 Asphalt & Bitumen
 Renewing existing mixing
plants by retrofitting Working in partnership to renew old technology
The usual service life of asphalt mixing plants is easily twenty to thirty years – if not longer. Over this unbelievably long period, a lot can change in the world – requirements on formulas and qualities of mixes, for example, and often the official regulations operators have to comply with in order to get an operating licence. Benninghoven accompanies customers and users through all the challenges of modernization – with its very own retrofit division.
Parameters which may change during the working life of an asphalt mixing plant
Customers demand new, higher-quality asphalts which require the plant to have specific dosing options. Legislators tighten up emissions standards. The proportion of RAP fed to the process is increased, reducing raw material costs –but only for operators with the appropriate technology. Dust and noise protection regulations (Germany’s “TA-Luft” and “TA-Lärm”, for example) required to retain an operating licence are made stricter – often because residential areas expand right up to the asphalt mixing plant which used to be in an isolated position. Alternative fuels are required for the mixing plant burner.
Seven good reasons for a Benninghoven retrofit
1 State of the art: bringing the asphalt mixing plant up to the current state of the art.
2 Protecting your existing site: ensuring that the site retains its operating licence.
3 Sustainability and economy: replacement of components and integration of recycling technologies pay for themselves.
4 Optimization and efficiency: modern control technology from Benninghoven improves plant performance.
5 Win-win: updating the plant can also be used as an opportunity to satisfy individual requirements – serial production solutions have already been developed from customer ideas.
6 Improve instead of repair: the recommendation from Benninghoven experts will leave plants in a better state after the retrofit than before it.
7 All makes: Benninghoven retrofit solutions are also possible for plants from other manufacturers.
Teamwork: low-loaders transport the new dryer drum to its final position. The Guggenberger crew and the Benninghoven fitters complement one another perfectly in this process.
