20 Inch Sand Cutter Suction Dredger Machine for Sand Mining and Land Reclamation Works

We use q355b marine-grade steel with high-strength anti-corrosion coating. All steel plates undergo shot blasting and multi-layer sealing to ensure 10-15 years of service life even in harsh salt-water environments.

Our dredgers utilize the venturi effect design, which increases suction efficiency by 20%-30% while reducing fuel consumption. Integrated with PLC intelligent control systems, operators can monitor performance in real-time, significantly lowering operational risks.

Absolutely. We provide customized solutions based on your project parameters, such as dredging depth, discharge distance, and soil type. Whether it's for a mining site in Africa or a canal project in SE Asia, we optimize the engine power and pipeline configuration for you.

Yes. Our factory is ISO9001 certified, and our products can be built to meet CCS, BV, ZC, and CE standards. We also provide full technical documentation for local customs clearance and safety inspections.

We use a modular design for all heavy equipment. Units are disassembled for standard container or flat rack shipping to minimize costs. Upon arrival, the modular sections are easily reassembled via high-strength bolts without onsite welding.
