◉ PRODUCT SPECIFICATION



A dredger is a specialised engineering vessel designed for extracting sand and gravel from waterways such as rivers and lakes, primarily employed for the extraction, screening, and transportation of sand and gravel. Typically, a dredger comprises a hull, dredging apparatus, screening system, propulsion system, and conveying system. Based on operating principles and structural characteristics, dredgers can be categorised into various types including bucket dredgers, suction dredgers, and cutter suction dredgers.
The operational principle involves the excavation apparatus (such as chain buckets or suction pipes) lifting sand and gravel from the riverbed. This material is then separated from water via the screening system before being transported to designated locations through the conveying system. Sand dredgers offer high operational efficiency and are well-suited for large-scale sand and gravel extraction projects.
