How a typical hook type shot blasting machine operates

A hook type shot blasting machine is a type of industrial equipment used for surface preparation, cleaning, and finishing of metal parts or components. It is particularly suited for larger or heavier parts that cannot be tumbled, such as castings, forgings, welded structures, and fabricated components. The "hook" refers to the mechanism used to suspend and move the parts through the blasting process.

Here's how a typical hook type shot blasting machine operates:

1. Loading: The parts or components to be blasted are hung on hooks or suspended from overhead conveyors. The hooks are typically attached to an overhead monorail or trolley system that moves the parts through the blasting chamber.

2. Blasting Chamber: Once loaded, the parts enter the blasting chamber, which is equipped with one or more blast turbines or wheels. These turbines or wheels are positioned strategically around the chamber to direct a high-velocity stream of abrasive media (such as steel shot, grit, or abrasive particles) onto the surfaces of the parts.

3. Blasting Process: As the parts move through the blasting chamber, they pass in front of the blast turbines or wheels, which propel the abrasive media at high speed onto the surfaces of the parts. The kinetic energy of the media removes surface contaminants, scale, rust, paint, or other unwanted coatings, leaving behind a clean and uniformly roughened surface.

4. Dust Collection: During the blasting process, dust, debris, and spent abrasive media are generated. A dust collection system within the machine captures and removes these contaminants from the blasting chamber, maintaining a clean working environment and preventing the accumulation of debris.

5. Media Recovery and Recycling: Many hook type shot blasting machines feature a media recovery and recycling system. This system collects the spent abrasive media, separates it from the debris, and recycles it for reuse in subsequent blasting cycles. This not only reduces waste but also helps minimize operating costs.

6. Unloading: After the blasting process is complete, the parts exit the blasting chamber and are unloaded from the machine. Depending on the specific application, additional post-processing steps such as rinsing, drying, or coating may be required before the parts are ready for further assembly or finishing.

Hook type shot blasting machines offer efficient and effective surface preparation for a wide range of metal parts and components. They are widely used in industries such as automotive, aerospace, foundry, and manufacturing, where high-quality surface finishes and precise cleaning are essential for the production of durable and reliable products.
