Effective and environmentally friendly mix preparation

  • The KMA 240 high-performance cold recycling mixing plant is designed for the resource-friendly production of high-quality mix at a enormous mixing capacity of more than 240 tons per hour.
  • The KMA 240 is capable of processing a wide variety of base materials, such as recycled construction materials, milled asphalt material, demolished concrete, or virgin road construction materials, as well as binding agents, such as cement, bitumen emulsion, or foamed bitumen.
  • The mix is ideally suited for any type of construction project, e.g. for cement-treated or long-lasting bituminous base layers in road and path construction, parking lots, and industrial areas.
  • The mobile design of the cold recycling mixing plant allows the machine to be transported directly to the job site, saving both time and money.
  • The ability to completely recycle materials in combination with cold processing results in significant CO2 and energy savings with minimal construction costs and project periods.

Cold recycling with the KMA

The KMA 240(i) 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.

Mixing procedures

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.
