GN Released Updated TBM Slurry Separation Plant

on . Posted in News

What is a TBM Slurry Separation Plant?
 
TBM slurry separation plant is to separate and remove the excavated solids from the bentonite suspension - a mixture of water and thixotropic clay. The cleaned liquid is then returned to the slurry circulation.

GN Solids Control uses shale shaker, desander, desilter and decanter centrifuge to form the TBM slurry separation plant. An efficient TBM slurry separation plant is the basis for the successful use of sludge-assisted tunnel boring machines (TBM). 
The GN Slurry Separation Plant is popular for projects by AVN Machines, Mix Shields or Shaft Sinking Machines. With 12 years development, GN has made great progress in this field and an updated TBM Slurry Separation Plant has been released recently.
 
Available Models of GN TBM Slurry Separation Plant 
 
Standardized mud-water separation system, including:
1.GNTBM-240M, capacity:240m3/h 
2.GNTBM-360M, capacity:360m3/h
3.GNTBM-500M, capacity:500m3/h
4.GNTBM-1000M, capacity:1000m3/h
Larger capacity systems can also be designed for customers requirement.
 
In addition, GN can also provide a shield dewatering centrifuge:TBM dewatering decanter centrifuge

TBM slurry separation plant process
1.A coarse slate shaker removes large particles from the TBM slurry.
2.A centrifugal pump bakes the slurry and conveys coarse hydrocyclones.
3.A dewatering shaker below the coarse hydrocyclones dries the solids.
4.The other centrifugal pump pumps the slurry into fine hydrocyclones to separate solids over 20 microns.
5.The fine shaker dewaters the solids released from the fine hydrocyclones.
6.Decanter centrifuge separates solids over 2-5 microns without chemicals.
7.The chemically improved decanter centrifuge separates solids over 1 micron.
