From gravel from the rock face through railway ballast and on to building rubble: there’s no question that when such a wide variety or materials are loaded on the machines, multi-talents are in demand. A perfect environment for the new Kleemann screen for coarse elements MOBISCREEN MSS 802i EVO. In Germany, the first machine of the new design started work in Neumünster. We took a look at how the new plant performed in concrete practice.
Ernst Krebs GmbH & Co. KG in the far north between Hamburg, Germany, and Kiel, Germany, is very diversified. Owner Caren Krebs and her son André operate several gravel quarries. The company portfolio includes demolition and recycling work, earthwork, road construction and also a transport and logistics section.
The company’s machinery was to be extended in 2021 by a new screening plant. The requirements: The plant had to be flexible, above all, and perform in the gravel quarry just as well as on the recycling site – which is not an easy task.
After all, whereas sand and fine-grained material are processed in the gravel quarry, in the recycling of rubble and railway ballast Krebs processes almost everything. Also including, for example, topsoil which is often particularly cohesive. The screening plant therefore has to deal with stone material ranging from very fine to very coarse as well as with all degrees of contamination.
André Krebs took his request to his contact partner at Wirtgen Germany, Henning Lüdtke, with whom he has been working together from many years. After hearing the task description, it was clear to Henning Lüdtke: This is the ideal application area for the new Kleemann screen for coarse elements MOBISCREEN MSS 802i EVO. After all, the real strength of the Kleemann new development is its high flexibility and productivity.
