High-Pressure Jet Suction Dredging Equipment from China Suppliers | Factory Direct, Customizable Solutions
Description
As a specialized piece of lightweight and high-performance dredging machinery, our Jet Suction Sand Dredger integrates the functions of sand extraction, transport, and dredging into one unit. It is purpose-built for sand mining, river dredging, and sludge removal projects worldwide.
Unlike traditional cutter suction dredgers, this model utilizes advanced jet suction technology. It features a cutter-less design that employs high-pressure water jets to agitate underwater sand and sediment, while a powerful suction pump simultaneously completes the extraction process. With a customizable daily output ranging from 300 to 8,000 cubic meters, it offers exceptional suction power that leaves no sand behind, making it highly effective in water depths from 0.3 to 12 meters.
Core Advantages
Constructed from high-grade anti-corrosion steel, the hull is designed to be lightweight, agile, and easy to maneuver.
It performs reliably in both freshwater environments (such as rivers and reservoirs) and saltwater conditions (including shallow seas), offering strong resistance to wind and impact. This versatility makes it ideal for small to medium-sized sand yards, riverways, and coastal regions. Additionally, it can be integrated with gold mining equipment to support auxiliary operations.
