GN GNTBM-500B Slurry Separation System Delivered for Middle East TBM Project

GN Solids has successfully completed the manufacturing and inspection of a GNTBM-500B Slurry Separation System, which will be deployed for an underground tunnel construction project in the Middle East. This advanced slurry treatment solution is designed to support Tunnel Boring Machine (TBM) operations by efficiently separating excavated solids from slurry and recycling valuable drilling fluid.

With a processing capacity of up to 500 m³/h, the GNTBM-500B is engineered for medium and large-scale underground construction projects, including TBM tunneling, slurry shield projects, pipe jacking, and other trenchless engineering applications. The system helps contractors maintain stable slurry performance, reduce waste transportation costs, and improve overall construction efficiency.

The GN GNTBM-500B integrates multiple separation stages into a compact modular structure. The incoming excavation slurry first passes through a high-performance vibrating screen to remove large particles such as stones, gravel, and coarse sand. The treated slurry then enters hydrocyclone separation units, where finer solids are removed to achieve effective slurry purification. The cleaned slurry can be returned to the TBM circulation system for reuse, supporting environmentally responsible construction practices.

Designed with a space-saving layout, the GNTBM-500B features integrated tanks, pumps, and separation equipment mounted on a robust steel structure. This modular design allows easier transportation, installation, and commissioning, which is especially important for urban and underground projects where working space is limited.

Hebei GN Solids Control is a professional manufacturer specializing in solids control equipment and solid-liquid separation systems. With extensive experience in TBM slurry treatment, GN provides customized solutions including vibrating screens, desanders, desilters, slurry pumps, and decanter centrifuge systems for global infrastructure projects.
