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 has more than 10 years of experience in the design and manufacture of mud recovery systems, especially in trenchless projects with multi-function and compact design to cater for different demands and applications from clients. According to the different requirements from users, and jobsite situations, GN Solid Control can provides different configurations of mud recovery system and desanding plant to meet the requirements of different working conditions. There are usually two types of mud purification systems suitable for trenchless construction: one is sand removal unit with cyclone purification system, we usually call it desanding plant. And the other type of design is self-contained mud recovery system.

The desanding plant with hydro cyclone purification system occupies a small footprint, and is economical and affordable. The system is composed of a hydrocyclone and a double deck shale shaker, both of which are installed on a small mud tank. The sand removal cyclone purification system is a two-stage separation device, and its function is to remove coarse particles from drilling mud. The desanding plant is mainly used in projects that can accept larger particle size solid drilling mud, such as Microtunnelling, piling, and so on.

The high standard self-contained mud recovery system developed by GN Solid Control is composed of four stage separations: shale shaker for coarse cuttings separation, 10 inch desander cone separation, 4 inch desilter cone separation, and decanter centrifuge for ultra-fine solid separation. The mud tank of the self-contained mud recovery system has a bigger storage volume to store the purified drilling mud. At the same time, it also has more tank surface space to arrange more separation equipment. Customer can also choose a centrifuge to reduce the ultra-fine solid in the drilling mud and to avoid the enrichment of the ultra-fine solid phase in the drilling mud.

GN Solid Control not only has a standard sizes of mud recycling system and desanding plant, but also provides custom-designed mud recovery system to meet for different demands.

One set 500GPM drilling mud recycling system was sent to Middle East for water well drilling. Besides the drilling mud recycling system for oil drilling, they also need drill water well for daily requirement for clean water. For the person living in Middle East, water is more important than oil. Sounds like a joke, but this is reality.
Water well is not so deep like the oil well, and the drilling cost is also very cheap comparing with oil drilling. However, both this 2 drilling processes need the drilling mud recycling system to speed up the drilling process and protect the drill bit. Water well drilling may not need the used drilling mud to be separated very clean as it is not requested strictly. Just like this 500GPM unit shipped to Middle East, it is a very compact
model, while it has all the necessary separation equipment.
