WIRTGEN KMA240i — MOBILE COLD RECYCLING MIXING PLANT

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.

RECIPE FOR SUCCESS FOR HARD-WEARING ROAD SURFACES

The KMA 240(i) cold recycling mixing plant produces cold mix that can be paved immediately for a wide variety of construction projects, such as cement-treated base (CTB) layers for freeways. Due to the particularly generous, continuous addition of cement, enormous daily outputs can be achieved with maximum precision. In addition to CTB and RCC (roller-compacted concrete), cold mix can be produced that is stabilized with bitumen emulsion or foamed bitumen (BSM). The road surfaces produced from these high-quality cold mixes then stand out due to their excellent bearing capacity, resistance to deformation, and long service life.

ECO-FRIENDLY TECHNOLOGY

The highly mobile cold recycling mixing plant can be easily transported from site to site and quickly set up in the near vicinity. This saves time, truck capacity, and is also extremely environmentally friendly, making it possible to achieve up to 60% fewer CO2 emissions thanks to cold processing, a 90% reduction in transport volumes, and up to 50% lower total costs compared to conventional construction methods – in other.

A WIDE RANGE OF APPLICATIONS

A particularly impressive feature of the KMA 240(i) is its ability to process a variety of different, non-cohesive raw materials. As a result, mixes can be produced from a wide variety of virgin construction materials, reclaimed recycled materials, and binding agents. Virgin construction materials include raw materials such as mixtures of sand, gravel, or crushed stone. Recycled construction materials include milled material and all other materials reclaimed from old road surfaces or processed rubble, e.g. RCL (recycled gravel) or asphalt milled material. Cement, bitumen emulsion, or foamed bitumen supplied by silo or tanker trucks are the most suitable binding agents. The required quantity of binding agents and aggregates is precisely determined by preliminary tests in the road construction laboratory. Based on these specifications, the plant then prepares the homogeneous mix with the desired properties. Foamed bitumen for the construction of durable BSM base layers is an extremely cost-effective binding agent, as the quantities added are extremely low.

COMPACT TRANSPORT DIMENSIONS

The well-engineered design allows the compact system to be easily and safely “packed up” onto a flatbed truck trailer and transported to the next site, saving both time and money. All you need to do is swivel in the discharge conveyor and operator’s cabin, move the cement charging auger to the transport position, and then hitch up the plant. A common truck is completely sufficient for transporting the plant as all of its connectors are standardized. The compact transport dimensions and low overall weight of the KMA 240 (i) comply with international traffic regulations, eliminating the time-consuming process of applying for special permits in most locations.

RAPID SETUP AND DISASSEMBLY

Setup and disassembly can be carried out quickly and easily without special tools – stable supports are extended and manually unfolded to ensure the plant stands securely. In addition, hydraulically powered, continuously extendable supports are mounted under the water tank and between the axles to support the machine’s weight. The hydraulic supports can be used to precisely level the plant. Fold-out, stable flaps used to set up the loading ramp protect the free space under the plant. The only thing left to do is to swing out the operator’s cabin and discharge conveyor at the push of a button and connect the cement charging auger via quick-release connectors – done!

SMALL FOOTPRINT AND FLEXIBLE CONNECTION OPTIONS

Flexibility was a top priority when designing the mobile mixing plant. This is why connections for water, emulsion, and bitumen are found in a number of locations. The same applies to the cement – whether via a stationary silo on the left or right or fed by hand, anything is possible. This gives you plenty of freedom when determining where to place the KMA 240(i). After all, the plant’s direct proximity to the job site or materials warehouse offers an unbeatable advantage in terms of time, cost, and energy savings.

STAND-ALONE JOB SITE OPERATION

The plant’s own diesel engine not only ensures that it isn’t dependent on the public power grid and guarantees an exceptionally high daily output, but can also be operated extremely efficiently for up to two days on a single tank of fuel.
