The 200m³/h High Recovery Bucket Chain Dredger stands as a high-capacity solution for underwater alluvial gold mining, integrating diesel-powered dredging mechanics with a multi-stage gold recovery system to maximize yield in submerged environments. Engineered for 200m³/h throughput, it features a reinforced chain bucket ladder (with wear-resistant manganese steel buckets) that excavates sediments from riverbeds up to 20 meters deep, feeding directly into a trommel screen for initial classification of gravel and clay. Post-screening, material flows through an integrated gold centrifuge (with variable G-force control) and pulsating sluice box—a combination that ensures 90%+ recovery of gold particles, including micron-sized flakes often missed by conventional systems.
Multi-Stage Recovery System: Sequential processing through trommel screening (removes large debris), centrifugation (concentrates heavy particles), and pulsating sluice boxes (captures fine gold) ensures comprehensive particle capture.
Corrosion-Resistant Construction: All underwater components use 316 stainless steel, with bucket chains coated in wear-resistant alloy to withstand abrasive sediments and saltwater environments.
Intelligent Control System: Real-time monitoring of dredging depth, material flow rate, and gold concentration via digital display, with automatic adjustments to optimize recovery efficiency.
Low Maintenance Design: Quick-release bucket pins and modular screen panels reduce downtime—chain buckets and screens require replacement every 6-12 months under heavy use.
Riverbed Mining: Efficiently processes submerged alluvial deposits in major river systems, where gold accumulates in layers of gravel and sand.
Lake and Reservoir Operations: Handles large volumes of sediment with minimal environmental impact, thanks to low turbidity discharge technology.
Mining Contractors: Suitable for short-term projects requiring high throughput, such as seasonal gold rushes or site development for larger operations.
Q: Can it operate in fast-flowing rivers?
A: Yes, the hydraulic winch system with 4-point anchoring stabilizes the dredger in currents up to 2 m/s, maintaining consistent excavation depth.
Q: What’s the smallest gold particle recovered?
A: The pulsating sluice box, paired with 300-mesh matting, captures particles as small as 0.05 mm—ideal for fine flour gold recovery.
Q: How long does installation take?
A: On-site assembly takes 2-3 days with a 5-person crew, including pontoon inflation, mechanical setup, and system calibration.
