Hanger-Type Shot Blasting Machine

The Hanger-Type Shot Blasting Machine, often utilized as a Spinner Hanger system, stands as one of the most versatile and robust solutions in the industrial surface preparation sector. It is specifically recommended for applications involving components that are too large, heavy, or geometrically complex to be batch-tumbled, such as descaling, rust removal, and stripping old coatings/paint. This system ensures a consistent and uniform abrasive impact across the entire surface of the workpiece, guaranteeing a flawless surface profile.

Comprehensive Operational Principle

The machine's operation is meticulously designed for maximum efficiency and detailed cleaning. Workpieces are carefully loaded onto custom-designed, rotating hooks (hangers), typically aided by manual handling, a hoist, or an integrated overhead conveyor system (which can be a linear monorail, Y-rail, or closed-loop power & free setup). Once the parts are secured, the hanger transports them into the enclosed blast chamber. The safety-interlocked door of the chamber is then closed, and the hangers begin to rotate the workpieces continuously 360 degrees on their vertical axis.

During this rotation, multiple high-speed centrifugal blast wheels (ranging typically from 2 to 7 units) are activated. These turbines propel abrasive media—such such as steel shot, steel grit, or even glass beads—at high velocity (some models reaching up to 3000 RPM) onto the rotating parts from various strategic angles. The high throughput and velocity of the abrasive media ensure comprehensive coverage, allowing the blast stream to reach every nook, corner, and complex contour. This method is crucial for achieving the specified surface roughness (e.g., SA 2.5 or SA 3 standards) required for optimal adhesion of subsequent protective coatings like paint, powder coating, or galvanizing.

Application Spectrum and Industrial Use

The versatility and power of the Hanger-Type shot blasting machine make it indispensable across a wide range of heavy industries:

• Automotive and Heavy Vehicle Manufacturing: Cleaning and shot peening of large structural components, including truck chassis, engine blocks, axles, and wheel rims.

• Construction and Structural Steel: Surface preparation of structural steel beams, columns, and large welded fabrications, effectively removing mill scale and rust prior to welding or coating applications.

• Foundry and Forging: Cleaning castings, forgings, and heat-treated parts to remove burned-on sand, oxide scale, and burrs, preparing them for the next stage of manufacturing.

• Power and Conveying Systems: Surface treatment for crane components, large valves, piping, and parts for heavy carrier systems.

Technical Superiority and Operational Benefits

The machine’s superior performance is driven by innovative design features:

1. Scalable Capacity and Flexibility: Hook load capacities are highly flexible and can be scaled according to the part size and weight, typically ranging from a minimum of 500 kg up to 10 tons. Systems can be configured as single-hook batch operations or continuous Y-rail dual-hook systems to minimize idle time and maximize throughput.

2. Exceptional Wear Resistance: The blast chamber is lined with highly durable materials, such as Manganese Steel armor plates and often reinforced with rubber sheets in specific impact zones. This extends the machine's service life and significantly reduces maintenance costs associated with wear and tear.

3. Efficient Media Management: An integrated abrasive recycling system continuously cleans and reconditions the used blast media via sieves and magnetic separators. This process drastically reduces media consumption costs while ensuring the blast stream maintains consistently high quality.

4. Full Automation and Safety: The entire operation (hook movement, turbine control, and blast cycle time) is managed by a PLC automation panel, often featuring a 10-inch touchscreen HMI. Safety is paramount, with interlock systems and sensors preventing operation unless doors are securely closed, ensuring maximum operator safety.

5. Environmental Compliance: The closed-loop operation, coupled with a high-capacity filtration and dust collection system (air flow rates up to 6000 m³/h), effectively contains dust and particles, maintaining a clean working environment and ensuring full compliance with environmental regulations.

The Hanger-Type Shot Blasting Machine is a cost-effective and highly efficient investment that optimizes surface preparation processes in heavy industry. Custom manufacturing options are available to meet specific industrial requirements regarding requested sizes, dimensions, and load capacities.
