How can we help?
Description
Mix preparation on construction site
-
The mobile concept of the cold recycling mixing plant means the machine can be used in the direct vicinity of the operation site, saving both money and time.
-
The robust twin-shaft pugmill mixer exhibits high levels of mixing performance with consistent quality.
-
Mixing precisely to formula is made possible thanks to the use of accurate, microprocessor-controlled spraying units for adding various binding agents.
-
The slewing discharge conveyor enables the processed material to either be stockpiled or continuously loaded on to trucks.
-
Solid fold-out or rather extendable supports ensure the machine stands firm and enable it to be quickly and precisely aligned.

Features
- 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.

- Cold recycling with the KMA: 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.
