The KMA 220 / KMA 220i is mounted on a flatbed semitrailer and equipped with an independent powerstation. The mobile concept enables the plant to be relocated to different operating sites quickly and set up in next to no time. Wheeled loaders empty all kinds of unbound source materials into the proportioning hopper via vibrating grids. Silos and / or tankers supply the plant with binding agents such as cement, bitumen emulsion or foamed bitumen. For high-precision metering, a microprocessor-controlled system monitors the addition of source materials and binding agents into the mixing chamber. A heavy-duty twin-shaft compulsory mixer produces a homogeneous construction material of high quality. In a final step, the recycled mix is simply discharged via the slewing belt conveyor which enables even long semitrailers to be loaded to full capacity.
Cold recycling can be achieved either in-plant by hauling material recovered from an existing road to a central depot where it is fed through a mixing unit, or in-place using a recycling machine.
When mixing in-place / in-situ, a cold recycler granulates the existing pavement while mixing in binders and water homogeneously at the same time.
When mixing in-plant, reclaimed asphalt pavement and crushed stone are transported to a mixing plant located in the vicinity of the construction site.
WIRTGEN machines are fitted with a machine control system of the highest quality, in which the large proportion of software developed in-house plays the decisive role. WIRTGEN puts a special focus on continuous improvement, which has the added effect of significantly increasing the operational reliability of the machines. In addition, many years of experience in software and hardware development allow for higher and more flexible machine functionality in terms of applications and meeting specific customer requirements.
