BOMAG at the bauma 2016: Outdoor stand FS. 1009
BOMAG cold planers: Reduction in fine particulates of over 80%

It is BOMAG's explicit goal to develop machines that reduce fine particulates in road recycling as much as possible. Thanks to the collaboration with the Dutch company Environmental Nano Solutions (ENS Europe BV), which is committed to developing product solutions that combat the problem of fine particulates, BOMAG has achieved a partial victory against fine dust. At the bauma 2016, BOMAG is presenting the new joint development for dust extraction in compact and large milling machines for the first time at exhibition stand FS. 1009. The institute for hazardous materials research (IGF) of the Ruhr University in Bochum confirmed with a scientific measurement that, using this solution, over 80% of fine particulates are bound electrostatically and rendered harmless.


Boppard, 11.04.2016: On account of Stuttgart's topographically unfavourable location in a valley basin, the city frequently has to sound the fine particulates alarm. However, exposure to harmful fine dust is increasing in all urban areas. At a diameter of less than 10 µm, it is inhaled and, if it is particularly fine (diameter below 2.5 µm), it can even be respirable. Fine particulates are found not only in diesel soot, but also in heating exhaust fumes and the most diverse of abrasions.

Fine particulates are also produced during the cold milling of road surfaces. In order to render these harmless at source, BOMAG has developed a solution jointly with ENS, and had the results confirmed scientifically with measurements conducted by the institute for hazardous materials research (IGF) of the Ruhr University in Bochum. In future, BOMAG will offer this technology for its milling machines of more than one metre working width, and will present this technical solution for the first time at the bauma 2016 at their stand in the outdoor area FS. 1009.

Small box, big impact

The new system is mounted in a small housing on the conveyor belt. The dust particles, which are transported by dust extraction through an electric field become positively charged and are attracted by an electrode on the other side of the housing. There the dust particles clump together and form flakes, which can no longer be inhaled. The flocculated and thus bonded particulate dust is then simply discharged by the conveyor belt. Measurements by IGF confirm that over 80% of particulate matter can be removed with this method. Without a dust extraction system, the ratio of engine and milling process in terms of particulate emissions is about 1:100. With the dust extraction system developed by ENS and BOMAG, the ratio is reduced to approx. 1:20.

Jonathan Stringham, manager of milling at BOMAG: "This new development considerably reduces the burden of road recycling - for construction plant operators as well as for residents. BOMAG is the only manufacturer to offer this solution. It brings us a great deal closer to our goal of the sustainable construction site."
