System Overview
The KOSUN  KD-500 slurry separation system adopts a modular structural design and is specifically developed for slurry purification requirements in medium- and large-scale slurry balance shield tunneling projects. It offers strong adaptability and stable operation.
The core of the slurry separation system consists of three main modules: a coarse screening module, a desanding module, and a desliming module, which work together to achieve step-by-step slurry purification.
The coarse screening module serves as a pre-screening unit, quickly removing large solid debris from the slurry and laying the foundation for subsequent fine treatment.
The desanding module is equipped with a primary desanding hydrocyclone and a fine-mesh vibrating screen, focusing on removing smaller sand particles from the slurry to achieve higher purification accuracy.
The desliming module is fitted with a secondary desliming hydrocyclone, enabling flexible and selective fine separation according to on-site construction requirements, thereby meeting different purification standards.
The system adopts a closed-loop slurry circulation purification mode, and the treated waste residue has low moisture content, effectively reducing environmental pollution at the source. In addition, all internal components are made of anti-corrosion and wear-resistant materials, ensuring long service life and low failure rates. This allows the system to reliably handle various harsh construction conditions and ensure continuous operation.
 
Process Flow
The drilling slurry first enters the coarse screening module, where large solid particles are removed. It then flows into the desanding module, where a primary hydrocyclone separation system and a fine-mesh vibrating screen further remove sand particles.
Finally, the slurry enters the desliming module, where a secondary hydrocyclone is used to achieve fine particle separation and purification.
The treated slurry is then returned to the circulation system, enabling a closed-loop slurry recycling process.
