Wirtgen’s new chilly recycling mixing plant brings sustainable recycling near the job web site


With its new high-performance resolution, Wirtgen is making a serious contribution to making sure that recycled building supplies are returned to the street building cycle within the type of high-quality combine. 

The KMA 240(i) cell chilly recycling mixing plant is able to processing 240 tons of combine from a wide range of building supplies per hour in an environmentally pleasant method. The brand new roads and industrial areas constructed on this approach stand out for his or her excessive bearing capability, resistance to deformation, and lengthy service life.

Recipe for achievement for hard-wearing street surfaces 

The KMA 240(i) chilly recycling mixing plant produces combine/chilly combine that may be paved instantly and is ideally suited to producing various kinds of sure base layers. Along with cement-treated base layers (CTB) and roller-compacted concrete (RCC), the machine will also be used to supply bituminous sure base layers (with emulsion or foamed bitumen). The totally different chilly mixes can be utilized for a variety of functions, together with freeway building, street and path building, and the development of parking tons or industrial areas.

KMA 240(i): 20 tons of chilly recycled materials each 5 minutes 

The chilly recycling mixing plant is mounted on a flatbed semitrailer and has its personal engine unit. This cell design permits the system to be flexibly moved to totally different areas and arrange quickly. In its new chilly recycling mixing plant, Wirtgen has mixed the benefits of its earlier mannequin, the KMA 220(i), with improved mixing efficiency and an revolutionary cement metering system with automated self-calibration by way of static weighing.

The highly effective six-cylinder diesel engine is designed for the machine’s excessive mixing capability of as much as 240 t/h. Due to an effectively insulated housing, it additionally emits little or no noise. The engine might be operated economically for as much as two days on one tankful. Its low emission values additionally enable it for use in city areas.

With a capability of 240 t/h, the machine produces a full truckload of 20 tons of combine each 5 minutes. In consequence, sections of a cement-treated or bituminous sure base layer with a working width of 4 meters and a paving thickness of 15 cm might be accomplished over a size of 1400 meters every single day.

Greater mixing capacities with totally different enter supplies 

The KMA 240(i) impresses with its capability to course of a big number of non-cohesive base supplies, which wheel loaders feed to the plant’s hopper by way of vibrating grids. This makes it attainable to supply chilly mixes from all kinds of latest granular mixtures or varied milled supplies and binding brokers. Asphalt milled materials, all different non-cohesive supplies reclaimed from outdated street surfaces, and supplies from RC processing can all be used to construct new street surfaces in an environmentally pleasant method. The power to fully reuse the fabric ends in excessive CO₂ and power financial savings with minimal building prices and challenge intervals.

Sooner combine preparation because of optimized metering 

Silos or tank vehicles provide the chilly recycling mixing plant with binding brokers, comparable to scorching bitumen, bitumen emulsion, and cement. The exact metering of the enter supplies and binding brokers, the ratio of which is decided prematurely by preliminary checks within the street building laboratory, is monitored by a confirmed microprocessor management system. The KMA 240(i) ideally hundreds the brand new, homogeneous combine straight onto vehicles or deposits it repeatedly on a stockpile. Loading or depositing might be carried out in a particularly versatile method because of the discharge conveyor that may swing 55° to both aspect.

Chilly in-plant recycling: environmentally pleasant, cost-effective and versatile 

Chilly recycling expertise from Wirtgen is an environmentally pleasant and on the similar time cost-effective rehabilitation technique that may be carried out both in place – wherein case the broken pavement is eliminated by a cell recycling practice, processed on web site, and instantly repaved – or in plant.

If the blending plant is situated too far-off or the job web site would not meet the logistical necessities wanted to hold out the whole recycling course of in a single go, chilly in-plant recycling is commonly the right resolution. This technique includes establishing the KMA cell chilly recycling mixing plant within the speedy neighborhood of the job web site. This protects time, truck capability, and can also be extraordinarily environmentally pleasant, making it attainable to attain as much as 70 p.c fewer CO₂ emissions by means of chilly processing, a 90 p.c discount in transport volumes, and as much as 40 p.c decrease building prices. Moreover, the high-quality constructing supplies are fully reused.
