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:

4 Sets GN Mud Cleaning System for Europe HDD company

Recently 4 sets of GN mud cleaning system are ready for delivery to Europe HDD company, including 3 sets of GNMS-200C HDD mud recycling system with treating capacity 200gpm, 1 set of GNMS-1500 HDD mud recycling system with treating capacity 1500gpm.


GNMS-200C HDD mud recycling system is a 200gpm self contained mud recycling system, the cut point is 25 microns, the total volume is 5m3. It is a 2 phase cleaning mud system, the first phase cleaning is double deck shale shaker bottom screen for coarse solids separation, the second phase cleaning is 4pcs of 4 inch desilter cone with mud cleaner. 2 units of centrifugal pumps in same model as desilter feeding pump and a mud mixing pump.


GNMS-1500C HDD mud recycling system is a customized 1500gpm mud recycling system, the cut point is 25 microns. Except for high configuration mud recycling system, GN solids control also produce compact design mud cleaning unit for trenchless HDD project, Bored pile project and micro TBM project, diamond core drilling, water well drilling project. GNMS-200K mud cleaning unit with 200gpm capacity, GNMS-500K with 500gpm capacity, GNMS-1000K with 1000gpm capacity.


Compared with the compact design mud recycling system and the self contained mud recycling system, the table below breaks down the key differences between the two types of systems:

Feature Compact design mud cleaning unit Self contained mud recycling system
Primary function Focus on cleaning Performs mud cleaning, mixing and storage
System complexity Simpler, often a two stage separation process More complex, typically a 4 stage separation process for finer solids separation
Footprint Smaller, skid mounted design for easy transportation Larger, skid mounted or trailer mounted with bigger tanks for greater fluids volume
Application For smaller jobs, supporting smaller drill rig Suited for middle sized to large projects requiring high volume, fine cleaned mud.

3 Package HDD Mud Reycling Unit for Europe Client

Recently three packages of HDD mud recycling unit are ready for delivery to Europe client, including 2 sets of GNMS-400C HDD mud recycling system and 1 set of GNMS-200C HDD mud recycling unit.


There are 2 types mud recycling unit produced by GN, the economic HDD mud recycling system are largely used in HDD mud cleaning and recycling without mud storage and mixing function, an extra storage tank and a mixing unit are needed. The self contained mud recycling system integrated with the function of mud recycling, mud storage and mud mixing, it can meet the large drilling rigs mud recycling requirement. We can produce different treating capacity mud recycling system, such as 200gpm, 400gpm, 600gpm, 1000 gpm and customized treating capacity mud system. They can be used for trenchless HDD project, CBM drilling, geothermal drilling, tunnel boring machine or bored pile project, water well drilling and diamond core drilling.


GNMS-200C HDD mud recycling unit is a 200gpm treating capacity mud recycling system, including double deck mud cleaner with hydrocyclones, feeding pump, mixing pump, mixing hopper, mud agitator and mud gun, the mud tank can be shipped by standard contaianer,
GNMS-400C HDD mud recycling system is a 400gpm capacity mud system, the total storage capacity is 8.5m3, the container shipping dimension is 6000mm x 2220mm x 2158mm. The mud cleaner is a double deck bottom shaker with 8ea of 4 inch desilter cone, with feeding pump and mixing pump.
Except for HDD mud recycling unit, we also produce TBM slurry separation plant, the features of TBM slurry separation plant including:
1. Complete package for Turnkey solution

The walkway and guardrail around the mud tank for convenient operation, the control panel is installed for easy operation for people stand on the ground.


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.
