Product Overview

The 12-inch jet-suction dredger boasts strong processing capacity, adapts to complex working conditions, and is widely used in waterway maintenance, lake dredging, and reclamation projects. It offers stable and reliable performance. The equipment relies on the jet principle: a high-pressure water pump generates high-pressure water flow, which is ejected at high speed through nozzles to create a negative pressure zone. This draws up sediment and mud from the bottom, mixing them with water into a slurry. Then, using vacuum suction and pressure differentials, the slurry is conveyed through a suction pipe to a designated location, achieving integrated excavation and transportation. With its advantages of large flow rate and high lift, this equipment can handle medium to long-distance transport and features a high degree of automation controlled by PLC. It can also be paired with mineral processing equipment to achieve integrated mining and selection, precisely meeting the core needs of large-scale dredging enterprises, mining companies, and land reclamation firms, effectively addressing pain points in large-scale engineering projects.

Working Principle

1. A high-pressure water pump delivers powerful energy, generating a high-flow, high-pressure water stream that is ejected at high speed through specialized nozzles, creating a stable negative pressure zone at the suction inlet. Leveraging the fluid dynamics of jet propulsion, it efficiently stirs various sediments and muds at the bottom, adapting well to complex geological conditions.

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

3. Equipped with a PLC-based automated control system, it allows precise adjustment of operational parameters, enabling intelligent integrated excavation and transportation 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 requirements such as placer gold mining.
