Description
sammentreffen von Mineralkomponenten und Füllerkomponente durch Wärmeaustausch die gewünschte Mischungstemperatur des fertigen Gußasphalts zu erreichen. Das gleiche gilt für den Fall, daß die Bindemittelkomponente kalt zugegeben wird und durch S Wärmeabgabe der Mineralkomponente aufgeschmolzen und verflüssigt wird.meeting of mineral components and filler components to achieve the desired mixing temperature of the finished mastic asphalt through heat exchange. The same applies in the event that the binder component is added cold and S The heat given off by the mineral component is melted and liquefied.
Die Ausübung des Verfahrens soll nachstehend durch ein Beispiel näher erläutert werden:The execution of the procedure is to be explained in more detail below by means of an example:
Es wird von der Annahme ausgegangen, daß pro Charge 4 t Gußasphalt entsprechend nachstehender Rezeptur hergestellt werden sollen:It is assumed that 4 tons of mastic asphalt per batch, corresponding to the following Recipe to be produced:
Grabsand, 0/2 mm.. 20%
Brechsand, 0/2 mm 20 %Grave sand, 0/2 mm .. 20%
Crushed sand, 0/2 mm 20%
Splitt, 3/8 mm 30%Grit, 3/8 mm 30%
Füller 22%Filler 22%
Bitumen HVB 85/95 8%

100%
entsprechend 800 kg entsprechend 800 kg entsprechend 1200 kg entsprechend 880 kg entsprechend 320 kg 4000 kgcorresponding to 800 kg corresponding to 800 kg corresponding to 1200 kg corresponding to 880 kg corresponding to 320 kg 4000 kg
Die einzelnen Mineralkomponenten werden in einem Trommeltrockner üblicher Bauart auf etwa 280 bis 300° C nacheinander erhitzt, und zwar in solchen Mengen, daß die einzelnen Taschen eines gut isolierten Rundsilos vorzugsweise im Interesse der Einstellung geringster Abstrahlverluste ganz gefüllt werden können.The individual mineral components are reduced to around 280 in a conventional drum dryer Heated up to 300 ° C in succession, in such amounts that the individual pockets of one are well insulated Round silos should preferably be completely filled in the interest of setting the lowest possible radiation losses be able.
Dies ist deshalb wichtig, weil das Silo bereits am Vortag gefüllt werden und- dadurch am anderen Morgen unmittelbar mit dem Mischprozeß begonnen werden kann.This is important because the silo is already filled the day before, and thus on the other The mixing process can begin immediately tomorrow.
Der Transport des Minerals vom Trommeltrockner zum Silo erfolgt dabei im allgemeinen über einen sogenannten Heißelevator.The mineral is generally transported from the drum dryer to the silo via a so-called hot elevator.
Die Beschickung des Silos kann auch unmittelbar durch den Auslauf des Trommeltrockners dergestalt durchgeführt werden, daß der Trommeltrockner so angeordnet wird, daß dessen Auslauf unmittelbar in den Siloeinlauf einmündet.The silo can also be fed directly through the outlet of the drum dryer be carried out that the drum dryer is arranged so that its outlet is directly in opens into the silo inlet.
Dem gut vorgeheizten Mischer wird nun der Bindemittelanteil (8%, 320 kg) durch ein hier nicht beschriebenes separates Bindemittelzuteilgerät insgesamt zugeführt.The proportion of binder (8%, 320 kg) is now transferred to the well-preheated mixer using a method not described here separate binder metering device supplied as a whole.
Die zweite Zuteilcharge setzt sich aus etwa je 25% (je 400 kg) der beiden Sandkomponenten und 15% (132 kg) der Füllerkomponente zusammen, während sich der dritte Zuteilcharge aus 50% (600 kg) der Splittkomponente und weiteren 30% (264 kg) der Füllerkomponente aufbaut. Die vierte Zuteilcharge setzt sich aus dem Rest der Sandkomponente (50%, 800 kg) und 15% (132 kg) Füller zusammen.The second allocation batch consists of around 25% (400 kg each) of the two sand components and 15% (132 kg) of the filler component together, while the third allocation batch consists of 50% (600 kg) of the Grit component and another 30% (264 kg) of the filler component builds up. The fourth allocation batch consists of the rest of the sand component (50%, 800 kg) and 15% (132 kg) filler.
Als fünfte Zuteilcharge werden der Rest der Splittkomponente (50%, 600 kg) und der Füllerkomporiente (40%, 352 kg) zugegeben.The rest of the chippings (50%, 600 kg) and the filler components are used as the fifth feed batch (40%, 352 kg) added.
DieZugabe kann beispielsweise über einen unter den eng zusammengefaßten Ausläufen der einzelnen Silotaschen angeordneten Kübelaufzug, der mit einer Bodenwaage kombiniert ist, erfolgen, wobei es sich empfiehlt, die Kübelaufzugsbahn durch einen Isolierschacht zu umkleiden.The addition can, for example, via one of the narrowly grouped outlets of the individual silo pockets arranged bucket elevator, which is combined with a floor scale, take place, whereby it is recommends lining the bucket elevator with an insulating shaft.
Zur Aufgabe für das Mineral,, den Füller und das Bindemittel werden bei dieser beispielsweisen Durchführung des Verfahrens etwa 6 bis 7 Minuten benötigt. Nach einer kurzen Nachmischzeit von etwa 1 Minute kann die Entleerung des Mischers eingeleitet werden, so daß nach etwa 12 Minuten die Beschikkung des Mischers erneut erfolgen kann.In this exemplary implementation, the task for the mineral, the filler and the binding agent the procedure takes about 6 to 7 minutes. After a short mixing time of around Emptying of the mixer can be initiated for 1 minute, so that charging takes place after about 12 minutes the mixer can be done again.
Mit der damit erzielten Leistung von 20 t/h Gußasphalt wird der bei Gußasphalt-Unternehmen mittlerer Größe während der Zeit von 5.00 bis 9.00 Uhr anfallende Frühbedarf von etwa 601, was ungefähr der Füllung von 15 Kochern entspricht, gedeckt, ohne daß kostspielige Nachtschichten gefahren werden müssen.With the achieved output of 20 t / h mastic asphalt, that of mastic asphalt companies is medium Size during the time between 5:00 and 9:00 a.m. early demand of about 601, which is approximately corresponds to the filling of 15 cookers, covered without having to work expensive night shifts have to.
Selbstverständlich ist das oben beschriebene Verfahren nach ,der Erfindung nicht allein auf die Aufbereitung von Gußasphalt beschränkt, sondern läßt sich ebenso auch für die Herstellung anderer verstreich- oder einbaufähiger bituminöser Massen anwenden. It goes without saying that the method described above according to the invention is not limited to processing limited by mastic asphalt, but can also be spread for the production of other or use bituminous compounds that can be installed.
