Last week, GN Solids Control finished a mud decanter centrifuge dewatering system for a TBM engineering company in China. The decanter centrifuge dewatering unit will be used to treat waste slurry from TBM drilling.
big bowl decanter centrifuge
The decanter centrifuge used in the dewatering system is a special model with very huge bowl: GNLW764A-VFD. The bowl size of the centrifuge is 760mm (30 inch) . The bowl length is up to 3328mm. It is a high speed 2-phase decanter centrifuge for liquid and solids separation. The cut point of the centrifuge is 2 ~ 5 microns. It is a dual motor centrifuge. The main drive motor used in the decanter centrifuge is 160Kw, and back drive motor is 90kw.
The chemical dosing unit used in the centrifuge dewatering unit is a very big size GNDW-6000L. The chemical dosing capacity of the unit is 6000L per hour in order to suit the big bowl centrifuge handling capacity.
The GNLW764A-VFD 30 inch big bowl decanter centrifuge is fixed inside a 40ft container, there are windows and door with access to discharge soil by screw conveyors.The GNDW-6000L chemical dosing unit is fixing on another 40ft container and lies on the top of the centrifuge container. It can minimum the footprint to save space.
