As one of the largest decanter centrifuge manufacturers, GN Solids Control has been provided thousands of decanter centrifuges for worldwide customers. GN decanter centrifuges are widely using in many solids and liquid separation area. GN Solids Control engineers have designed different models to suit for customers’ special demands for various work site usage. 

Several weeks ago, GN Solids Control delivered 2 sets 22 inch size rotating bowl decanter centrifuges and dosing units to one Singapore TBM customer. It well known that a large TBM usually needs a large water treatment plant. As part of the TBM operations, large quantities of water need to be input and also need to be removed from the TBM operation, back to the ground level surface. This water is typically mixed with fines from the operation behind the head of the TBM. The TBM produces wet spoils that get transported to access shaft via conveyor belts. 

For this TBM Slurry Treatment System, it mainly includes the following parts: 

1. GN Solids Control decanter centrifuge  

GN Solids Control manufactures 9 inch, 14 inch, 18 inch and 22 inch decanter centrifuges. Here are 2 sets 22 inch size decanter centrifuges GN provided as the treating volume demand is pretty large. Generally speaking, the more solids in the slurry, the smaller treating flow GN centrifuge can provide. After treated by GN centrifuge, those particles larger than 2~ 5 microns can be separated out, so treated slurry will be reused by TBM. 

2. GN Dosing Unit

Dosing unit helps those finer solids get together, so centrifuge will separate out more solids.  

3. GN Container

GN decanter centrifuge and GN Dosing Unit are both put in one standard container. The centrifuge feeding screw pump is also fixed inside the container. All treating equipment can be moved easily when the TBM move to work in different sites. 

GN Solids Control is especially good at providing turnkey solutions, welcome to connect with us for your special demands.
