GN Solids Control's upgraded slurry separation plant series, including GNTBM-240, GNTBM-360, GNTBM-500, GNTBM-800, GNTBM-1000, GNTBM-1500 and systems scalable up to 3,000 m³/h, supports high-capacity slurry treatment for TBM and underground construction projects.
HOUSTON, May 4, 2026 /PRNewswire-PRWeb/ -- GN Solids Control, a global manufacturer of solid-liquid separation and slurry treatment equipment, this year launched its New Generation Slurry Separation Plant for Tunnel Boring Machine (TBM) slurry balance tunneling, pipe jacking, diaphragm wall construction, and large-scale underground infrastructure projects.
The upgraded system is designed to meet the increasing demand for efficient, reliable, and environmentally responsible slurry treatment in subway tunnels, railway and highway tunnels, utility tunnels, cross-river and cross-sea tunnels, and other underground projects.
GN's new generation plant integrates multi-stage separation, intelligent VFD control, modular structure, and low-energy operation to improve slurry recycling, reduce waste mud discharge, protect downstream equipment, and lower total project cost.
Core Technical Advantages
1.High-Capacity Processing Range
GN's TBM slurry separation plant is available in standard models including GNTBM-240, GNTBM-360, GNTBM-500, GNTBM-800, GNTBM-1000, GNTBM-1500 with system capacity scalable up to 3,000 m³/h through modular combination. The system can be configured according to tunnel diameter, slurry flow rate, ground condition, solids content, and jobsite layout.
2.Multi-Stage High-Efficiency Separation
The plant adopts a multi-stage separation process to remove solids from coarse particles to fine solids:
- Scalping vibrating screen removes coarse gravel, stones, and large debris.
- Desander cyclone unit separates medium sand particles and reduces abrasive solids.
- Desilter cyclone unit captures fine solids down to approximately 20 microns.
- Optional decanter centrifuge further purifies slurry for ultra-clean recycling or stricter discharge requirements.
The complete system can also include bottom drying shakers, centrifugal pumps, mud tanks, agitators, pipelines, walkways, electrical control panels, and other auxiliary equipment.
3.Modular and Containerized Design
With a compact, pre-assembled, skid-mounted, and containerized design, GN's slurry separation plant enables fast transportation, quick installation, easy disassembly, and repeated relocation between jobsites. This is especially suitable for urban tunneling projects where space is limited and project schedules are tight.
4.Intelligent Control and Stable Operation
The system can be equipped with full-process VFD control, real-time monitoring, automatic adjustment, and fault self-diagnosis. This helps operators optimize flow rate, reduce manual intervention, and maintain stable 24/7 operation under changing slurry conditions.
5.Eco-Friendly and Cost-Effective Performance
Efficient slurry separation helps maximize slurry recycling, reduce fresh water consumption, minimize waste mud volume, and lower wear on pumps, pipelines, cyclones, and TBM slurry circulation components. By maintaining stable slurry properties, the system supports higher tunneling efficiency and reduced downtime.
Market and Application Value
Slurry separation is critical for TBM tunneling because clean and stable slurry helps maintain excavation face pressure, improve tunneling speed, protect equipment, and reduce environmental impact.
GN's new generation slurry separation plant is suitable for:
- Subway and metro tunnels
- Highway and railway tunnels
- Urban utility tunnels
- Cross-river and cross-sea tunnels
- Water transmission tunnels
- Pipe jacking projects
- Diaphragm wall construction
- Deep foundation engineering
