Qingzhou Yongli Mining and Dredging Machinery Co., Ltd. products

The dredger could be divided into bucket type and pump suction type. Bucket type dredger is applied for waterways with high percentage of clay and gravels, while pump suction type can only be used for terrains with low percentage of clay and gravel. Customized according to specific requirements for dredging depth and capacity. Iron ore needs to be retrieved first with magnetic separator if the percentage is high in the raw ore, then gold, diamond, zirconium will be concentrated.  The dredger is composed of several gravity concentrators. The concentration ratio could reach as high as 1:1000, and the recovery efficiency about 90% after series of separator.

Could be used to mine gold mixed with sand in palaeochannel, palaeo-riverbed, alluvial placer, tailing after ball milling, and diamond and zirconium in raw ore.

Working principle: Bucket rotate around the underwater dredging wheel, scooping up the solid in the riverbed, then trommel classifier, with single layer or double layer screens, will separate the gravels, clay balls, water plants with need sand.
