Cold planers

Cold planers: The future of cold planing is here now.

Thanks to their compact design and excellent visibility, BOMAG cold planers are ideally suited for selective milling of roads and surfaces in tight working conditions.

But BOMAG road planers can also demonstrate their strengths to the full on motorways or airport runways. In recent years, BOMAG has continuously set new technical standards in terms of maintenance friendliness and milling technology for today’s high-performance milling machines.

BOMAG cold planers - optimised for road reconstruction.

Cold milling is usually the first step in road reconstruction: asphalt, concrete or gravel layers are removed layer by layer through selective milling. The road surface is removed by a rotor equipped with many round shank picks. This takes place in a closed milling chamber, the road milling machine’s so-called milling box. The milled material can be immediately loaded onto a truck via conveyor belt. After cold planing, a sweeper removes the last residues of milled material from the milling track. The cleaned track provides a profiled base for the subsequent installation of binder and surface layers of uniform thickness. Cold milling, or asphalt milling, replaced the technique of hot milling in the late 1970s, significantly reducing energy requirements and costs. Today, BOMAG road milling machines can be used for various maintenance tasks, such as milling off deformations, removing ruts on longer sections and renewing the road surface over the full width, followed by the installation of surface and binder courses.

Asphalt milling machines - equipped with state-of-the-art milling and levelling technology.

BOMAG offers cold planers in various classes. Small cold planers with a working width from 0.3 m to 1.0 m are offered as rear loaders. The compact planer class includes widths of 1.0 m, 1.2 m and 1.3 m, designed as front loaders. BOMAG also has large cold planers in its product portfolio, with working widths ranging from 1.5 m to 2.2 m for the largest cold milling machines. The large asphalt milling machines are typically operated by a driver and a ground person, who is responsible, among other things, for the quality of the milled surface.The milling depth on asphalt milling machines is adjusted with lifting columns. Highly precise sensors determine the position of the reference surface. The cold planer’s discharge conveyor can be swivelled to the side for flexible loading on all BOMAG variants.

Cold planers – with intelligent technology.

All BOMAG cold planers have a water reservoir that feeds a water spraying system. The water is used to cool the cutting tools during the milling process, reducing their wear. In addition, the spray mist already binds some of the dust generated in the milling box.

ION DUST SHIELD - available as an option for compact and large planers.

BOMAG road milling machines with ION DUST SHIELD can do even more: the technology developed in-house reduces fine dust emissions by over 80%. Instead of filtering fine dust, the ION DUST SHIELD technology converts it into coarse dust by means of an electrical charge.

A decisive factor for an asphalt milling machine’s performance is the combination of the cutting tools and the holder system.

What is required is nothing less than maximum milling performance with minimum cutting tool wear. BOMAG relies on optimised milling drum geometry and a long service life for all components in its road planers. This not only results in longer operating times for the milling drums, but also ensures smoother operation and thus low-vibration milling. The outcome: reduced service times and, consequently, lower operating costs.
