Application Case Study of a Mesh-Belt Shot Blasting Machine in the Shot Blasting and Cleaning of Automotive Electric Motor Systems
Primary models purchased:
1. Mesh-belt pass-through shot blasting machine: MND-1030P11-4, Quantity purchased: 1 unit;

Applications:
Used for shot-blasting and rust removal on precision castings—such as hardware fittings, vehicle parts, brake pads, valves and pipe fittings, and mechanical components made of carbon steel, stainless steel, alloy steel, or special steel—particularly for parts requiring the cleaning of only a single surface.
Key features of this machine:
1. The shot blasting chamber features a body constructed entirely of manganese steel, guaranteed against structural failure for 20 years. The interior is lined with double-layer wear-resistant manganese steel plates secured by high-durability nuts. Double-opening access doors facilitate maintenance and liner replacement, significantly enhancing serviceability;
2. A motor-driven mesh belt conveyor ensures a long service life and smooth transmission; all linked mechanisms are equipped with protective devices and warning signs;
3. The shot blasting chamber features a compact, sealed design to prevent shot leakage or splashing;
4. It utilizes the KEEJOO cast-type shot blasting power system, featuring variable frequency speed control and a semi-automatic flow control valve; this system offers a very low failure rate and high shot delivery efficiency. (Alternatively, the Chunjiu P-series system is available, featuring a custom ABB motor; all internal wear parts of the blast head undergo precision CNC machining using mold steel followed by low-pressure vacuum heat treatment, achieving a surface hardness of 58–62 HRC and exceptional wear resistance, thereby greatly extending service life);
5. Steel shot recovery is handled by a reliable system combining a screw conveyor and a bucket elevator;
6. A Venturi-type dust collector is employed—a new-generation model further developed by Chunjiu. It offers fire and explosion safety, requires no spare parts (minimizing long-term maintenance costs), and ensures dust emissions remain below 50 mg/m³;
7. The electrical system utilizes Siemens components, featuring a 7.3-inch color touchscreen HMI with 3D animated guidance; the interface is user-friendly and highly functional;
8. All equipment labeling is correctly positioned; safety warnings, maintenance reminders, operating procedures, equipment status indicators, after-sales service contact cards, and service logs are clearly visible at a glance;
9. All maintenance access doors are equipped with safety interlocks; in an emergency, the safety control device can be activated immediately to facilitate systematic troubleshooting based on the fault location;
10. The entire machine is designed and manufactured to European CE standards; all mechanical and electrical components are integrated to ensure optimal safety and operational stability.
