Recently, One unit of desander unit and decanter centrifuge unit are ready for shipment for construction mud treatment to overseas company. The technical configuration is as below:
The desander unit model is GNMS-1000D, it includes a double deck shale shaker with desander cones, centrifugal pumps, mud tank, tank accessories. It is an ideal compact design desander unit for bored pilings, TBM, HDD trenchless engineering and other construction works, the treating capacity is 1000gpm. After treatment, the clean mud will flow back to drilling machine for reuse or it can be used to prepare for new drilling fluids with mixing hopper and mixing pump. You can use GN produced jet mud mixer unit ( mixing hopper, mixing pump, pipelines, electric control panel on one skid as a complete mixing unit to contact with client’s own storage tank.The separation cut point is 40 microns. If you need to separate fine solids, the desander unit will be re-designed with desilter hydrocyclones, with separation cut point 20 microns. After treated by desilter cone, the clean fluids can be reused for construction, the purpose is to reduce water consumption, reduce construction waste, to meet environmental protection regulation of local government. After long time operation, more and more fine solids smaller than 20 microns accumulated in the mud, which can not be reused, then we will need to use decanter centrifuge unit, which with separation cut point 5 microns. And after the project is finished, it is required to separate the water from solids for final disposal, water will be disposal to river, and the solids for landfill or other construction works.
The decanter centrifuge unit model is GNLW224FT-VFD, the max G force is up to 3077G, and max speed is up to 5000rpm. Working with chemical dosing unit, the construction water will be clean for disposal.
