| Customer | GIE GMM 73 |
| Industry | Aufbereitungstechnik |
| Location | Saint-Julien-Montdenis ¦ France |
| Realisation | 2024 – 2026 |
Special Features / Highlights
- Two identical, fully integrated processing plants operating in parallel, each with a feed capacity of 250 t/h, supplying the tunnel construction sites
- Comprehensive water treatment system with two chamber filter presses for efficient sludge dewatering
- Large-capacity silo system for intermediate storage of aggregates for concrete production
Project Description
As part of the international Tunnel Euralpin Lyon Turin project, two comprehensive material management and processing plants operating in parallel were implemented for the treatment and reuse of tunnel excavation material.
The two processing lines combine mechanical rock processing with multi-stage screening and classification processes as well as high-capacity sand and aggregate production. Extensive conveying, distribution, storage and silo systems ensure efficient material flow. The overall system is complemented by a closed-loop water and sludge treatment system comprising high-rate clarifiers, process water circuits and chamber filter presses.
The scope of supply included the planning, delivery and commissioning of the plants, as well as the complete electrical, control and automation systems, including visualization and process monitoring.
Despite the highly variable properties of the excavation material, the coordinated processes ensure reliable and cost-effective treatment. This enables the production of high-quality sand and aggregates for further use.
