The crane shot blast machine is available in single crane and double crane models. The crane shot blast machine loads workpieces alternately into the shot blasting cleaning chamber using two cranes. By utilizing a shot blasting gun, shots of 0.2 to 0.8 mm in size are propelled onto the workpiece surface, achieving a certain degree of roughness. This not only enhances the appearance of the workpiece but also alters the compressive stress to increase its lifespan. This model is widely used in the surface cleaning or strengthening treatment of medium and small castings and forgings in industries such as foundry, construction, chemicals, electrical machinery, and machine tools. Moreover, it is suitable for cleaning slender, thin-walled parts that are prone to damage.

Shot Blasting Adjusting Method

When adjusting the shot blasting pot for the hook-type shot blasting machine, pay attention to the position of the directional sleeve of the shot blaster. Ensure that the pellets are projected to fully cover the workpiece being cleaned; 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 it, place it at the location of the cleaned workpiece, start the shot blasting machine, manually add a small amount of shot into the shot feeder of the blasting machine, check the position of the projection belt. If the position of the projection area is incorrect, adjust the directional nozzle to achieve the ideal position.

Advantages

Utilizing the fourth-generation international overhead centrifugal shot blasting machine with high shot blasting volume and 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 blasting machine are completely designed using Computer-Aided Design (CAD), making the selection and arrangement of shot blasters more rational. This improves the utilization rate of abrasive shots and labor productivity, ensures cleaning effectiveness, and reduces wear on the chamber protective panels.

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

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