Fully automatic dual-hook shot blasting machine used for rust removal and cleaning of fire extinguisher cylinder surfaces.

Primary models purchased:

1. Double-hook type shot blasting machine: HSK90-11-3, Quantity: 1 unit;

Applications:

Used for surface cleaning of various items, such as fire extinguisher cylinders, liquefied gas cylinders, sheet metal parts, machinery frames, and castings.

Main features of this machine:

1. The machine body is fabricated from welded wear-resistant steel plate, guaranteed against structural failure for 20 years; the interior features suspended, double-layer wear-resistant manganese steel liners that are easy to replace, significantly enhancing maintainability;

2. Features a Y-shaped, dual-station rail system for material loading and unloading; loading, unloading, and material transfer are manually controlled (eliminating safety risks associated with fully automated operation);

3. The blast chamber utilizes a compact, sealed design to ensure no abrasive media escapes;

4. Equipped with a "Meifulai" (MFL) blast wheel powertrain system featuring high-performance blast wheels and semi-automatic flow control valves; blast flow can be regulated directly from the control panel, greatly improving blasting efficiency;

5. A reliable and stable bucket elevator system is used for steel shot recovery;

6. The dust collection system employs a pulse-jet cartridge dust collector; it is fire-safe, requires no replacement parts, offers low operating costs, and ensures dust emissions remain below 30mg/m³;

7. The electrical system utilizes Siemens components; the HMI features a 10-inch color touchscreen with 3D animated guidance, offering a user-friendly interface and powerful functionality;

8. All equipment labeling is correctly applied and clearly visible, including safety warnings, maintenance reminders, operating procedures, equipment status indicators, after-sales service contact cards, and service logs;

9. All motors utilize direct-drive transmission—eliminating belts and chains—which significantly enhances both safety and ease of maintenance.
