One set of Dredging slurry dewatering equipments working in North America, here is the working video for your reference. https://www.gnseparation.com/video/dredging-slurry-dewatering-equipment-working-in-north-america
It is a customized design slurry dewatering system according to our client’s requirement, if you need a solution for any kinds of slurry in solids liquid separation, for example, dredging slurry, mining tailings, industrial waste slurry, animal waste, oil sludge, drilling waste, etc., pls contact with GN solids control/ GN separation.

Mainly the dredging slurry dewatering equipments including shale shaker ( to separate coarse solids and reduce solids content) , desander ( solids separation cut point 40 microns), desilter ( solids separation cut point 20 microns), big bowl dewatering centrifuge ( mechanical separation cut point 2~5 microns, working with chemical dosing to improve the separation efficiency), feeding pump, screw conveyor ( to transfer the discharged solids), mud tank for liquids storage, with pipelines for proper flow diagram. The working process is as below:

Firstly the shale shaker separate the coarse solids bigger than 300 microns by using proper mesh size shaker screen, secondly the desander cone to separate the 50~300 microns solids, the desilter cone to separate the 20~ 50 microns material, the dewatering centrifuge to separate fine solids to get clean water, which can be sent to waste water treatment facility if need. The solids can be transferred by screw conveyor to cuttings collection box and transfer to other area for construction area. The whole system meets the standard of North America usage.

The big bowl dewatering centrifuge is 30 inch bowl diameter, the bowl length is 131 inch, the designed capacity is 528gpm, the max G force is up to 3000G, the gearbox torch is 25000N.M., gearbox ratio is 38:1. The main motor is 160KW, the back drive motor is 90KW, the centrifuge is drived by the VFD control panel.
