Mud Recycling Unit for overseas Trenchless Projects

Recently several sets of mud recycling system are ready for shipment to overseas trenchless projects.


The trenchless mud recycling system is a specialized equipment setup used in horizontal directional drilling (HDD) and other trenchless technologies. Its primary function is to clean drilling fluids (commonly known as mud) during the drilling process. The purpose is to use the trenchless mud recycling system is that the recycling drilling fluids can be used to lubricate the drill bit, stabilize the borehole, and carry cuttings back to the surface. These fluids need to be constantly circulated and maintained to ensure efficient drilling and environmental compliance.


Environmental Benefits: Recycling systems help minimize waste and reduce the environmental impact of HDD operations by reusing drilling fluids.
Operational Efficiency: By continuously recycling and maintaining drilling fluids, these systems contribute to the efficiency of trenchless drilling operations, reducing downtime associated with replacing fluids and improving overall productivity.
The basic configuration of a mud recycling system is consists of primary shale shaker, mud cleaner, feeding pump, centrifugal pump, mud agitator, decanter centrifuge, mud tank, etc.


The compact design mud cleaning unit consists of double deck shale shaker with hydrocyclones, the bottom layer shaker screen works as primary shale shaker to separate coarse solids from the drilling mud, the clean fluids dropped into the intermediate tank, the feeding pump feed the mud to hydrocyclones for second phase cleaning, the top layer shaker screen as mud cleaning drying screen to recycle more fluids. The clean fluids flow to client’s storage tank or mixing tank to prepare for new drilling fluids.
The hydrocyclone size is for optional for different applications, for TBM and Pilings, 10 inch, 12 inch or 20 inch can be selected; for HDD applications, 10 inch, 4 inch can be used. For more information, pls contact with GN solids sales.
