GNLW454GT Mud Dewatering Centrifuge for Hydrovac Slurry Treatment

One set of GNLW454GT mud dewatering centrifuge package are ready for shipment to Hydrovac slurry treatment project.


GNLW454GT Decanter centrifuge technical specification is as below:
The bowl diameter is 450mm, the bowl length is 1890mm, the length/ diameter ratio is 4.2.The max bowl speed is 3452rpm, the max G force is up to 3000G. The main motor is 37KW / 45KW/ 55KW, the back drive motor is 11KW/ 15KW/ 22KW, the beach angle is 8.5 degree, The bowl main material is made of duplex stainless steel SS2205 by centrifugal casting, the screw material is made of duplex stainless steel SS2205, the screw is protected by tungsten carbide tiles, and the centrifuge is drived by positive pressurized VFD control panel with PLC touch screen and HMI interface. The bearing is premium SKF bearing for reliable and longer working life. The T series decanter centrifuge is mainly used for dewatering unit.


GN solids control design and manufacture waste management for hydrovac slurry treatment system. The working principal is to use solids liquid separation equipment to treat the slurry from vacuum truck of hydrovac project. The slurry is contaminant free which is from physical utility location in public right of ways, and directional drilling for replacement of underground pipes and construction.


A complete hydrovav slurry treatment system including waste catch hopper, coarse solids separation shaker with fluids catching tank, Fine mesh shaker , desilter and mud tank, dewatering decanter centrifuge and chemical dosing unit with centrifuge dewatering tank or telescopic skid. The decanter centrifuge and VFD control panel and feeding pump are all installed on the telescopic skid with fluids collection tank and a transfer pump.
Except for T series decanter centrifuge, GN also produce fully hydraulic drive decanter centrifuge, Y series separation decanter centrifuge, C series clarifying decanter centrifuge and three phase decanter centrifuge.
