This technical article provides a standard-compliant interpretation of chain bucket dredgers developed by Qingzhou Yakai Dredging Machinery Manufacturing Co., Ltd. With 26 years of R&D and industrial application experience in dredging and mineral processing equipment, we are a global leading supplier committed to driving industry technological advancement. Our chain bucket dredgers are tailored for dredging engineering, resource development, and engineering service sectors, effectively addressing pain points such as poor complex condition adaptability, low operational efficiency, and high maintenance costs. Strictly adhering to ISO 9001, CCS, and BV international standards, our products achieve core breakthroughs in intelligent control systems and integrated dredging-mineral processing operations. To date, our technologies have been applied in over 80 countries and regions, serving numerous enterprise clients, and have been performance-verified in river dredging, port construction, and sand gold mining scenarios, holding CCS and BV certifications for high reliability.

A chain bucket dredger is specialized waterborne engineering equipment that uses rotating bucket chains to excavate underwater sediment, ore, or other materials, integrating hydraulic transportation and gravity separation functions based on mechanical excavation and gravity separation principles. It enables efficient dredging and resource recovery, becoming an indispensable technical support for waterway management, port construction, and resource development.
Main Classifications
To meet diverse industry and working condition needs, our dredgers cover two core series, with customizable solutions for special scenarios:
Standard Series (4-inch to 26-inch): High-stability models for conventional river dredging, port construction, and sand mining, featuring reliable operation and standardized production.
Custom Series: Tailor-made models for complex scenarios like mountain rivers, with modular structure and intelligent adaptive systems.
Design Philosophy
Our products follow core concepts of high reliability, customization, and energy efficiency. Fully considering harsh industrial conditions, we adhere to full-life-cycle reliability standards to provide stable, low-maintenance, cost-effective solutions.
Our chain bucket dredgers operate on mechanical excavation, hydraulic transportation, and gravity separation technology, with a three-step implementation logic:
1. Excavation: Rotating chain buckets grab underwater sediment or ore, adapting to different water depths and geological conditions.
2. Transportation: High-flow pumps with optimized channels transport materials to on-board separation modules.
3. Separation: Integrated gravity separation technologies (jigging, shaking table) extract target minerals like sand gold, with tailings discharged or recycled.
Core innovations include PLC-based intelligent control (real-time condition monitoring, auto parameter adjustment) and integrated dredging-separation modules. Compared to traditional single-function dredgers, our equipment improves operational efficiency by 15-20% and reduces fuel consumption by about 10%.
