Steel Structure Shot Blasting Machine

    Steel Structure Shot Blasting Machine is a fully automatic, continuous surface treatment equipment. It is mainly used for surface cleaning and strengthening of main steel structures, such as H-beams and box columns for construction, as well as steel beams, columns, and trusses in industrial workshops. It performs rust removal, descaling, welding slag cleaning, and surface strengthening for steel structural parts, including H-beams, I-beams, channel steels, steel plates, box girders, etc.

一. Core Working Principle

• Conveying: Workpieces pass through the blasting chamber at a constant speed via the roller conveyor system.

• Blasting: Multiple high-efficiency blast wheels throw 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 the dust removal system.

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

二. Main Structure Components

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

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

• Roller Conveyor System: Adjustable speed for continuous conveying of workpieces with different specifications.

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

• Dust Removal System: Adopts a pulse cartridge dust collector to ensure compliant dust emission and improve the workshop environment.

• Electrical Control System: PLC + touch screen control, supporting automatic/manual switching for easy operation.

三. Core Advantages

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

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

• Eco-friendly & Safe: No pickling waste liquid, avoiding chemical pollution and potential safety hazards.

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

• High Automation: Reduces manual intervention, lowers labor intensity, and improves product consistency.

四. Application Scenarios

• Pretreatment of steel structural parts in steel structure workshops, bridges, wind turbine towers, engineering machinery, and other industries.

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

• Refurbishment, paint stripping, and recoating of used steel structural parts.
