Kleemann exhibited its practical solutions for asphalt processing at the IFAT environmental technology show.
Forward-looking solutions for water, recycling, and circularity were the focal points at the trade fair in Munich, Germany (May 4-7).
The Kleemann scalping screen MOBISCREEN MSS 502 EVO, impact crusher MOBIREX MR 100 NEO and stockpile conveyor MBT 20 demonstrated the seamless interaction of the Kleemann plants on site in the Crushing Zone. The focus here was on the processing of homogeneous fractions and the production of high-quality aggregates.
Visitors were able to experience this first-hand and vividly in the immediate vicinity of the plant train. It became clear that the more bitumen and aggregate from reclaimed asphalt pavement (RAP) is reused, the better. As a rough guide: Increasing the RAP addition rate from 20% to 60% can lead to cost savings of around 40% and an emission reduction of approximately 20%.
Suitable prescreening reduces the mass to be crushed, lowers wear and energy consumption in the crusher, and simultaneously keeps the content of fines lower. This is the basis for higher RAP addition rates and constant recipes.
The plant train on display demonstrated these advantages and is part of a continuous recycling loop: This begins with the selective milling of the surface course, binder course and base layer using milling machines from Kleemann owner Wirtgen. In many cases, more than 60% of the milled material can be reused directly.
Separate extraction of the asphalt layers significantly improves the quality of the recycled material. After screening and crushing with the Kleemann plants, the processed material is reused in asphalt mixing plants. Machines from Vögele and Hamm close the circle with installation and compaction. This results in an efficient, sustainable process – from removal and processing to reuse.
As a co-exhibitor of VDMA Services GmbH, Kleemann exhibited as part of the Crushing Zone (VDMA) – a manufacturer-independent demonstration area that brings innovative processing and recycling technology to life in a technology-neutral, practical, and future-oriented manner.
