The Black Rhino KD series mud-water separation system is a closed-circuit mud circulation purification system designed specifically for treating construction mud in infrastructure projects. With superior and reliable performance, low slag moisture content, and high durability, this mud-water separation system has earned praise from industry customers worldwide. Whether you are working on tunnels, foundations, or pipelines, the KD series delivers consistent results.

Wide Applications Across Infrastructure Construction
The KD series is highly versatile, serving numerous applications including mud and water balance shield construction, horizontal directional drilling (HDD) , underground diaphragm walls, bored pile foundations, pipe jacking, and tail slurry treatment. No matter the project, the KD series adapts to the job.
System Composition and Working Principle
The KD series consists of four core components: a shaker screen, sand cyclone, sand gravel pump, and conical tank. The shaker screen uses both coarse and fine screens. The coarse screen removes larger particles, while the sand cyclone and fine mesh screen remove smaller sand particles. This closed-circuit purification ensures low water content in the slag, reducing environmental pollution and disposal costs.
Durability and Reliability for Harsh Conditions
One of the key strengths of the Black Rhino KD series is its robust construction. The equipment accessories have a long service life and a low failure rate, making the system suitable for various bad working conditions — from extreme temperatures to abrasive formations. When you are working in tough environments, a mud-water separation system that stays online and performs reliably is not a luxury; it is a necessity.
KD-500 Model: High Performance for Double-Wheel Milling
The KD-500 is designed for double-wheel milling underground continuous wall construction. It achieves 500 cubic meters per hour processing capacity with separation down to 30–40μm. Its unique second and third-stage separation switching technology allows operators to handle different formation requirements without changing equipment.

The Black Rhino KD series efficiently separates mud and water for infrastructure projects like tunneling, HDD, diaphragm walls, bored piles, and pipe jacking. The KD-500 model handles 500 m³/h with 30–40μm separation. Durable, low-maintenance, and trusted by professionals.
