A gold mining trommel with a processing capacity of 200 yards per hour is a high-efficiency screening solution designed for large-scale placer mining operations. This equipment separates gold-bearing gravel from waste material through a rotating drum with screen panels, ensuring optimal recovery rates.
– Capacity: 200 cubic yards/hour (150 m³/h)
– Drum Diameter: 5–8 ft (1.5–2.4 m)
– Drum Length: 10–20 ft (3–6 m)
– Screen Mesh: Adjustable (typically 1/2″ to 1″)
– Power: 30–75 HP diesel or electric motor
– Material: High-carbon steel or abrasion-resistant rubber lining
For hard rock gold ore, a complete crushing and screening line may include:
1. Primary Jaw Crusher (e.g., 400×600 mm feed opening)
2. Secondary Cone Crusher (e.g., GP300 for finer crushing)
3. Trommel Screen (200 yd³/h capacity)
4. Slurry Pumps & Gravity Concentrators (for gold extraction)
Q: What’s the lifespan of trommel screen panels?
A: Typically 6–12 months, depending on abrasiveness of feed material.
Q: Can this trommel handle clay-rich material?
A: Yes, but a pre-scrubbing system is recommended to break up clay clumps.
A project in Alaska utilized a 200 yd³/h trommel paired with a jaw crusher and shaking tables, achieving a gold recovery rate of 92%. The system processed alluvial deposits with minimal water consumption due to closed-loop water recycling.
For customized configurations, consult equipment manufacturers to match your ore characteristics and production goals.
