The trenchless mud purification system s a necessary equipment of foundation construction,used for slurry purfication recycling that adopting slurry hole wall supporting and cutting away construction,with the features of reducing construction cost ,increasing construction efficiency.

The horizontal directional crossing (HDD) mud purification system purifies the solid particles in the mud. The solid control equipment is used to remove the harmful solids in the mud and retain the useful solids, so as to meet the requirements of the crossing process on the mud performance. The harmful solid phase in the horizontal directional crossing mud mainly refers to the drilling cuttings that wear the equipment and affect the rheological properties of the mud.

Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.

Desander is 2nd solids control equipment of the drilling mud solids control system. It is used to separate particle sized 47~76 micron . RuiLin desander is widely used in oil and gas drilling filed,HDD,slurry separation,ec. industries.

RLCNQ series desilter is 3rd phase equipments in solids control system. Desilter cone including 4 inch and 5 inch mainly separate 12~47 micron particles.

 RuiLin's Shearing pump is one kind of centrifugal pump.  The type is overhead belt drive.
