System for preparation of an asphalt mixture comprising paraffin

摘要

A system for preparing a chemical mixture, in particular an asphalt mixture having a paraffin fraction has a Paraffinschmelz- and -dosiervorrichtung (33) having a dosing unit for the promotion of an adjustable quantity of paraffin from a paraffin tank (17) in a material component of the mixture, an input device for providing a desired paraffin content in the mixture, and a control and / or regulating device for adjusting the -dosiervorrichtung to be dispensed from the Paraffinschmelz- and paraffin dose in dependence of the inwardly conveyed amount of the material component of the mixture and the paraffin content entered on. This enables a volume and temperature exact dosage paraffin. Through early paraffin adding in a binder component, there is considerable potential for energy savings in the production of asphalt. A fast and flexible use at different places need is achieved by a modular design of the Paraffinschmelz- and -dosiervorrichtung.
