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 OilFieldScreens Slurry separation plant is popular for project of AVN Machines , Mix shields  or Shaft Sinking Machines . OilFieldScreens 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.

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.
