A shot blasting machine is an industrial device that mechanically propels metal shot at high speed onto the surface of a workpiece. It utilizes centrifugal force to throw a large amount of steel shot at the workpiece, removing surface oxide scale, rust, welding slag, and other impurities through physical impact, while simultaneously creating a uniform rough surface, providing an ideal adhesion base for subsequent coating processes. This surface treatment method not only improves the appearance quality of the workpiece but also enhances its corrosion resistance and service life.
Depending on the shape and size of different workpieces and production needs, shot blasting machines have developed various structural forms. Common types include hook type, drum type, tracked type, and rotary table type. Tracked shot blasting machines are particularly suitable for processing small and medium-sized castings, forgings, and standard parts, featuring continuous operation, large throughput, and ease of operation.
The Q32 series crawler-type shot blasting machine features a continuous conveying design, with workpieces constantly rotating during the cleaning process to ensure uniform treatment of all surfaces. The equipment has a compact structure, requires no special foundation, and is easy to install and debug. Compared to traditional methods, the Q32 series improves work efficiency by over 30% while maintaining consistent processing quality.
The equipment is equipped with multiple high-efficiency shot blasters, projecting the workpiece from different angles. The shot blasting chamber uses high-chromium wear-resistant plates to ensure long-term stable operation. The shot circulation system includes a magnetic separator and a vibrating screen, effectively separating impurities and ensuring shot blasting quality. The surface cleanliness of the treated workpieces can reach Sa2.5 standard.

The equipment adopts a modular design and is available in various sizes. The standard model has a processing capacity from 200 kg to 1000 kg per pass, with a typical single workpiece weight not exceeding 50 kg. The equipment width ranges from 600 mm to 1200 mm, accommodating the processing needs of workpieces of different sizes.
The equipment is equipped with a user-friendly control system with a clear and concise operating interface. Simply set the processing time and shot blasting intensity, and the equipment will automatically complete the entire process. The track speed can be steplessly adjusted between 0.5 m/min and 4 m/min to adapt to different materials and process requirements.
