6-inch 150-type cutter suction dredger
General Description
Sand mining dredger is designed and manufactured with optimized hydrodynamics technology for sand suction and silt clearing. This kind of sand mining dredger is driven by electric motor. The sand mining dredger is suitable for conveying liquid with solid particles including sand, gravel, cinders and tailing etc. The sand mining dredger is mainly used in river, lake sand dredging, metallurgical industry, mining and thermal power plant, etc. It’s wear resistant wet parts are made of hard metal (Chrome alloy). The bearing assembly is composed of large diameter shaft and short overhang, so the sand mining dredger will have long-term bearing life. Sand mining dredger has the characteristics of high efficiency, energy saving, simple operation and easy management.
Main feature
1.Heavy duty, reliable and robust dredge body design and construction.
2.Specially designed dredger pump, suction reamer head and motor to realize high dredger suction ratio and more thorough dredging.
3.Best wear-resisting.Good wear-resisting property and big flow passage way that make the dredger pump suitable for mud, sand, big solid particles, ore pulp, coal pulp and coarse sand dredging.
4.Triple protection. Flexible sensors to realize over-heating protection, water-intake inspect protection and oil chamber protection to ensure long and safe pump operation under abominable working conditions.
5.Especially for multifunctional small and medium scale dredging projects
6.High-chromium alloy material, aluminum alloy, stainless steel pump material available for different work site situation.
7.One pump could add 3 pieces of extra agitator for higher work efficiency.
8.Hydraulic system pump available.
