1.Description of Bucket Chain Diamond Dredger
The bucket-chain gold and diamond dredger is a specialized floating vessel designed for the extraction of placer gold and diamonds from underwater deposits. Its key features can be summarized as follows:
Integrated Working Process:
The vessel functions as a self-contained floating platform integrating excavation, screening, and mineral processing. It employs a front-mounted continuous bucket-chain system to excavate ore-bearing sand and gravel from the underwater bed. The material is then fed into a rotating trommel screen for washing and size classification. Subsequently, gravity separation devices - such as sluice boxes and jigging machines - efficiently recover heavy concentrates including gold particles and diamonds.
High Recovery Efficiency:
The system achieves exceptional recovery rates across various particle sizes, particularly for fine-grained materials. For gold particles ranging from 0.02-0.5 mm, recovery rates can exceed 90%. The configuration can be optimized specifically for diamond recovery through specialized sorting modules.
Operational Adaptability:
Featuring an adjustable hull draft, the vessel can operate in diverse water depth conditions. Its modular design facilitates maintenance and replacement of wear components while allowing configuration adjustments for different mining conditions.
Typical Applications:
Placer gold and diamond mining in rivers, streams and waterways
Shallow offshore and lacustrine mining operations
Retreatment of historical tailings and previously worked mining areas

3.Advantage of Bucket Chain Diamond Dredger
Integrated Workflow:
This gold diamond bucket chain dregder is typically a floating platform that integrates excavation, screening, and mineral processing. It uses a front-mounted bucket-chain system to extract ore sand from the waterbed, which then passes through a trommel screen for screening and washing. Finally, gravity separation equipment such as sluices and jigs is used to isolate gold particles.
Outstanding Recovery Rate:
The gold diamond bucket chain dredger achieves excellent recovery efficiency for gold particles of varying sizes, particularly for fine-grained gold (0.02-0.5mm), with a recovery rate of over 90%.
Strong Adaptability:
The gold diamond bucket chain dredger's draft is adjustable, enabling it to adapt to different water depth conditions. Additionally, its modular design facilitates maintenance and the replacement of wear-prone parts.
