass through standard doorways.
• YG550/600: 1950×720×1400 mm, 570 kg.
• YG-850: 1950×1020×1550 mm, 700 kg.

Compact dimensions help on indoor floors, parking decks and bridge surfaces, but the machine still requires adequate access for operation and dust-collector placement.

7. Durable Shot Wheel and Wear Parts

Key wear parts include:

• Shot wheel blades — inspect every 50–100 working hours; replace as a full set when grooves appear or thickness is significantly reduced.
• Control cage and impeller — inspect together with blades.
• Top and side liners — protect the blasting chamber; replace when thinning or cracking is found.

8. Maintenance Requirements

Regular maintenance includes:

• Shot wheel and blade inspection.
• Abrasive separator cleaning.
• Dust hose and filter inspection.
• Seal and liner inspection.
• Motor and drive-system check.
• Electrical connection check.

This machine is not maintenance-free. Regular inspection of wear parts is essential for consistent performance.

9. Surface-Profile Control

The surface result may be influenced by:

• Abrasive size and hardness.
• Travel speed.
• Number of passes.
• Surface hardness and condition.
• Coating type and thickness.
• Machine settings.

Without test data for a specific surface, it is not possible to guarantee a specific roughness value or coating-removal result. A test area is recommended.

Suitable for:

• Warehouses and logistics centers.
• Factories and workshops.
• Parking structures and commercial garages.
• Food-processing and pharmaceutical facilities (subject to hygiene requirements).

Common tasks include removing oil stains, old coatings, laitance, and preparing floors for new epoxy or polyurethane systems.

6. Steel Surface Preparation

The machine can treat steel plates for:

• Rust removal.
• Old paint removal.
• Surface profiling before coating.

Applications Requiring Further Testing

The following conditions are recommended for a test area before full-scale work:

• Thick rubber or thermoplastic road markings.
• Flexible or multi-layer coatings.
• Very soft or deteriorated asphalt.
• Highly textured or uneven concrete.
• Oil-contaminated surfaces.
• Surfaces with embedded metal or loose aggregate.
• Moisture-sensitive coating systems.
• Damaged or spalled substrates.
