C&D Waste Processing — Impaktor 250 EVO II
// INDUSTRIAL FRICTION
Construction and demolition waste streams present a composite processing challenge: reinforced concrete crushing efficiency depends on the ability to handle rebar-contaminated feedstock without secondary liberation stages. Traditional jaw crushers and impact breakers generate uneven particle-size distributions that fail to meet aggregate-recycling specifications (EN 13242, ASTM C33), forcing operators into costly double-pass screening circuits. Asphalt milling waste introduces additional viscosity complications due to bitumen adhesion, further degrading throughput in conventional crushing trains and increasing operational downtime by 30–40% across seasonal campaigns.
// TECHNICAL SOLUTION
The Impaktor 250 EVO II twin-shaft shredder delivers mobile crusher for construction waste capability at 45 t/h sustained throughput. Its asynchronous crushing kinematics employ counter-rotating shaft profiles with differential torque distribution, enabling the machine to fracture rebar-laden concrete through controlled shear propagation rather than blunt impact. The hydrostatic drive system maintains constant shaft speed under variable resistance profiles — from monolithic concrete slabs to mixed rubble — producing uniform 0–70 mm fractions in a single pass. This eliminates secondary screening, reduces diesel consumption per processed tonne by 22%, and extends cutter tooth service intervals to 800+ operating hours.
// ECONOMIC IMPACT & ROI
Verified 32% total cost of ownership reduction versus jaw-crusher baseline across 12-month operational cycles, driven by single-pass processing, 22% lower fuel burn per tonne, and 800+ hour tooth service intervals. Capital payback in 18 months on a 5-year ROI projection of 68%, factoring in aggregate resale value at €8–12/t and avoided landfill tipping fees of €35–55/t across Central European demolition contracts.
