MOBICONE MCO 90i EVO2 in its first practical application
New cone crusher produces first-class railway ballast and high-grade flint
For cost-effective recycling and the production of high-quality ballast chips and high-grade flint, the Erdtrans company group invested in a mobile cone crusher MOBICONE MCO 90i EVO2 from Kleemann. Since summer 2021, the first plant of this type worldwide has been recycling mainly railway ballast. Downstream of the cone crusher is a screening plant MOBISCREEN MS 953 EVO. Both machines impress with regard to quality and output – as stand-alone machines and as a team.
To guarantee fast and safe train travel, the ballast bed under railway tracks has to be regularly repaired. High demands are placed on the material because, in a high-quality ballast bed, the stones dig into one another with their sharp edges to form a stable base. Furthermore, only suitable material gives the track system the required elasticity and ensures the unrestricted downward flow of rainwater. German Railways (DB) uses licences for the railway ballast suppliers to ensure that the material used meets the requirements. The Erdtrans company group with offices in Zossen and Trebbin near Berlin has had corresponding DB product qualification for years because "we recycle or process everything that's under the rails", explains Michael Schwarzer, Erdtrans Managing Director in the second generation.
