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 working process is as below:
The transfer pump feed the slurry to the double deck shale shaker lower deck through the coarse screening inlet pipe, to remove the coarse solids from the slurry. The built in #1 slurry pump transfer the slurry separated by coarse screening to desander cone, the clean mud flow out from the overflow port, the cuttings is discharged from the desander drop in apex, and fall on the upper deck of the double deck shale shaker to recover more useful fluids. The built in #2 slurry pump feed the clean mud to desilter cone, the clean fluids flows out from the desilter upper part, and overflows to the storage tank outside the system, which can be reused for the TBM machine. The solids particles will be dried and collected for disposal.
