en.Wedoany.com Reported - Germany's Kleemann company recently presented a crushing and screening equipment line for asphalt processing. The screening line consists of the MOBISCREEN MSS 502 EVO screening machine, the MOBIREX MR 100 NEO impact crusher, and the MBT 20 stacking conveyor, demonstrating the seamless collaboration of the equipment, with a focus on processing uniform gradations and producing high-quality aggregates.

The more asphalt and aggregates recovered from Reclaimed Asphalt Pavement (RAP), the more significant the benefits. A rough guide shows that increasing the RAP addition rate from 20% to 60% can save approximately 40% in costs and reduce emissions by about 20%.

Proper pre-screening reduces the amount of material to be crushed, lowering crusher wear and energy consumption while keeping the fines content low, which is the foundation for achieving higher RAP addition rates and stable mix designs. The equipment line demonstrates a continuous recycling cycle: starting with Kleemann's parent company Wirtgen's milling machines performing selective milling of the surface, binder, and base courses, over 60% of the milled material can be directly reused. After the asphalt layers are extracted separately, the quality of the recycled material is significantly improved. Following screening and crushing by Kleemann equipment, the processed material is reused in the asphalt mixing plant. Equipment from Vögele and Hamm completes the cycle through paving and compaction, forming a complete process from demolition and processing to reuse.
