The mobile STE 100.65 TV PB jaw crusher from SBM is designed for high-performance, high-performance applications and has a compact dimension of 19 m in length, 2.65 m in width, 4.2 m in height and a weight of 57.5 tons. The height of the feed hopper is 2 m, which allows a supply by wheel loaders directly in the tunnel. Those are very useful features for the 5,860 m long Albula tunnel site in Switzerland, which is drilled and blasted. To allow the excavated material to be removed by conveyor belts up to 3 km long (and equipped with a powerful magnetic separator to avoid damage), the granite / dolomite pieces must be pre-grounded at 0-150 Mm. A stage realized directly in the tunnel by two crushers SBM. The power supply is provided by a three-phase motor developing 132 kW for a capacity of 250 t / h for each of the machines. The STE 100.65 TV PB can accept materials up to 700 mm with an opening of 1000 x 650 mm. But to ensure the proper functioning of the machine, the teams on site also provided the mill with a pre-screening machine with dimensions of 1,500 x 1,000 mm. This configuration would increase hardware performance by 30% and ensure constant transport of the finished material.
