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
