Case Study: Emergency Spare Parts Supply for 3,000 TPD Cement Plant in Uzbekistan

In March 2026, SMT received an emergency procurement request from a 3,000 TPD cement plant in Uzbekistan. A critical failure of the kiln main drive gearbox had brought production to a complete halt, with estimated losses of $85,000 per day. The client needed replacement components within 15 days or face contractual penalties.

The Challenge

The failed gearbox was a Flender KMPS series unit manufactured in Germany. The client had already contacted the OEM, but the quoted lead time was 12–16 weeks. With production losses mounting, they turned to SMT for an alternative solution.

Key challenges included:

• Identifying a qualified Chinese manufacturer capable of producing the replacement components to OEM specifications
• Verifying material quality and dimensional accuracy within an extremely compressed timeline
• Arranging air freight for oversized gearbox components
• Coordinating customs clearance in Uzbekistan

SMT's Solution

Within 4 hours of receiving the inquiry, SMT's engineering team had identified two qualified suppliers in Jiangsu province capable of manufacturing the required helical gear sets and shaft assemblies. Technical drawings were shared with both suppliers for simultaneous quotation.

By Day 2, a supplier was selected based on technical capability, material certification capability, and price. SMT's quality supervisor was on-site at the factory by Day 3 to witness material procurement and begin dimensional verification.

Quality Control Process

• Day 1–2: Supplier selection, technical agreement, and material procurement
• Day 3–4: Raw material verification (EN10204 3.1 certificates), dimensional pre-check
• Day 5–10: Machining supervision with daily progress reports to client
• Day 11: Final dimensional inspection, hardness testing, surface finish verification
• Day 12: Packaging, dangerous goods marking, air freight booking
• Day 13: Departure from Shanghai Pudong International Airport
• Day 15: Delivery to cement plant site in Uzbekistan

Results

The replacement gear set was installed within 6 hours of arrival. The kiln was back in production on Day 16, with total downtime limited to 16 days versus the 90+ days that would have been required through the OEM channel. The client's total production loss was reduced by approximately $6.3 million compared to the OEM timeline scenario.

Post-installation performance monitoring confirmed that the replacement components met all OEM specifications, with vibration levels within acceptable limits and no abnormal temperature rise during the first 500 hours of operation.

Key Takeaway

This case demonstrates SMT's ability to mobilize quickly for emergency procurement situations. Our pre-qualified supplier network, on-site quality supervision capability, and logistics expertise enable us to compress procurement timelines that would otherwise take months into days.
