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.

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 Hydraulic Drive Mini Centrifuge Unit for Diamond Core Drilling

3 package of hydraulic drive mini centrifuge unit are shipping to diamond core drilling.
The key features of GN hydraulic drive mini centrifuge unit including:
1. Drive system: Hydraulic motor powered by a diesel engine, compared with electrical motor drived centrifuge, the hydraulic drive centrifuge system can be applied in remote area where electricity power is limited, and the hydraulic drive system can provide high torque and variable speed control to handle fluctuating loads.


2. Design and portability: GN hydraulic mini centrifuge system adopts a modular design and lightweight to meet the requirements for helicopter hoisting. The skid modular design is for easy installation and disassembly, easy to relocate and set up on confined drill pads.
3. Separation performance: The system is a complete mechanical separation without adding chemicals to reduce the chemical cost, it can improve the performance of drilling fluids and enhancing drilling efficiency. The high G force decanter centrifuge can generates 2492G to remove ultra-fine solids down to 2-5 microns; maintains stable mud properties, reduces bit wear, and improves core sample quality.
4. System components: The hydraulic drive centrifuge system including mini hydraulic centrifuge, hydraulic drive system, diesel engine, mud tank, feeding pump, mixing pump, mixing hopper, it forms a complete, closed-loop mud recycling system; allows for immediate reuse of treated water
Why should we use the hydraulic drive centrifuge system?


(1) Operational Independence: It completely removes the dependency on unreliable or non-existent local power grids, ensuring operations can continue uninterrupted in the world’s most remote locations .
(2)Environmental Compliance: By recycling water and drastically reducing the volume of drilling waste, it helps drilling companies meet stringent modern environmental standards and reduce their overall ecological footprint .
(3) Cost Efficiency: Lower water consumption, reduced chemical usage, less waste transportation, and decreased wear on drill bits and pumps all contribute to significant project savings .
(4)Enhanced Drilling Performance: Maintaining consistently clean mud improves the rate of penetration, extends the life of downhole tools, and most importantly, enhances the quality of the core sample retrieved
