KOSUN KD Series Slurry Separation Solutions for TBM & Piling Construction

Dec 23, 2025

In modern infrastructure construction, slurry treatment efficiency and environmental compliance are critical elements of project management. The KD Series Slurry Separation Plant, developed by KOSUN, is specifically designed for circulation drilling processes and shield tunneling, providing technical support for slurry purification, recycling, and waste minimization.

 
KD Series: Slurry Treatment Equipment for Diverse Working Conditions
 
The KOSUN KD Series Slurry Separation Plant is dedicated to slurry purification for Slurry Shield TBM, diaphragm walls, and piling foundations. Utilizing this system optimizes slurry properties, improves hole-making quality and operational efficiency, ensures the safe operation of excavation equipment, and significantly increases the slurry recycling rate. This contributes to reducing construction costs and slurry discharge, meeting the requirements of green construction.
The internal components and wear parts are manufactured from anti-corrosive and abrasion-resistant materials, featuring a long service life and low failure rates, making the system adaptable to various complex working conditions.
 
Modular Design & High-Precision Slurry Separation Technology
 
The KD Series Slurry Plant primarily consists of three core modules: the Scalping Module, the Desanding Module, and the Desilting Module.
 
Scalping Module: Acts as a pre-screener to remove oversized rocks and coarse debris from the slurry.
Desanding Module: Equipped with Desander Hydrocyclones (primary cyclones) and a fine-mesh shale shaker, primarily for removing sand-sized particles.
Desilting Module: Equipped with Desilter Hydrocyclones (secondary cyclones), providing optional precision separation based on specific project requirements.
 
The system adopts a closed-loop circulation purification method. The discharged filter cake has a low moisture content, significantly reducing environmental impact.
 
High Integration & Versatility Drilling Mud Cleaning System
 
KOSUN KD Series Solids control slurry separation plant offer the following design features and advantages:
 
Modular & Compact Design: The slurry plant features a modular integrated design based on ISO container dimensions, facilitating easy logistics and rapid commissioning. The compact structure, paired with foldable walkways and platforms, minimizes the onsite footprint.
Ease of Operation & Maintenance: The streamlined and practical process flow reduces the complexity of installation, operation, and daily maintenance for onsite personnel.
 
KD Series: Highly Customization Solutions
 
Adjustable Performance Parameters: The G-force, deck angle, and screen mesh size (API size) of the shale shakers are all adjustable, allowing the system to handle materials from diverse and complex geological strata flexibly.
Capacity Configuration: Based on geological conditions and material characteristics, the system can achieve customized D50 cut-point control to meet specific separation requirements. Various throughput capacity options are available.
Flexible Power Solutions: The system can be configured to meet different global electrical standards or equipped with an onboard diesel generator set for independent operation.
Mobile Deployment: Supports skid-mounted integration or can be configured as a fully trailer-mounted mobile unit, enhancing mobility between different work sites.
 
Application Fields of KD Slurry Separation Plant
 
The KOSUN KD Series Slurry Separation System is widely applied in the following sectors:
 
Slurry Balance Shield (TBM) slurry treatment.
Bored Piling Construction (suitable for Rotary Drilling Rigs, Forward/Reverse Circulation Rigs, and Impact Drills).
Diaphragm Wall Construction (suitable for Hydraulic Grabs and Trench Cutters/Hydrofrezes).
Trenchless Technology (suitable for Horizontal Directional Drilling (HDD) and Slurry Pipe Jacking).
