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

1. HDD mud recycling system: GN HDD Mud Recycling System (Horizontal Directional Drilling Mud Recycling System) is a modular solids control solution designed to recover and reuse drilling fluids (bentonite mud) in trenchless industry. It reduces waste disposal costs, minimizes environmental impact, and protects high-pressure pumps by removing excavated solids .The system typically integrates multi-stage separation and auxiliary components on a single skid mounted mud tank or trailer mounted mud tank. Here is the standard configuration breakdown: the 1st stage: shale shaker to separate coarse solids; the 2nd stage: desander cone to separate the cut point 45~75 microns; 3rd stage: desilter cone to separate cut point 25~45 microns; the 4th stage: decanter centrifuge to remove ultra fine solids; The other equipments including customized design mud tank, mixing hopper, mixing pump, electrical control system, lightings, mud agitators, etc.


2. TBM slurry separation system: GN TBM (Tunnel Boring Machine) Slurry Separation System is a high-capacity solids control solution engineered specifically for Slurry Shield TBM and Microtunneling projects. It is designed to separate excavated soil and sand from bentonite slurry, allowing for continuous recycling of the drilling fluid and efficient management of muck disposal. GN offers standardized skid-mounted or containerized plants based on TBM diameter and excavation rate: GNTBM-260 (260m3/h), GNTBM-360 (360m3/h), GNTBM-500 (500m3/h), GNTBM-800B (800m3/h), GNTBM-1000B (1000m3/h), GNTBM-1500B (1500m3/h) and higher treating capacity TBM slurry separation plant up to 3000m3/h for Large Diameter Road/Rail Tunnels.

6 Package of TBM Slurry Separation Plant for South Korea

GN Solids control delivered 6 packages of TBM Slurry Separation Plants to a major infrastructure project in South Korea. Specifically engineered for slurry balance TBM applications, these systems offer high-efficiency processing capacities of 500 m³/h and 750 m³/h.


To meet the rigorous demands of Korean shield tunneling projects, each plant integrates a three-stage core treatment process: a scalping shaker for coarse solids separation, followed by desander and desilter modules for fine particle control. The entire system utilizes a modular design, which ensures a compact footprint, facilitates easy assembly and disassembly on-site, and significantly reduces logistics costs. Our professional separation technology guarantees stable performance and high-quality slurry recovery, ensuring the smooth progress of tunneling operations.


The 6 units of TBM slurry separation plant including 4 sets of GNTBM-500B TBM slurry separation plant and 2 sets of GNTBM-360B TBM slurry separation plant and 6 sets of extra mud tanks, the technical configuration is as below:
GNTBM-360B TBM slurry separation plant, treating capacity 360m3/h, cut point 25~50 microns, one unit of coarse shaker installed slopped opening polyurethane screens, to remove large cuttings and gravel to protect downstream pumps and equipment. installed 2ea of 16 inch desander cone and 10ea of 6 inch desilter cone, 2ea of 75KW centrifugal pump as feeding pump of the desander cone and desilter cone.


GNTBM-500B TBM slurry separation plant, treating capacity 500m3/h, cut point 15~30 microns, one unit of coarse shaker installed slopped opening polyurethane screens, installed 2ea of 20 inch desander cone and 14ea of 6 inch desilter cone, 2ea of 90KW centrifugal pump as feeding pump of the desander cone and desilter cone.
