AI Technical Summary
Traditional sandblasting machine abrasive components such as hammers are fixed by welding or complex bolts, which makes replacement time-consuming and labor-intensive, results in long equipment downtime, high cost of replacing the entire liner, serious waste of resources, and inconvenience of maintenance.
The modular design of the hammer and liner allows for quick assembly and disassembly via fixing bolts and sleeve structure. Combined with spring buffer and adjustable arc-shaped filter plate, it enables rapid replacement and maintenance of the abrasive assembly.
Significantly reduce equipment downtime, lower maintenance costs, improve work efficiency, reduce labor burden, and adapt to different granularity requirements.
