With 17+ years of dedicated deep industry experience starting from workshop assembly, Zhang has mastered the full life cycle of CLUM vertical roller mills. As a strategic project helmsman, he specializes in mega-project contingency planning and the expert control of rare materials via deep experience in core parameter fine-tuning. Highlights include his three-year management of our domestic client RONGSHENG , overseeing 10 clustered units representing over 100 million RMB. Zhang is trusted for delivering stable lines exceeding 500,000 tons annually.

Zhao has a natural talent for mechanical diagnostics, a skill developed through years of experience in precision automotive repair. This “Mechanical Detective” approach helps him identify the root cause of issues—such as subtle vibrations or gear alignment problems—that standard tools might miss. Zhao specializes in leading large installations for major international clients, such as the three-unit ZLK project in Pakistan. He turns complex setups into synchronized systems and provides pragmatic training so client teams can run their lines with total confidence.

Liu Jianqiang is recognized as a versatile, all‑around expert with over 11 years of field experience across Clirik’s core product portfolio. He is widely trusted for his integrity and his consistent focus on protecting client interests.
Known for his exceptional hands‑on capability, Liu is often requested by name for the most challenging sites. He is characterized by a “whatever it takes” approach—personally resolving complex technical bottlenecks and even taking on manual work when local crews are unavailable to keep projects on schedule. Detail‑oriented and disciplined in execution, Liu drives each unit to stable, peak performance through rigorous, standards‑driven commissioning.

With over 4 years of industrial experience rooted in Main Unit assembly, Zhang Yuankui bridges the gap between factory-standard precision and complex field conditions. Specializing in the HGM series, he has built a reputation for his patient, systematic approach to client empowerment, ensuring that site teams fully master equipment logic beyond basic operation.
Zhang’s technical agility was notably demonstrated during a May 2025 domestic project, where he led the modernization of a legacy milling site. Tasked with integrating an HGM125 into an extremely confined space, he performed detailed manual surveying and produced on-site technical sketches. These sketches were critical in coordinating with Clirik’s engineering department to deliver customized, high-precision installation drawings. He is a careful listener who ensures that every technical constraint—be it space or process—is resolved with a workable, engineered solution.

With a 13-year technical pedigree, including a decade in electrical distribution assembly, Guo Yanfei is a lead specialist for Clirik’s mission-critical electrical architecture. He specializes in the electrical integration of vertical roller mill (VRM) lines, excelling where standard layouts reach their limits. Known for disciplined execution and meticulous wiring standards, Guo ensures every control cabinet is engineered for long-term stability in harsh industrial environments. On large-scale automated lines, he serves as the essential link between power systems and reliable performance.

Since 2005, Yang Kai has spent over 21 years mastering the internal logic of heavy-duty electrical architecture. He believes that the most robust control programs aren’t written in a lab—they are forged in the dust, heat, and unpredictable variables of the world’s most demanding production sites.
Forged from the Field: Advanced Transmission & Operational Protection Yang’s expertise is built on a foundation of real-world problem-solving. By analyzing patterns from countless client cases, he has integrated specialized Reduction Gear Transmission Protection and No-load Protection into Clirik’s control systems. The former prevents irreversible damage to core drive components during load surges, while the latter automatically detects idle states to eliminate energy waste and unnecessary mechanical wear. These features have become the “invisible safety belts” for Clirik’s high-performance mills.
The “Remote Surgeon” in a Global Crisis During the peak of global travel restrictions, Yang resolved a critical production bottleneck for a client in India entirely through remote data synthesis. By performing a “deep dive” into operational currents and frequency patterns from thousands of miles away, he pinpointed a subtle parameter misalignment that on-site teams had overlooked. Without a single engineer boarding a plane, Yang restored the plant to full capacity through precise, remote recalibration.
Hardened Engineering for Extreme Environments For projects in 48°C (118°F) environments like rural India, Yang treats electrical cabinets as “survival capsules.” Moving beyond standard assembly, he re-engineers systems with customized dual 1500W industrial AC modules, reinforced sealing (IP20/IP21 optimization), and integrated thermal monitoring. These “hardened” solutions have maintained stable operation for two years to date in the face of high heat, humidity, and altitude.
