Project Case Study

This port facility in the Gulf of Guinea, handling 45 million tons of iron ore annually, faced three major operational challenges: 3-meter tidal variations, high salt spray corrosion, and stringent EU dust emission standards. The project required an unloading system that could seamlessly integrate with mobile shiploaders, achieve single-line throughput exceeding 6,000 tph, and maintain real-time PM10 levels below 10mg/m³.

The ZOOMRY engineering team selected the ZRLS-TU1800 wheeled truck unloader as the core equipment. Its 5.7-meter extra-wide hopper accommodates rapid unloading of 120-ton mining trucks, while the laser positioning system maintains vehicle alignment within ±15cm accuracy. Through OPC UA protocol integration with the ZRSL-60 mobile shiploader, the system automatically increases shiploader belt speed from 3.15m/s to 4.0m/s when unloading reaches 1600t/h, achieving 28% higher coordinated efficiency.

For dust control, an innovative two-stage "source suppression + terminal collection" system was implemented. Micron-level dry fog devices at the hopper area reduce PM10 to 8.2mg/m³, while pulse-jet filters at transfer points further control dust levels below 6.5mg/m³. Third-party verification confirmed these emissions outperform ISO 34001:2019 standards by 23%.

During 18 months of operation, key performance metrics exceeded expectations: peak daily throughput reached 72,000 tons (20% above design capacity), energy consumption stabilized at 0.18kWh per ton (34% reduction from previous systems), and Overall Equipment Effectiveness (OEE) maintained at 94.7%.
