| 摘要： | The usual service life of an asphalt plant can be from 20-30 years, but a lot of changes can happen in this time such as requirements on formulas and qualities of mixes, or regulations operators have to comply with in order to get an operating licence.However, Benninghoven has a retrofit division that offers an array of upgrades that can allow an existing plant to meet the latest requirements in terms of legislation, as well as advances in mix design.Customers now demand high quality asphalts that require a plant to have specific dosing options, while legislators have tightened up emissions standards and the quantities of RAP fed into the process has been increased. Meanwhile, dust and noise protection regulations required to retain an operating licence have been made stricter, often because residential areas are now located next to an asphalt mixing plant, which would previously have been in a more remote location. In addition, alternative fuels are now sometimes required for the mixing plant burner. |
