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.
