Trommel Screen Combined with Sluice Box | Heavy Duty Alluvial Gold Washing Plant
1. Product Overview
The trommel screen combined with sluice box is a heavy-duty, high-capacity alluvial gold washing and separation system designed for large and medium-scale river gold mining projects. Different from mini portable gold equipment, this industrial-grade trommel sluice unit supports continuous high-tonnage material processing, effective mud removal, particle screening and gold gravity recovery in one integrated system. It is widely used in riverbed alluvial gold, placer gold, and sand-gold separation projects across Africa, South America and Southeast Asia.
This combined equipment perfectly solves the problems of low recovery rate, incomplete screening and unstable operation of traditional single washing machines. The rotary trommel screen completes material classification and high-pressure washing, while the matched sluice box captures coarse and fine gold particles through gravity separation, greatly improving the final gold recovery efficiency.
2. Core Advantages
- Large Processing Capacity: Industrial heavy-duty design, stable hourly output from 50TPH to 300TPH, meeting formal mine batch production needs.
- High Gold Recovery Rate: Matched with professional gold washing carpet and multi-stage sluice box structure, it effectively captures fine gold and coarse placer gold.
- Complete Washing System: Equipped with high-pressure spray water system to break mud and clean raw sand, avoiding material blockage.
- Flexible Customization: Screen mesh size, sluice box quantity and overall configuration can be adjusted according to customer ore conditions.

4. Working Principle
Raw river sand ore is sent into the trommel drum through the feeding hopper. With the rotation of the drum and high-pressure water spraying, mud is fully broken and cleaned, and materials are classified through different screen holes. Qualified fine sand and gold-containing materials fall into the lower sluice box unit. Relying on water flow gravity separation, gold particles are settled and captured by the gold carpet inside the sluice box, while waste materials are discharged outward. The whole process realizes automatic feeding, washing, screening and gold recovery.
5. Application Scenarios
- River alluvial gold mining
- Riverbed sand gold washing and separation
- Large-scale placer gold mine production
- Mining projects with high mud content raw ore
