        Cutter Suction Dredger

        A suction dredger is a specialized dredging equipment with a rotating cutter as its core excavation component. It integrates excavation, loosening, and suction and discharge functions. The core principle is to use the cutter to cut the soil and the mud pump to suck and discharge the mud under negative pressure, enabling continuous "excavation - transportation" operations. It is widely used in large-scale water-related projects such as waterway dredging, land reclamation by dredging, river channel cleaning, and port construction.

        Drilling Pump Dredger

        A drilling dredger is a specialized dredging equipment that integrates drilling, crushing, excavation, and suction and discharge functions. Its core consists of a drilling tool that penetrates hard soil or rock layers. It is combined with a crushing mechanism to break down hard soil masses, and then the excavated materials are transported to the designated area through the suction and discharge system, enabling precise dredging operations on deep and hard soil conditions.

        Jet Suction Dredger

        The jet suction dredger is a vessel that integrates the functions of impact, stirring, suction of sediment, and transportation. Its core mechanism is that a high-pressure water pump generates a high-pressure water flow to impact the bottom sediment, making it moist and disintegrate into slurry. Subsequently, through negative pressure, the slurry is sucked into the designated area by the suction pump, thereby enabling the dredging and silt removal operation in shallow water areas.

        Suction Dredger

        A suction dredger is a specialized sand extraction equipment that operates based on the core principle of "rotary cutting + suction + transportation". It integrates excavation, crushing, and suction and discharge functions. The core mechanism involves using a rotating cutter to cut the underwater sediment (or hard soil layer), combined with a negative pressure suction pump to form a slurry, and then transporting the slurry over long distances through pipelines to the designated area, achieving integrated continuous operations of sand extraction and dredging.

    The Jet Suction Sand Dredger from Duohui represents a paradigm shift in lightweight dredging efficiency. It is a multifunctional mining platform that seamlessly integrates suction, transport, and dredging operations, purpose-built for global applications such as sand extraction, river desilting, and sludge management.
    The key differentiator lies in its cutter-free jet suction mechanism. Instead of mechanical agitation, it relies on focused high-pressure water jets to loosen and suspend bottom sediments. A high-power suction pump then lifts the slurry in a continuous, residue-free operation. This method delivers powerful suction with no dead zones. With a flexible daily output of 300 to 8,000 cubic meters, the dredger adapts to varying project scales and water depths ranging from 0.3 to 12 meters.
