​The Small Shallow-Water Cutter Suction Dredger has become one of the most practical and cost-efficient solutions for modern dredging operations in rivers, lakes, ponds, and coastal shallow zones. This article explores its working principles, technical advantages, application scenarios, maintenance requirements, and selection guidance. It is designed to help project owners, contractors, and engineering companies understand how this equipment solves common dredging challenges such as low water depth, sediment blockage, limited accessibility, and operational efficiency.

On June 9, 2026, Qingzhou Jinqi Mining Machinery Co., Ltd. officially launched a special purchase and sales service for used gold mining equipment previously sold by our company.

​Gold mining operations often face one major challenge: clay-bound ore and muddy materials that reduce recovery efficiency and increase processing costs. A Gold Trommel Scrubber is specifically designed to break down compacted materials, remove clay contamination, and prepare ore for downstream recovery systems.

On May 25, 2026, Qingzhou Jinqi Mining Machinery completed loading and shipment of the placer gold processing equipment set bound for Namibia.The consignment is shipped in three ocean-going containers, consisting mainly of rotary drum washers, Nelson centrifugal concentrators, hydraulic pulsating sluices, fixed sluices, diesel generator sets and high-pressure water pump assemblies.

Gold mining operations constantly face challenges such as fine gold loss, high water consumption, poor recovery efficiency, and increasing operational costs. An Alluvial Gold Pulsating Sluice is designed to overcome these issues by combining gravity concentration principles with pulsating water flow technology.
