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.
The modular TBM slurry separation plant is installed on top of the extra customized size mud tanks. If you need a customized design TBM slurry separation plant, pls contact with GN solids engineer.

 

GNTBM-320 TBM Slurry Separation Plant for China Client

Recently one set of GNTBM-320 TBM Slurry Separation Plant are ready for delivery to China client. The technical parameter is as below:
1. Total power :67KW
2. General treating capacity; 320m3/h (excluding clay layer usage conditions)


3. Basic structure, consists of double deck linear motion shale shaker, hydrocyclones, 55KW slurry pump, 24m3 treatment tank, electric control system, guardrails, pipelines, etc.
The double deck shale shaker with screening area total 8.64m2, the top layer screen opening is 0.5mm, the bottom layer screen opening is 3mm. The vibration motor drived the shale shaker is 2ea of 6KW, with frequency 16HZ. The hydrocyclone installed on top of the double deck shale shaker material is polyurethane inside, outside covered with casting steel, the single cone capacity is 80~180m3/h, the pressure required is 0.06 ~0.2Mpa.
4. Applicable environmental conditions :
Ambient temperature: -18 ¬°C ~+40°C
Altitude height: ≤1000m
Ambient humidity:≤90% (+20°C)
Non explosion proof


5. The equipment can adapt to weather conditions containing 5% sand and dust, as well as rain, snow, fog, etc.Suitable for long distance transportation such as highway, railway, and sea freight, meeting the requirements of crane loading and unloading, and suitable for frequently movement and installation, and it is corrosion and leakage prevention.
6. The TBM slurry separation plant can meet the requirement of pipe jacking construction process.
7. The system design separation cut point is 30 microns, the solids over 30μm can be separated out by the hydrocyclone separation.
The function of the TBM slurry separation system is to pump the drilling mud to the buffer tank of the shale shaker, after separation, the coarse solids are separated out from the shale shaker, the fine solids dropped into the mud tank with the liquids.
