[Zhengzhou, China] - We are pleased to announce the successful factory testing, packing, and container loading of a complete 30–50 TPH Placer Gold Washing Plant bound for Nigeria. The complete set includes our high-performance GMTS-1225 Alluvial Gold Trommel Screen, heavy-duty gold recovery sluice boxes with premium gold-catching matting, and an independent diesel generator set designed specifically for off-grid field operations.
1. Project Background & Site Requirements
The client operates an alluvial/placer gold mine in Nigeria with raw feed consisting of river gravel, coarse sand, and loose alluvial deposits. The main operational requirements were:
- Target Capacity: 30 to 50 tons per hour (TPH) continuous processing.
- Off-Grid Power Requirement: Remote site conditions without access to stable grid power, requiring a integrated diesel generator power package.
- High Gold Recovery Rate: Effective washing and sizing to ensure fine free-gold capture without slurry loss.
2. Integrated Solution & Machine Configuration
To match the site conditions and feed characteristics in Nigeria, our engineering team provided an all-in-one mobile processing solution:
- GMTS-1225 Gold Trommel Screen: Engineered with a 1200mm drum diameter and 2500mm drum length, featuring internal high-pressure water spray pipes and heavy-duty screen mesh for optimal clay disintegration and sizing.
- Gold Recovery Sluice Box System: Paired with specialized high-capture gold matting (gold carpet) to trap both fine and coarse placer gold efficiently.
- Industrial Diesel Generator Set: Delivers independent, stable electric supply to drive the trommel motor and water pumps seamlessly in field environments.

3. Communication Journey & Cooperation History
The successful dispatch of this equipment marks another milestone in our partnership with mining clients in West Africa:
- Initial Inquiry & In-Depth Technical Consultation: When the client first reached out, our team analyzed their raw material characteristics (particle sizing, clay ratio, and hourly tonnage needs). Through detailed technical calls and CAD layout share-outs, we confirmed the GMTS-1225 model as the most cost-effective and productive match.
- Customized Modifications: Considering local operational field conditions, our engineers reinforced the mobile chassis structure and optimized the internal water distributor arrangement to maximize washing efficiency before material flows onto the sluice.
- Transparent Pre-Shipment Testing: After manufacturing, complete no-load trial runs and water spray tests were conducted at our facility. Full video documentation was shared with the client for real-time online inspection, receiving high recognition for build quality and transparency.
Client Feedback: "The Sinolion team demonstrated exceptional technical responsiveness. Their ability to deliver a turnkey package-from trommel screen to sluice box and generator set within 20 days-exceeded our expectations."
4. Packing, Loading & Next Steps
All equipment components underwent anti-rust treatment, heavy-duty wrapping, and careful container loading at our factory to prevent damage during sea transportation. The shipment is now on its way to the port of entry in Nigeria.
Our customer service and technical support teams will continue to track the shipment and provide full remote installation guidance, electrical wiring diagrams, and operational training once the equipment arrives on site.
