Case Study: Mining Crushing Project in Uzbekistan

This high-voltage motor was specifically selected to drive the primary ore-crushing equipment at an open-pit mine in Uzbekistan. Delivered, installed on-site, and officially commissioned in August 2020, it powers the heavy-duty crushing of hard ore within the mineral processing line.

Located in a remote, inland Gobi Desert region, the site presents harsh operating conditions: pervasive airborne dust, scorching summer heat, significant diurnal temperature fluctuations, and limited on-site maintenance infrastructure. The ore-crushing process generates frequent, high-impact loads, placing rigorous demands on the motor regarding mechanical structural strength, dust-proof sealing, heat dissipation, and impact resistance.

Since commissioning, the motor has operated stably under full load and periodic impact loads, aligning with the mine's 24-hour production schedule. Long-term on-site monitoring data shows vibration levels ≤1.1 mm/s, a peak winding temperature of 81°C, and a bearing temperature of 72°C. All key operating parameters remain within design limits, demonstrating the equipment's robust resilience against the frequent impact loads inherent to the crushing operation.

After years of continuous on-site operation, the motor has experienced no major failures or unplanned downtime, effectively reducing maintenance requirements and minimizing production losses caused by equipment issues. The overseas end-user has highly recognized the motor's reliable performance under the demanding heavy-duty conditions of the Gobi mine; based on this positive operational feedback, they subsequently placed additional orders for motors from the same series to support the mine's capacity expansion.
