Wirtgen KMA 240i

New Wirtgen KMA 240i Mixer for Sale

The mobile cold recycling mixing plant is simple to transport and quick to set up in the direct vicinity of the operation site. The robust twin-shaft compulsory mixer achieves high mixing performance levels. Microprocessor-controlled injection systems for the addition of a wide range of binding agents ensure that the materials are mixed precisely to formula. The slewing discharge conveyor with its wide range of motion enables the processed cold mix to be stockpiled or continually loaded onto transport vehicles.

Effective and environmentally friendly mix preparation

• The KMA 240i high-performance cold recycling mixing plant is designed for the resource-friendly production of high-quality mix at a massive mixing capacity of more than 265 t (240 tons) per hour.
• The KMA 240i 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.
