GN Solids, showcased its cutting-edge equipment at the International Trenchless Technology Conference (ITTC) 2025. With a focus on innovation and efficiency, the company highlighted two flagship products designed to address the challenges of modern tunneling and drilling projects: the TBM Slurry Separation Plant and the GNLW632B Dewatering Decanter Centrifuge.
1. TBM Slurry Separation Plant
GN Solids’ TBM Slurry Separation Plant are engineered to deliver high-performance solid-liquid separation for slurry shield tunneling and pipe jacking projects. These systems are particularly suited for urban construction sites where space constraints and high processing efficiency are critical.
Key Features:
Compact Vertical Design: The system maximizes space utilization by arranging equipment vertically, reducing the overall footprint while maintaining robust processing capabilities.
Modular Configuration: The modular design allows flexible combinations to meet diverse project demands. Systems can be assembled into large-capacity setups or split into smaller units for localized operations. This adaptability also supports rapid disassembly and relocation, ideal for mobile construction needs.
High Processing Capacity:
GNTBM-260B: 260 m³/h
GNTBM-360B: 360 m³/h (equipped with GNZS1536-2A high-efficiency double-layer vibrating screen, vibrating amplitude 4-8 mm)
GNTBM-500B: 500 m³/h
Customizable Solutions:
GNTBM-800B (800 m³/h): Combines GNTBM-360B + GNTBM-500B
GNTBM-1000B (1000 m³/h): Dual GNTBM-500B units
GNTBM-1500B (1500 m³/h): Three GNTBM-500B units
Full System Components:
The complete TBM Slurry Separation Plant includes vibrating screens, desanders, desilters, bottom drying screens, slurry feed pumps, and slurry circulation tanks. These components work synergistically to ensure efficient slurry recycling, reduced waste, and enhanced operational continuity for medium to large tunneling projects.
2. Dewatering Decanter Centrifuge: GNLW632B
The GNLW632B Decanter Centrifuge is a game-changer for non-excavation projects requiring fine particle separation. It excels in processing slurry from clay, fine sand, and mudstone formations, offering sustainable and cost-effective solutions.
Key Advantages:
Chemical-Free Operation: Effectively reduces slurry specific gravity and restores slurry properties without chemical additives, minimizing environmental impact.
Compact and Automated: Designed for small footprints, the centrifuge operates continuously with minimal human intervention, ensuring reliability in demanding environments.
Waste Reduction: By optimizing slurry reuse and lowering disposal volumes, the GNLW632B significantly cuts down on waste generation and associated costs.
