Product Overview

The 12-inch jet-suction dredger boasts strong processing capacity and adapts to complex operating conditions, making it widely used in waterway maintenance, lake dredging, and land reclamation projects. Its performance is stable and reliable. The equipment relies on the jet principle: a high-pressure water pump generates a high-pressure water flow that is rapidly ejected through nozzles, creating a negative pressure zone. This draws seabed sediment and sludge into a slurry, which is then conveyed to a designated location via suction pipes using vacuum suction and pressure differentials, achieving integrated excavation and transport operations. With its advantages of large flow rate and high lift, this equipment is suitable for medium- to long-distance conveyance and features a high degree of automation controlled by PLC. It can be paired with mineral processing equipment to achieve integrated mining and selection, precisely meeting the core needs of large-scale dredging enterprises, mineral development companies, and land reclamation project firms, effectively addressing the pain points of large-scale engineering projects.

Working Principle

1. A high-pressure water pump delivers powerful output, generating a high-flow, high-pressure water stream that is rapidly ejected through a dedicated nozzle, forming a stable negative pressure zone at the suction inlet. Leveraging the fluid dynamics of jet propulsion, it efficiently stirs various sediments and sludge on the seabed, adapting to complex geological conditions;

2. The combined action of negative pressure suction and pressure differential thoroughly mixes sediment and sludge with water to form a uniform slurry. Thanks to its design featuring large flow and high lift, it enables stable medium- to long-distance conveyance without requiring additional boosting equipment;

3. Equipped with a PLC automated control system, it allows precise adjustment of operational parameters, enabling intelligent integrated excavation and transport operations, reducing manual intervention, and enhancing both precision and efficiency;

4. It can be flexibly paired with mineral processing equipment to simultaneously carry out sediment extraction and screening, achieving integrated mining and selection, expanding operational capabilities, and accommodating diverse engineering needs such as placer gold mining.
