A floor shot blasting machine is a mechanical surface treatment device that uses a high-speed rotating blasting wheel to throw steel shots onto the ground surface at high speed. After the steel shots hit the surface, they quickly remove laitance, oil stains, rust, old coatings, and other impurities, creating a uniform rough surface. This process greatly improves the adhesion of coatings, waterproof layers, and paving materials. The floor shot blasting machine mainly consists of two parts: the blasting machine body and a reverse-pulse dust collector. The two systems are connected through a 20-meter dust collection hose and a 23-meter power cable. The equipment is widely used in highway construction, bridge engineering, airport runway maintenance, industrial workshops, parking lots, and epoxy floor projects. Compared with traditional grinding methods, a floor shot blasting machine offers higher efficiency, better cleaning performance, and environmentally friendly construction.

5 Working Principles of Floor Shot Blasting Machines
- High-Speed Blasting: After the equipment starts, the blasting system rotates at high speed and throws steel shots onto the ground at a specific angle and speed.
- Surface Impact: The high-speed steel shots continuously impact the working surface, creating a uniform rough texture while removing laitance, oil stains, old coatings, and other surface residues.
- Steel Shot Recycling: The machine includes an automatic recycling system that collects used steel shots and reuses them, reducing material consumption and operating costs.
- Impurity Separation: The vacuum airflow generated by the dust collector separates steel shots from dust and impurities removed during construction.
- Dust-Free Collection: Dust enters the dust collection system for centralized processing, allowing low-dust and environmentally friendly construction while improving the working environment. A modern automatic shot blasting machine can perform these processes continuously, which greatly improves construction efficiency.
4 Working Conditions of Portable Shot Blasting Machines
- Ground Conditions: The ground should be uneven by less than 10mm. The surface should be dry, without standing water, and the slope should be less than 25°.
- Temperature Requirements: The working temperature range is from -20℃ to 60℃. The steel plate surface temperature should be at least 3℃ above the dew point.
- Humidity Requirements:
Relative humidity for steel surface blasting should not exceed 90%.
Relative humidity for concrete blasting should not exceed 95%. - Altitude and Weather: The operating altitude range is 0–3000 meters. The equipment should not be operated in rainy or snowy weather.
8 Features of Concrete Shot Blasting Machines
- High Construction Efficiency: A floor shot blasting machine can quickly complete large-area surface cleaning and roughening work, greatly shortening the construction period compared with manual grinding.
- Uniform Surface Treatment: The high-speed steel shots evenly impact the surface, removing impurities and creating a consistent rough texture for better coating adhesion.
- Environmentally Friendly Dust-Free Operation: The equipment includes a professional dust collection system that simultaneously recovers dust and impurities, reducing pollution during construction.
- Reusable Steel Shots: The machine automatically recycles steel shots for repeated use, reducing material waste and operating costs.
- Reduced Labor Costs: Mechanical construction reduces the need for manual labor. One machine can replace several workers, improving efficiency and reducing labor expenses.
- Wide Application Range: The floor shot blasting machine is suitable for highways, bridges, airport runways, industrial floors, parking lots, and steel structure rust removal.
- Easy Operation and Durability: Modern equipment usually adopts intelligent control systems for easy operation. Core parts are made of high-strength wear-resistant materials for long service life.
- Improved Construction Safety and Quality: The machine can work continuously and stably while reducing direct worker exposure to dust and dangerous environments.
