New chilly recycling mixing plant from Wirtgen offers sustainable recycling near the job web site

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. 

With this answer, Wirtgen is making a significant contribution to making sure that recycled building supplies are returned to the highway building cycle within the type of high-quality combine. The brand new roads and industrial areas constructed on this method function a excessive bearing capability, resistance to deformation, and lengthy service life.

The mixing plant produces combine/chilly combine that may be paved instantly and is ideally suited to producing several types of sure base layers. 

Along with cement-treated base layers (CTB) and roller-compacted concrete (RCC), the machine can be used to supply bituminous sure base layers (with emulsion or foamed bitumen). The completely different mixes/chilly mixes can be utilized for a variety of functions, together with freeway building, highway and path building, and the development of parking tons or industrial areas. 

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 completely 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 modern cement metering system with computerized 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. Because of an effectively insulated housing, it additionally emits little or no noise. The engine could 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. Consequently, sections of a cement-treated or bituminous sure base layer with a working width of 4 meters and a paving thickness of 15 cm could be accomplished over a size of 1400 meters each day.

Larger mixing capacities with completely different enter supplies

The KMA 240(i) is ready 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 doable to supply mixes/chilly mixes from all kinds of recent granular mixtures or numerous milled supplies and binding brokers. 

Asphalt milled materials, all different non-cohesive supplies reclaimed from outdated highway surfaces, and supplies from RC processing can all be used to construct new highway surfaces in an environmentally pleasant method. The flexibility to fully reuse the fabric ends in excessive CO2 and vitality financial savings with minimal building prices and undertaking durations.

Sooner combine preparation due to optimized metering

Silos or tank vans provide the chilly recycling mixing plant with binding brokers, corresponding to sizzling bitumen, bitumen emulsion, and cement. The exact metering of the enter supplies and binding brokers, the ratio of which is decided upfront by preliminary assessments within the highway building laboratory, is monitored by a confirmed microprocessor management system. 

The KMA 240(i) ideally masses the brand new, homogeneous combine immediately onto vans or deposits it constantly on a stockpile. Loading or depositing could be carried out in an especially versatile method due to the discharge conveyor that may swing 55° to both facet.
