Recently, HL Solids Control successfully delivered five sets of Schlamm-Trennsysteme for Tunnel Boring Machines (TBM) to Indonesia. These systems will be widely used in slurry shield tunneling projects, providing efficient slurry treatment solutions and supporting the rapid development of underground infrastructure in Indonesia.
With high separation efficiency, compact design, and easy deployment, HL’s slurry separation systems once again demonstrate the global competitiveness of Chinese solids control equipment in international markets.
Growing Demand for Slurry Separation Systems in Indonesia
In recent years, Indonesia has experienced rapid growth in underground infrastructure construction, including:
- Power cable tunnels
- Municipal underground pipeline networks
- Urban transit systems
The slurry shield TBM method has become increasingly popular due to its:
- High construction efficiency
- Minimal environmental impact
- Strong adaptability to complex geological conditions
However, slurry separation is a critical part of TBM operations. It directly affects:
- Tunneling efficiency
- Face stability
- Environmental compliance
This creates a strong demand for high-capacity, high-precision, and reliable slurry separation equipment.
Customized Slurry Separation Solutions for Indonesia Projects
HL Solids Control has developed tailored solutions to meet the specific needs of the Indonesian market. The exported systems are designed with:
- Processing capacities of 500 m³/h and 750 m³/h
- Flexible configuration for different TBM project scales
- Adaptability to various geological conditions, including:
- Hard rock
- Weathered rock
- Mixed formations
These systems are suitable for both:
- Medium and small-scale tunneling projects
- Large, long-distance TBM operations
Advanced Multi-Stage Separation Technology
Each slurry separation system is equipped with three core modules:
1. Coarse Screening Unit
- Removes particles ≥300 microns
- Acts as the first-stage pre-treatment
- Protects downstream equipment and improves efficiency
2. Desander Unit
- Removes particles between 74–300 microns
- Reduces sand content to below 3%
- Ensures stable slurry performance
3. Entsilter Unit
- Separates fine particles (20–74 microns)
- Maintains slurry density and viscosity
- Enables reuse of drilling slurry
This multi-stage separation process follows the principle of:
👉 “Gradual purification and recycling utilization”
It significantly improves resource efficiency while reducing environmental impact.
Supporting Sustainable and Efficient Tunneling
By reusing treated slurry, these systems help:
- Senkung der Betriebskosten
- Minimize waste discharge
- Meet strict environmental regulations in Indonesia
This makes HL’s slurry separation systems an ideal solution for eco-friendly tunneling operations.
Strengthening Global Presence of Chinese Solids Control Equipment
The successful delivery of these five systems highlights HL’s strong capabilities in:
- Engineering design
- Manufacturing quality
- International project execution
It also marks another milestone in expanding into Southeast Asian markets, especially Indonesia, where demand for TBM slurry treatment systems continues to grow.
