The overhead shot blasting machine is available in single and double hook models. The machine loads workpieces alternately into the shot blasting cleaning chamber using two hooks. The blast gun propels shots ranging from 0.2 to 0.8 mm towards the workpiece surface, achieving a certain roughness to enhance appearance or alter the compressive stress to extend the workpiece's lifespan. This model is widely used for surface cleaning or strengthening treatment of medium and small castings and forgings in industries such as foundry, construction, chemicals, motors, and machine tools. Additionally, it is suitable for cleaning slender, thin-walled parts that are prone to damage.

Shot Blasting Adjusting Method

When adjusting the shot blasting gun of a hook-type shot blasting machine, attention should be given to the position of the directional sleeve of the shot blasting gun. The shot should cover the workpiece being cleaned entirely; otherwise, it will affect the cleaning efficiency.

Position the directional nozzle window; if necessary, mark the board with black ink or lay a thick paper on the cleaned workpiece location. Start the shot blasting machine, manually add a small amount of shot into the feeding tube of the machine, check the position of the projection belt. If the projection area is not positioned correctly, adjust the directional nozzle to achieve the desired position.

Advantages

Utilizing the fourth-generation international overhead centrifugal shot blasting machine with high shot volume and projection speed, it can significantly enhance cleaning efficiency and achieve satisfactory cleaning quality.

2. The simulation projection diagrams (including the determination of shot blaster models, quantities, and spatial layout positions) and all drawings of the shot blasters are fully created using Computer-Aided Design (CAD), making the selection and arrangement of shot blasters more rational. This improves the utilization rate of shot pellets and labor productivity, ensures the cleaning effect, and reduces wear on the chamber's protective panels.

3. Utilizing the popular underground pitless structure, it saves both construction costs and time for the pit foundation, while also resolving the issue of ball and sand corrosion and lump formation inside the hoist due to water accumulation in the pit for southern users.

4. Indoor hot zone cleaning utilizes rolled Mn13 plate protection, which significantly increases service life compared to the previous rubber plate protection, while also being aesthetically pleasing and easy to replace.
