TBM is short for Tunnel Boring Machine. It is also known as a “mole”. It is a construction field drilling machine used to excavate tunnels and micro-tunneling with a circular cross section through a variety of soil and rock strata. They can bore through anything from hard rock to sand. Tunnel diameters can range from 1 m to 17.6 m to date. For smaller diameter less than 1m, it is HDD and CBM drilling. The most important part of a tunnel boring machine is its cutter head. Tunnel boring machine (TBM) is widely used today due to their ability to construct tunnels at record speeds.

But as the big diameter of the tunnel, the TBM drilling will generate large quantity waste slurry (mixture of rocks, sand, soil, water and drilling mud). The waste slurry must be treated to recover and reuse water, and reduce the solids phase waste. GN Solids Control makes different sizes of TBM Slurry Separation Plant to cater for different diameter tunneling excavation activities.

GN Solids Control is specialized in full line drilling mud solids control. equipment. All the processing equipment used for TBM Slurry Separation Plant are designed and made by GN Solids Control: the coarse separation shale shaker, desander separator, desilter separator. GN Solids Control is also capacity to make dewatering centrifuge for TBM slurry separation plant form normal size centrifuge to the big bowl and big capacity size.

Below is the popular treating capacity of GN made TBM Slurry Separation Plant models.
1. TBM Slurry Separation Plant model: GNTBM-240M. The treating capacity is 240m3/h.
2. TBM Slurry Separation Plant model: GNTBM-360M. The treating capacity is 360m3/h
3. TBM Slurry Separation Plant model: GNTBM-500M. The treating capacity is 500m3/h
4. TBM Slurry Separation Plant model: GNTBM-1000M. The treating capacity is 1000m3/h

GN Solids Control can also make big capacity TBM slurry separation system: GNTBM-900M (900m³/h), GNTBM-1200M (1200m³/h), GNTBM-1400M (1400m³/h), GNTBM-2000M (2000m³/h), GNTBM-2800M (2800m³/h), GNTBM-3600M (3600m³/h)
