DECENT MACHINERY & World’s 2nd-Largest Metal Mine: Custom Explosion-Proof Fan System Delivered Successfully​

Posted on 2025-11-17

Recently, DECENT MACHINERY successfully delivered a customized project for underground explosion-proof fans and control systems in collaboration with the world’s second-largest metal mine. With the core advantages of "rapid response, precise customization, rigorous quality, and full-chain service", we have won high trust from the partner and consolidated our position as a benchmark in high-end equipment services for overseas mining.
I. Rapid Response for Efficient Demand Alignment​
During the project, the partner raised detailed questions on core demands including equipment control principles, explosion-proof safety, component selection, and multilingual adaptation. DECENT MACHINERY set up an exclusive docking mechanism to respond immediately, deliver solutions quickly, and efficiently provide drawings, image materials, and configuration lists. With "instant response and efficient implementation", the project progressed seamlessly.
II. In-Depth Customization for On-Site Requirements​
To meet the mine’s strict needs (underground gas environment, 3-year 24/7 continuous operation), DECENT MACHINERY developed a comprehensive customization plan:
  • (1)Core Configuration: Siemens frequency converter + PLC, adapted to 400V 50Hz, protection class up to IP56;
  • (2)Structural Design: Control cabinet (715×530×1100mm, ~525kg) with 6mm-thick radiator + heat transfer fluid air-cooling system, plus dust-proof filters and baffles to eliminate dust and high-temperature issues;
  • (3)Detail Adaptation: No Chinese logos on equipment/packaging; Russian + German on control panels; 6mm casing for 30-year service life in underground corrosion-free environments.
  •  

III. Rigorous Quality Control with Authoritative Certification​
DECENT MACHINERY follows standardized quality control SOP, with strict checks from component selection to production and assembly. Before delivery, international third-party organization BV was invited to conduct a comprehensive inspection (covering explosion-proof performance, operational stability, etc.), ensuring compliance with overseas mining standards. The company fulfilled its commitment: 30-day production cycle and 3-year continuous stable operation.
 

 
IV. Full-Chain Service for a Worry-Free Experience
DECENT MACHINERY has built a full-process service chain: "demand docking → scheme design → data delivery → production → third-party inspection → follow-up support". It provides Russian-version manuals, equipment images, and full-process follow-up on customer inquiries, safeguarding cooperation with standardized services.



 
DECENT MACHINERY will continue to focus on overseas mining scenario needs, leveraging more professional customization capabilities, stricter quality control, and a more complete service system to provide global customers with efficient, safe, and long-term equipment solutions, and jointly promote high-quality development of the mining industry.
