A mixing plant that comes to the job site Mobile cold recycling mixing plant KMA 220

The mobile mixing plant with mega capacity Let’s be honest: Innumerable truck journeys between the mixing plant and remote job sites are not only very time-consuming, they’re also a burden on your budget. Wirtgen engineers have now designed the ideal solution to this problem with the mobile cold recycling mixing plant KMA 220. The plant can easily be transported from one job site to the next and is quickly assembled in the immediate vicinity of the site. This saves time and truck capacities, and is also a highly environmentally friendly approach. What’s more, the KMA 220 impresses with...

2 // 3 Cold mixes can be produced from various construction materials and can be used for top-quality construction projects. The plant’s own diesel engine guarantees independence from public power supply. Assembly of the KMA 220 is flexible and can be tailored to optimally suit the conditions on the job site. The plant is transported by means of a standard tractor vehicle. Short haulage distances – big performance … and ready for transport just a little later The mobile mixing plant was fully operational just a minute ago …

A large variety of mixing options satisfies all requirements A particularly noteworthy feature of the KMA 220 is its capability to mix many different unbound source materials. The plant can produce cold mixes from a large variety of new aggregate mixtures, reclaimed recycling materials and binding agents. Suitable binding agents are cement, bitumen emulsion or foamed bitumen, which are delivered in special tanker trucks. The plant uses them to produce a homogeneous mix with the desired material properties. Mix different construction materials in accordance with quality requirements

4 // 5 Milled material or any other construction materials recovered from old road pavements are suitable for recycling in an environmentally friendly manner. The precise quantities of binding agents and aggregate to be added are determined by preliminary investigations in a road laboratory. Hot foamed bitumen is ideally suited for mixing with cold and wet construction materials. Foamed bitumen is a highly economical binding agent because the quantities that need to be added are very small. Materials and material combinations suitable for use Broad range of different construction materials...

It may look small – but its products are the measure of all things At first glance, the KMA 220 appears comparatively small and inferior in performance to the stationary hot mixing plants. Quite the opposite is true, however: The compact plant possesses ample power. Driven by a powerful diesel engine, it produces an astonishing 220 tons/hour of high-quality mix. This mixing performance surpasses even that of many large stationary plants. Performance is not all that counts, however. A continuous supply of material to the site is also of paramount importance. This is guaranteed by the KMA...

6 // 7 When operating at a mixing capacity of 200 t/h, one truck load of 20 tons of cold recycling mix is produced every 6 minutes. Truly impressive: This quantity enables a 150 m long, 4 m wide and 15 cm high base layer to be paved per hour. The plant’s continuous production guarantees that even large road pavers are continuously supplied with cold mix. A powerful flow mixer ensures that all construction materials are mixed homogeneously. Unlimited mix production Trucks keep changing “on the fly”, making short work of any construction project at a mixing capacity of 200 t/h The discharge...

Mobility is a valuable asset – for the environment, too The KMA 220 is a mixing plant that comes to the job site, which makes long transport distances from the production site of the mix to the paving site and back a thing of the past. It enables you to save time and in particular costs, reducing expensive truck journeys and fuel consumption to a minimum. The environment benefits as well: The reclaimed material can be reused completely, which helps to save natural resources. And what’s more, the source materials need neither be dried nor heated to be suitable for producing the new mix....

8 // 9 Mix production in the immediate neighbourhood of the site or stocking location facilitates the overall management of the construction project. An important contribution to reducing environmental impacts: Short truck haulage distances result in reduced fuel consumption and CO2 emission. A complete reuse of the reclaimed asphalt material guarantees maximum economic efficiency. The mobile plant is equipped with an energy-saving diesel engine that is capable of working up to two full days with just one tank filling. Invest to save money This project was completed very quickly because mix...

The KMA 220 reduces its size for transport purposes One of the KMA 220’s hallmarks is, of course, its unparalleled mobility. Its ingenious design enables the plant to simply be “packed up” and moved to the next job location quickly and efficiently. All that needs to be done is to swing in the cement auger, discharge conveyor and operator’s cabin, and to connect the plant to the tractor vehicle. A standard tractor vehicle is fully sufficient for transport as the plant is equipped with standardized connections. Individual components need not be transported separately. Small goes farther than...

10 // 11 The complete mixing plant is securely fastened on the low-bed trailer. Reversing lights attached to the operator’s cabin ensure safety on the road. The plant’s transport dimensions adhere to the international guidelines for road traffic. A special permit is not required. Mobility is a real ace The KMA 220 sets out, folded into a compact package Easily accessible plug-and-socket connections enable simple connection to transport vehicle

Assembled in no time at all Another highlight is the plant’s fast assembly and disassembly. The KMA 220 has scarcely arrived on the job location before it is ready to take up production. Sturdy supports are folded out manually, thus ensuring the plant’s stability. Hydraulically operated supports are additionally mounted in the areas below the water tank and between the axles, carrying the plant’s weight. All that has to be done now is swing out the operator’s cabin, discharge conveyor and cement auger at the push of a button, and here goes! You think the plant needs a foundation? It’s not...
