GN TBM Slurry separation equipment are optimally adapted to the requirements of the tunnelling (TBM) process and separate the drilling suspension completely from the solid particles consisting of gravel, stone and sand in various grain sizes. A powerful combination different solids control equipment of state-of-the-art shale shaker technology and Hydro cyclones with high g-forces results in deposit able excavated material.
GN Solids control manufacture all major solids control equipment for the TBM Slurry separation system including following:
- TBM Slurry separation Shale Shakers for coarse solids separation.
- TBM Slurry separation desander and desilters for desanding and desilting separation.
- Big bowl big volume decanting centrifuge for fine solids separation.
- Centrifugal slurry pump for feeding to the separation equipment.
- Mixing hoppers for bentonite mud mixing.
- Mud tanks for storage drilling mud
One strength of slurry shields (TBM) is their versatility when used in heterogeneous ground conditions. The shale shaker elements must be adjusted in the separation plant if the soil and rock conditions vary. he use of durable long life polyurethane desander and desilter or steel screens also has a very positive effect on the cost effectiveness and efficiency of the entire solids control separation process.
