DK650 Cutter Suction Dredger

From its CCSB hull to the 2100mm reinforced cutter head, every centimeter of the DK650 Cutter Suction Dredger is optimized for non-stop, high-yield production in deep-water terrains.

1. Extreme Deep-Water Reach

The DK650 isn't just large; it’s deep. Featuring an extended ladder design, it achieves a 17.5m maximum dredging depth. Equipped with a 2100mm diameter alloy steel cutter and a 500kW dedicated motor, it can fracture high-density riverbeds and mineral-rich strata that smaller vessels simply cannot touch.

2. Advanced Power Management & Frequency Control

We integrated a 500kW variable frequency starting cabinet and an 800kW Yuchai generator group. This allows for precise control over the hydraulic and electrical systems, ensuring smooth start-ups, reduced mechanical stress, and significantly lower energy consumption during long-cycle operations.

3. High-Velocity 700mm Suction System

Efficiency starts with the intake. The 700mm suction / 650mm discharge pipeline system minimizes friction loss. Driven by the 2014kW Cummins core, the DK650 maintains a steady 70-meter head, allowing for efficient transport of high-concentration mineral sands up to 1000m and soft slurry up to 2000m+.

4. Industrial-Grade Stability & Maneuverability

With an 8.06m breadth and dual 23m length spuds, the DK650 provides a rock-solid platform. The integrated 4m stroke spud carriage system and heavy-duty 200KN winches allow for continuous dredging cycles, maximizing uptime in challenging waterway conditions.

DK650 Core Performance Indicators

FAQ

Q1: What are the benefits of using CCSB steel for the DK650 Cutter Suction Dredger hull?

A: CCSB steel is a high-tensile marine-grade material. It provides superior resistance to corrosion and structural fatigue. For a vessel of the DK650's scale, this ensures a service life of 20+ years even in abrasive and high-impact dredging environments.

Q2: How does the 500kW variable frequency system help my project's bottom line?

A: Standard direct-start systems create massive power surges and mechanical wear. Our Frequency Control Cabinet allows the cutter and pumps to accelerate smoothly. This reduces peak power demand, lowers fuel consumption by the generator, and extends the lifespan of the hydraulic pumps and gearboxes.

Q3: Is the DK650 Cutter Suction Dredger modular enough for international transportation?

A: Yes. Despite its size, the DK650 is built using a sophisticated modular pontoon system. Each section is engineered to be transported via heavy-lift bulk carriers or specialized flat-rack logistics, followed by professional on-site assembly by Dingke dredger's Elite Technical Team.

Q4: Can the DK650 be customized for specific mineral mining?

A: Absolutely. While the standard setup is for high-volume desilting, we can customize the 2100mm cutter head teeth and the 550WN pump’s internal alloy components to handle high-abrasion ores, ensuring maximum mineral recovery rates.
