The KMA 240(i) is mounted on a flatbed semitrailer and has its own motor station. This mobile design allows the system to be quickly moved to different locations and set up rapidly. Wheel loaders pour a wide variety of unbound raw materials into the proportioning hopper via vibrating grates. Silos or tank trucks supply the plant with binding agents such as cement, bitumen emulsion, or foamed bitumen. A microprocessor-controlled plant control system monitors the addition of raw materials and binding agents into the mixing chamber for high-precision dosing. Here, a heavy-duty twin-shaft pugmill produces a high-quality, homogeneous mix. Finally, the finished mix is smoothly loaded onto the swivel-mounted conveyor, which makes it possible to completely fill even long semitrailers.
Cold recycling can either be carried out in-plant by transporting the material recovered from an existing road to a central warehouse and passing it through a mixing plant, or in-place/in-situ using a cold recycler.
In the in-place/in-situ mixing process, a cold recycler granulates the existing pavement and homogeneously mixes in the binding agent and water.
In the in-plant mixing process, RAP and crushed rock are transported to a mixing plant near the construction site.
All WIRTGEN machines feature a built-in, high-quality machine control system. The fact that the majority of its software is developed in-house plays a key role in this regard – WIRTGEN has placed a special focus on ongoing development, thus significantly increasing the operational reliability of its machines. Many years of experience in software and hardware development also makes it possible to achieve more flexible and sophisticated machine functionality in terms of the range of applications and individual customer requirements.
