Floor shot blasting machine is a mechanical surface-treatment device used to clean, roughen, and prepare concrete, steel, or asphalt floors. It works by centrifugally throwing high-speed steel shots onto the surface through a blasting turbine. The impact removes contaminants and creates a uniform texture. The machine then recycles the steel shots and collects dust, forming a completely closed-circuit cleaning system.
Key Design Bases Used When Designing A Floor Shot Blasting Machine
When we design a floor shot blasting machine, we always follow several key technical basis to make sure the machine can work stable, high-efficiency, and long lifetime in real construction site. The design is not only consider blasting effect, but also consider abrasive recycle, dust control, safety, and easy maintenance.
1. Blasting Requirement Basis
The first basis is the actual working requirement:
- Required working width (200–800 mm)
- Target surface cleanliness and roughness
- Material of ground (concrete, steel plate, asphalt)
- Expected working efficiency (m²/h)
These parameters decide the blasting wheel power, blasting chamber size, and overall structure.
2. Blasting Wheel (Turbine) Basis
The blasting wheel is the heart of the machine. Its design basis includes:
- Motor power and throwing speed
- Blade material and wear-resistance level
- Shot flow control accuracy
- Balance and vibration performance
- Easy replacement design for daily maintenance
Good blasting wheel design ensures strong cleaning force and stable blasting effect.
3. Abrasive Circulation & Separation Basis
A floor shot blasting machine must realize closed-loop abrasive recycle:
- High-sealing blasting chamber to avoid shot leakage
- Efficient recovery path from ground to separator
- Screening system to remove broken shots and dust
- Stable abrasive quantity to keep uniform blasting
This part decides whether the machine can work continuously and economically.
4. Dust Collection & Environmental Basis
Because floor blasting generates large amount of dust, dust control is a key design basis:
- Proper air volume and negative pressure
- Cartridge filter with pulse-jet cleaning
- Airflow direction design to avoid dust accumulation
- Ensure clean operation and meet environmental requirements
A good dust collector makes the machine truly “dust-free construction”.
5. Mechanical Structure & Material Basis
To handle long-time heavy work, the structure must be strong:
- Wear-resistant liners inside blasting chamber
- Thick steel plate frame with anti-vibration design
- High-strength bolts, bearing protection, and wheel load capacity
- Anti-corrosion coating for long service life
These ensure the machine can work reliably in harsh site environment.
6. Walking and Control System Basis
The machine must walk smoothly and be easy to operate:
- Adjustable walking speed to match blasting intensity
- Stable drive wheel design, anti-slip structure
- Simple control panel layout
- Safety interlock between turbine, recovery, and dust collector
This makes operation safer and blasting effect more uniform.
7. Safety & Standard Basis
Design must follow relevant technical standards:
- Electrical safety rules
- Emergency stop and protective covers
- Noise control measures
- CE or other export certifications if needed
Following safety standards improves customer acceptance and reduces risk.
8. Maintenance & Serviceability Basis
In engineering design, we also consider easy maintenance:
- Quick-open covers
- Standard modular parts
- Convenient access to blasting wheel and liners
- Clear maintenance instructions
Good maintainability greatly reduces user downtime.
Conclusion
The design basis of a floor shot blasting machine is a comprehensive engineering system. It must consider blasting performance, structure strength, dust control, safety, and long-term maintenance. Only by following these bases, the machine can provide stable, high-quality surface preparation in different industrial environments.
