On July 20, 2026, the 12-inch cutter suction dredger manufactured by Qingzhou Jinqi Mining Machinery, which has been in service for 8 years, completed assembly and operated smoothly at a reservoir dredging project in Hubei Province. This once again proves that the cutter suction dredgers produced by Jinqi boast reliable quality and outstanding durability after years of operation.

Waterway dredging plays a vital role in maintaining navigation channels, controlling sediment accumulation, improving port operations, and protecting aquatic environments. A cutter suction dredger is one of the most efficient solutions for removing hard soil, sand, clay, and other underwater materials.

An Amphibious Multipurpose Dredger is becoming an essential solution for challenging dredging environments where traditional equipment cannot operate efficiently. Combining floating capability, land mobility, and powerful excavation performance, this advanced machine helps industries improve productivity in river restoration, mining, environmental management, and waterway development.

On June 29, 2026 Beijing Time, Qingzhou Jinqi Mining Machinery Co., Ltd. completed the shipment of a 200TPH vibrating screen gold washing plant to our client in Kazakhstan.

​In today’s rapidly evolving dredging and mining industries, operators face increasing pressure to improve efficiency, reduce downtime, and handle more abrasive working environments than ever before. A Wear-Resistant Cutter Suction Dredger has become one of the most critical pieces of equipment in this context, especially for projects involving sand mining, river dredging, port maintenance, and coastal land reclamation.

​A 10-inch cutter suction dredger is one of the most widely used compact dredging solutions in small to medium-scale sediment removal projects. It combines cutting, suction, and hydraulic transport into a single integrated system, making it ideal for river maintenance, pond cleaning, coastal restoration, and mining tailings management. This article provides a comprehensive breakdown of how this equipment works, its core components, operational advantages, real-world applications, maintenance requirements, and selection considerations.
