Economic further utilization
Recycling of the excavated tunnel material helped achieve two central objectives: conservation of resources combined with savings on costs. Recycling plays an important role for CRCC – in this area, the technologies from KLEEMANN provided valuable support.
The bulk of the material, 300,000 m³ of limestone, was processed near to the tunnel construction site. This is also made a big contribution to efficiency and thus cost-effectiveness. After all, short routes mean: fewer trucks, less fuel, lower emissions. When they arrived at the work site, the construction vehicles unloaded the stones, where bucket excavators then loaded them into the MOBIREX. Following the crushing process, the MR 130 Z EVO2 transferred the material to a MOBISCREEN triple-deck screening plant MS 19 D. Overall, four classified final products were thus created with an output of 230 t/h. The plant team even had large capacity reserves as the maximum output is twice as high.
