Mud Cleaning System.DESCRIPTION
-
An efficient TBM slurry separation plant is the basis for the successful use of slurry-supported tunnel boring machines(TBM). The GN Slurry separation plant is popular for project of AVN Machines , Mix shields or Shaft Sinking Machines . GN Solids Control utilize our shale shakers, desander, desilter, as well as decanter centrifuges to processes separate and remove the excavated solids from the bentonite suspension – a mixture of water and thixotropic clay. The cleaned fluid is then transferred back to the slurry circulation.
TBM Slurry Separation Plant size available:
Small Size:GNTBM-120B (120m³/h), GNTBM-260B (260m³/h),GNTBM-360B (360m³/h), GNTBM-500B( 500m³/h)
Big Size:GNTBM-1000B( 1000m³/h), GNTBM-1500B(1500m³/h), GNTBM-2000B (2000m³/h), GNTBM-2500B (2500m³/h), GNTBM-3000B (3000m³/h)
TBM Dewatering Decanter Centrifuge
GN Manufacture different size of decanter centrifuge for TBM slurry dewatering treatment. The 22 inch GNLW553C-VFD and the 30inch GNLW764A big bowl decanter centrifuge are popular for the TBM mud treatment. GN provides the dewatering centrifuge together with chemical dosing unit as a full package to customer. The dewatering centrifuge package can be containerized for easy movement as below:

Process of TBM Slurry Separation Plant
- A coarse shale shaker will remove big particles from the TBM Slurry.
- A centrifugal pump will bake the slurry and feed to coarse hydrocyclones.
- A dewatering shaker below the coarse hydro cyclones will drying the solids.
- The other centrifugal pump will pump the slurry to fine hydrocyclones for separation of solids above 20 microns.
- The fine shaker dewatering the solids discharge discharged from the fine hydrocyclones.
- Decanter centrifuge will separate solids above 2-5 microns without chemical.
- And the chemically enhanced decanter centrifuge will separate solids above 1 micron.
