01. Product Overview 

Maximize your alluvial gold recovery with our complete Rotary Drum Gold Washing Production Line, an integrated processing system engineered for high-capacity clay breakdown, screening, and fine gold concentration. This turnkey solution combines a heavy-duty rotating scrubber trommel, high-pressure washing system, and optional recovery modules to deliver exceptional gold capture from even the most challenging clay-bound deposits. Ideal for medium-to-large scale placer mining operations, this production line provides a continuous, efficient processing circuit that maximizes your return on investment. By offering a complete, pre-engineered washing and recovery system, we help you achieve consistent gold production with minimal setup time and operational complexity.

02. Key Features & Unique Selling Points 

- Aggressive Clay Disintegration:The heavy-duty rotating drum with internal lifters and high-pressure spray bars creates intense tumbling and scouring action that thoroughly breaks down clay, cemented gravel, and conglomerates. This aggressive liberation ensures that even the finest gold particles are released and available for recovery, dramatically improving overall yield.
- High-Capacity Continuous Processing: Engineered for large-volume throughput, this production line handles feed rates from 20 to over 200 tons per hour. The continuous process flow from feed hopper to final concentrate ensures uninterrupted production, maximizing your daily gold output and operational efficiency.
- Complete Integrated System: From feed hopper and vibrating grizzly to trommel scrubber, screening section, and centrifugal concentrators or sluice boxes, this production line provides all necessary components in a single, coordinated flow sheet. This simplifies procurement, installation, and operation, reducing the complexity of building a processing plant from multiple suppliers.
- Adjustable Screening & Recovery Configuration: The modular design allows you to customize screen mesh sizes, select different concentrator types, and adjust water flow rates to match your specific deposit characteristics. This flexibility ensures optimum performance for varying feed conditions, maximizing recovery across different mining areas.
- Water-Efficient & Environmentally Conscious:Our production line incorporates water recirculation systems and efficient spray bar design to minimize fresh water consumption. Settling ponds or thickener options allow for responsible tailings management, helping you meet environmental regulations while reducing operational costs.
