Case Study: Raw Material Mill Project at a Kenyan Cement Plant

This high-voltage motor was selected and supplied to drive the main raw material mill at a cement plant in Kenya. Following delivery and on-site installation, it officially entered service in January 2022, handling heavy-duty grinding operations for raw materials such as limestone.

The operating conditions at the cement plant were rigorous: the production area was filled with heavy cement dust, and the raw material mill required frequent heavy-duty, high-torque startups. The fine cement dust posed significant challenges to the motor's sealing, insulation system, and mechanical structure, while the frequent heavy-duty startups placed high demands on the stator-rotor assemblies and bearing systems.

Since commissioning, the motor has demonstrated excellent starting performance, maintaining stable, continuous operation aligned with the plant's production schedule. Long-term on-site monitoring showed vibration levels of 1.0 mm/s, winding temperatures of 80°C, and bearing temperatures of 70°C; all key parameters remained within design limits, fully meeting the requirements for the plant's 24-hour, large-scale continuous production.

Proven through years of actual on-site operation under high-dust, heavy-duty conditions, the motor has demonstrated high reliability with minimal unplanned downtime. The end customer has expressed satisfaction with the motor's stable performance as well as the after-sales technical support, including on-site commissioning and troubleshooting services.
