​Roller Conveyor Shot Blasting Machine

    The Steel Structure Shot Blasting Machine is a fully automatic, continuous surface treatment equipment. It is mainly used for surface cleaning or strengthening of main steel structures such as H-beams and box columns in construction, as well as steel beams, columns, and trusses in industrial workshops. It is applied for rust removal, oxide scale removal, welding slag cleaning, and surface strengthening of steel structural components (e.g., H-beams, I-beams, channel steels, steel plates, box girders, etc.).

一. Core Working Principle

• Conveying: Workpieces are conveyed through the blasting chamber at a constant speed by a roller conveyor system.

• Blasting: Multiple high-efficiency blast wheels propel steel shots at high speed from different angles to impact the workpiece surface.

• Recycling: Steel shots are recycled through screw conveyors, bucket elevators, and abrasive separators, while dust is purified by a dust removal system.

• Unloading: Finished workpieces are automatically conveyed to the next process.

二. Main Structural Components

• Blasting Chamber: Equipped with wear-resistant protective plates to prevent shot splashing and ensure service life.

• Blast Wheel Assembly: Cantilever centrifugal design, featuring large shot capacity, high efficiency, and long service life of wearing parts.

• Roller Conveyor System: Adjustable speed to accommodate continuous conveying of workpieces of different specifications.

• Abrasive Circulation System: Enables automatic recovery, separation, and reuse of steel shots, reducing operating costs.

• Dust Removal System: Adopts pulse cartridge filtration to ensure compliance with dust emission standards and improve the workshop environment.

• Electric Control System: PLC + touch screen control, allowing automatic/manual switching for convenient operation.

三. Core Advantages

• High Efficiency & Continuity: Suitable for mass processing of steel structural components, with efficiency dozens of times higher than manual cleaning or pickling.

• High Derusting Grade: Can reach Sa2.5–Sa3 grade, meeting high-standard coating requirements.

• Environmental & Safe: No pickling waste liquid, avoiding chemical pollution and safety hazards.

• Surface Strengthening: Forms a compressive stress layer on the workpiece surface, improving fatigue resistance and corrosion resistance.

• High Degree of Automation: Reduces manual intervention, lowers labor intensity, and enhances product consistency.

四. Application Scenarios

• Pretreatment of steel structural components in industries such as steel structure workshops, bridges, wind turbine towers, and engineering machinery.

• Rust removal and pre-coating treatment of steel plates, section steels, and profiles.

• Refurbishment, paint removal, and recoating of old steel structural components.
