GN Trenchless Mud Recycling Systems for Overseas Engineering Company

As global infrastructure development accelerates, trenchless technology and tunnel boring machine (TBM) operations have become indispensable for constructing pipelines, utility networks, and underground transit systems with minimal surface disruption. A critical factor determining the success, cost efficiency, and environmental compliance of these projects is effective drilling fluid and slurry management. GN Solids Control, a professional manufacturer of solids control equipments and customized mud tank system, has established a strong international presence by delivering customized trenchless mud recycling systems and TBM slurry separation plants to overseas engineering companies all of the world.


GN trenchless mud recycling systems are engineered to recover and reuse drilling fluids (typically bentonite mud) in horizontal directional drilling (HDD), pipe jacking, and piling operations. These systems reduce waste disposal costs, minimize environmental impact, and protect high-pressure drilling equipment from abrasive solids.

The GN C Series represents a flagship solution for medium to large-scale drilling operations. Unlike basic economy models, the C Series integrates mud recycling, storage, and mixing functions into a single, self-contained package, eliminating the need for separate storage tanks and mixing equipment. Available models include:

GNMS-200C: 200 GPM (50 m³/h)
GNMS-400C: 400 GPM (100 m³/h)
GNMS-600C: 600 GPM (150 m³/h)
GNMS-1000C: 1000 GPM (200 m³/h)

For slurry shield tunneling and pipe jacking projects, GN manufactures complete TBM slurry separation plants designed to handle the large volumes of slurry mixed with sand and stones generated during excavation. These plants are engineered to deliver high-performance solid-liquid separation, maintaining tunnel face stability, reducing cutter wear, and ensuring smooth TBM operation.

GN TBM slurry separation plants are available in multiple configurations to suit different tunnel diameters and project scales:
GNTBM-260B: 260 m³/h processing capacity
GNTBM-360B: 360 m³/h processing capacity
GNTBM-500B: 500 m³/h processing capacity

GNTBM-500 Underground Engineering Slurry Separation Plant for Asia

GNTBM-500 TBM slurry separation plant is a high performance mud treatment system for Construction Engineering.


Modern construction and civil engineering projects—such as bored piling, diaphragm walling, and tunnel boring—generate large volumes of engineering mud. Efficiently treating the slurry is critical for both project economics and environmental compliance. The GNTBM-500 is designed to meet this challenge head-on.
Features of GNTBM-500 slurry separation unit including:
1. GNTBM-500 can efficiently treat construction engineering mud with a processing capacity of up to 500 cubic meters per hour.


2. Three stage separation for Cleaner, Faster and Smarter.
The first stage separation is coarse solids separation shale shaker, which is the lower deck of the double deck shale shaker, the second stage separation is desander cone, the third stage separation is desilter cone, the top layer shaker screen is as the mud cleaner shaker screen to dry the discharged solids.
3. Integrated tanks and VFD control — stable and energy-efficient.
The GNTBM-500 comes with integrated mud tanks and Variable Frequency Drive (VFD) control. The built-in tanks simplify site layout and reduce external piping, while VFD technology allows precise adjustment of pump and centrifuge speeds. This combination delivers stable mud circulation under varying load conditions and significantly cuts power consumption—lowering your operating costs and carbon footprint.


4. Compact & Modular : Ready for rapid deployment
Space and time are often limited on construction sites. The GNTBM-500 features a compact, modular design that can be easily transported in standard containers or flat-rack units. On arrival, it requires minimal assembly and can be operational within hours. For contractors working on urban projects or remote sites with tight schedules, this rapid deployment capability is a game-changer.
Except for 500m3/h TBM slurry separation plant, GN also produce different treating capacity TBM slurry separation plant, like GNTBM-260B, GNTBM-360B, etc, pls contact GN solids fo
