TBM Slurry Separation Plant

TBM Slurry Separation Plant

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 Dewatering Decanter Centrifuge

P3 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:

Features of GN Tunneling Slurry Separation Plant

Process of TBM Slurry Separation Plant

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