TBM and Bored Pile Desanding Plant

TBM and Bored Pile Desanding Plant

Mud Cleaning System.


GN Desanding Plant is the economic way for the mud recycling, it is popular for Bored Pile Slurry desanding plant, TBM slurry treatment, HDD (trenchless) as well as water well drilling etc.

GN Desanding Plant Working Principle

desander working Principle

The slurry pump sucks the mud from the mud pit, than enter into bottom layer screen of shale shaker (3) through buffer box(2), the coarse particles will be separated out and the mud flow to mud storage tank (4) through the bottom layer screen of shale shaker(3). The centrifugal pump (5) takes mud from the recycling tank(4), and feed to desander cone (6) with pressure for centrifugal separation, the  solids/sand  was discharged to upper shaker(3) from the outlet nipple of the desander cone. After dewatering process of the upper shaker(3), the fine solids was separated out. The mud passed the upper shaker screen returns back to recycling tank(4),the clean mud entered into intermediary tank(7) through desander cone overflow pipe. The mud in the intermediary tank (7) will go out through outlet pipe (9) or go back to recycling tank (4) depends on the fluid level in the recycling tank.
In the mud circulation process, there is a fluids level float switch (8) between intermediary tank (7) and recycling tank (4), it can balance the fluids level in the recycling tank(4). When mud level is low in the recycling tank (4) the overflow from the desander will enter recycling tank (4) through the intermediary tank (7). When the mud level is too high in the recycling tank (4), the mud will overflow to the intermediary tank (7) and go out from the outlet pipe (9). If operators want to get high quality clean fluids, the feeding capacity to the system can be reduced, and the repeat cleaning process will to get the result.

GN TBM Slurry Treatment Desanding Plant

As GN Manufacture shale shakers, desanders, desilters, decanter centrifuges. So GN Solids Control is able to provide complete solutions for TBM slurry treatment project.

The shale shaker for separation coarse solids, the desander for separation sands, the desilter for separation silts, the mechanical centrifuge for separation fine solids.The chemically enhanced technology with decanter centrifuge for separation ultra fine solids to discharge water.
