Definitions

  • the invention relates to a method for operating an asphalt mixing plant and a plant, in particular for carrying out the method according to the preambles of the independent claims.
  • the mineral material to be processed In the production of asphalt in the continuous process (such as in DE 297 00 709 U first, the mineral material to be processed must first be dried and heated before it is mixed with at least one other component, mostly bitumen, to form asphalt. This drying and heating is usually carried out in a drum dryer, in which the mineral material is transported by a stream of hot gas generated therein, wherein it is repeatedly raised and guided in the form of a trickle curtain through the hot gas stream.
  • a first aspect of the invention relates to a method of operating an asphalt mixing plant with a DC or countercurrent tumble dryer for drying and heating the mineral material to be processed into hot mineral material and at least one mixer for mixing the hot mineral material with at least one further component, preferably with a binder , such as bitumen, to asphalt. It is also intended, for example, to mix the hot mineral material with other substances, e.g. with additives, fibers and / or granules of recycled asphalt, with or without the addition of binders.
  • the mineral material to be processed is both "neo-mineral material" in question and asphalt granules / recycled asphalt or other recycled aggregates, or mixtures of such materials.
  • start-up hot mineral material is collected until the exiting hot mineral material formulation is within a certain deviation from the supplied mineral material formulation or equivalent.
  • the hot mineral material emerging from the drum dryer is added in the at least one mixer with the at least one further component Asphalt mixed.
  • This operating state represents the normal operation of the operating phase of the asphalt mixing plant.
  • At least portions of the collected start-up hot-mineral material and the collected drain-hot-mineral material are mixed together in the at least one mixer with the at least one further component to form asphalt.
  • This mode of operation now makes it possible to significantly reduce or even eliminate the amount of broke asphalt or scrap mineral material produced in the case of continuous asphalt mixing plants without having to make the compromise with respect to the recipe known from the prior art.
  • this mode of operation now makes it possible to economically produce even small quantities of quality asphalt with very tight tolerances on continuous plants.
  • the hot mineral material emerging from the drum dryer is mixed in normal operation continuously or batchwise in the at least one mixer with the at least one further component, in one or more Duchlauf- or batch mixers. Subsequently, the entire collected start-up and run-off hot-mineral material during and / or after shutting down the material flow through the drum dryer is mixed batchwise in one or more batches in one or more batch mixers with the at least one further component to asphalt
  • the start-up hot-mineral material and the run-off hot-mineral material are collected in a common container.
  • This is preferably formed as a silo with quadrangular, preferably square cross-section, as these cross-sectional geometry favor mixing or merging of superimposed tarnish hot mineral material and drain hot mineral material during removal, which is particularly advantageous or necessary if this collected hot mineral material is not processed as a batch to asphalt at once.
  • all other cross-sectional geometries and arrangements are also preferred which, upon removal, favor the merging or mixing of the start-up and drain hot-mineral materials.
  • the entire amounts of the collected start-up hot-mineral material and the collected drain-hot-mineral material are mixed all at once in the mixer with the at least one further component. This makes it possible to produce asphalt from the collected start-up and drain hot-mineral material, which compared to the asphalt produced in normal operation has virtually no recipe shift.
  • the amount of mineral material fed to the drum dryer per unit time during the material flow through the drum dryer and the amount of hot mineral material emerging from the drum dryer per unit of time are preferably determined continuously.
  • the emerging hot mineral material is collected as start-up hot mineral material until a certain ratio between the supplied amount and the exiting amount is present or the amounts are identical.
  • the amount per unit time of the mass flow is preferably determined. This makes it possible to keep deliberately within certain limits or virtually eliminate any recipe shifts at the beginning of normal operation in the event that the exiting hot mineral material is collected until the quantities are identical.
  • a second aspect of the invention relates to an asphalt mixing plant, preferably for carrying out the process according to the first aspect of the invention.
  • the plant comprises a drum dryer for drying and heating the mineral material to hot mineral material and at least one mixer for mixing the hot mineral material with at least one further component, in particular with a binder such as bitumen, to asphalt.
  • the system also includes a controller.
  • the system can be driven automatically, in such a way that when starting the material flow through the drum dryer at the beginning of an operating phase of the plant, the starting hot-mineral material emerging from the drum dryer is collected, that after the start of the material flow through the drum dryer in normal operation of the plant the hot mineral material emerging from the drum dryer in which at least one mixer is mixed with the at least one further component to form asphalt, in that, when the material flow through the drum dryer is shut down, at the end of the operating phase of the plant the effluent hot mineral material leaving the drum dryer is collected, and during and / or after the material flow through the drum dryer is shut down, at least portions of the collected start-up hot-mineral material and the collected run-off hot mineral material are mixed together in the at least one mixer with the at least one further component to form asphalt.
  • this is designed such that the hot mineral material emerging from the drum dryer in normal operation can be mixed continuously or batchwise in the at least one mixer with the at least one further component and during and / or after the shutdown of the material flow through the Drum dryer the entire collected start-up and drain hot-mineral material can be mixed batchwise in the at least one mixer with the at least one other component.

  • This is particularly advantageous if the collected hot mineral material is not processed to asphalt in one go.
  • all other cross-sectional geometries and arrangements are also preferred which, upon removal, favor the merging or mixing of the start-up and drain hot-mineral materials. It is also envisaged to provide a container for collecting the start-up hot-mineral material and the drainage-hot-mineral material and to process in each case batches taken from these containers together batchwise in the mixer to form asphalt.
  • the plant is designed such that the collected start-up hot-mineral material and the collected Run-off hot-mineral material can be mixed batchwise in a mixer with the at least one further component.

This makes it possible to produce from the collected start-up and run-off hot-mineral material asphalt, which has virtually no recipe shift compared to the asphalt produced in normal operation.
  • the plant has means for in particular continuous determination of the amount of mineral material fed to the drum dryer per unit time during startup of the material flow and the amount of start-up hot-mineral material emerging from the drum dryer per unit time.
  • the respective mass flows are preferably determined as the amount per unit of time.
  • the system is designed such that it can be automated with the controller driven such that the emerging from the drum dryer hot mineral material is collected as start-up hot mineral material until a certain ratio between the amount supplied and the exiting amount or quantities are identical, and that then the exiting hot mineral material is processed in normal operation to asphalt.
  • This makes it possible to selectively keep or virtually eliminate any recipe offsets at the start of normal operation in the event that the exiting hot mineral material is collected until the incoming and outgoing quantities per unit time or mass flows are identical.
