What is Hook Shot Blast Machine?

A Hook Shot Blast Machine is a specialized industrial device used for surface cleaning, rust removal, and shot peening of various workpieces, particularly those that are fragile, irregularly shaped, or too large to be processed in bulk. The machine is widely used in industries such as casting, forging, construction, automotive, and shipbuilding.

Key Features and Components

1.Main Blast Cabinet:

Equipped with an inspection door for maintenance and monitoring.

2.Blast Wheel Units:

High-efficiency blast wheels propel abrasive media (such as steel shot or grit) at high speed onto the workpieces.

3.Rotating Hooks:

Workpieces are suspended from rotating hooks that move through the blast chamber, ensuring all surfaces are exposed to the abrasive media.

4.Abrasive Circulation System:

Includes a bucket elevator, screw conveyor, and separator to recycle and clean the abrasive media, reducing waste.

5.Dust Collection System:

Integrated dust collection system captures and filters dust generated during the blasting process, ensuring environmental compliance.

6.Control System:

Equipped with a PLC (Programmable Logic Controller) system for precise control over the blasting process.

Working Principle

1. Loading: Workpieces are suspended from hooks and placed in the work area of the machine.

2. Rotation: The hooks begin to rotate, exposing all angles of the workpiece surface to the shot blasting process.

3. Shot Blasting: High-speed rotating blast wheels propel abrasive particles onto the workpiece surface, removing rust, scale, and other impurities.

4. Recovery and Reuse: Used abrasive particles are collected, screened, and cleaned for reuse.

5. Unloading: After the cleaning cycle is complete, the workpieces are unloaded and inspected.

Technical Parameters

1. Maximum Cleaning Weight: Ranges from 500 kg to 10,000 kg depending on the model.

2. Abrasive Flow Rate: Typically 2x200 kg/min to 5x250 kg/min.

3. Ventilation Capacity: 5000 m³/h to 16000 m³/h.

4. Hook Dimensions: Vary from Ø600x1200 mm to Ø3000x3000 mm.

Applications

1. Surface Cleaning: Removing rust, scale, and other contaminants from castings, forgings, and welded structures.

2. Shot Peening: Increasing surface roughness and fatigue strength of workpieces.

3. Preparation for Coating: Creating a uniform surface texture suitable for painting or coating.

Benefits

1. High Efficiency: Continuous operation and automated process ensure high production rates.

2. Versatility: Suitable for a wide range of workpiece sizes and shapes.

3. Environmental Protection: Enclosed system and dust collection minimize environmental impact.

4. Customization: Machines can be tailored to meet specific requirements, including workpiece size and production capacity.

Hook Shot Blast Machines are ideal for industries requiring high-quality surface treatment of large and complex components, ensuring durability and longevity of the finished products.
