A gold trommel wash plant is a rotating cylindrical sieve designed to separate gold-bearing gravels efficiently. Its modular design integrates scrubbing, screening, and concentration functions, making it ideal for placer mining operations.
1. Trommel Screen: A perforated rotating drum (typically 3–10m long, Ø1.5–3m) classifies materials by size.
2. Scrubbing System: High-pressure water jets break clay-bound aggregates.
3. Sluice Box/Sluice Matting: Captures gold particles via gravity separation.
4. Feed Hopper & Conveyor: Ensures steady material flow (capacity: 50–300 TPH).
| Parameter | Specification |

Q: What’s the optimal feed size?
A: ≤100mm for efficient screening and gold recovery.
Q: How to maintain trommel longevity?
A: Regularly inspect screen wear and bearing lubrication intervals (every 500 hours).
A Ghana-based operation deployed a 100 TPH trommel plant with Ø2m drum and rubber-lined sluice mats, achieving 92% gold recovery from alluvial deposits with <0.5mm gold particles. The system reduced manual panning labor by 70%.
For hard rock applications, pair the trommel with a jaw crusher or cone crusher upstream to pre-process ore. Downstream, centrifugal concentrators may enhance fine gold recovery (>325 mesh).
