Abstract

Dry mortar mix based on REA-gypsum and moist additives, made in heated mixing or oven units by a process in which the REA-gypsum is calcined, the additives are dried and the mixt. is homogenised simultaneously. The REA-gypsum is converted into the hemi-hydrate, anhydrite or gypsum cement. The starting materials may also include conventional binders such as white fine lime, filter ash and filter dust which favour the drying process by binding water. USE/ADVANTAGE - The process in which the components are processed simultaneously and homogenised gives higher quality dry mortar mixes than are obtd. by mixing separately-processed components, and allows prodn. of mortar mixes using local raw materials, thus avoiding the cost of transporting large amts. of material from prodn. site to usage site.

Description

Die Erfindung betrifft ein Trockenmörtelsystem, das die gleich­ zeitige Aufbereitung von Bindemitteln, vornehmlich REA-Gips, und das Trocknen von Zuschlagstoffen zum Inhalt hat. Die einzel­ nen Komponenten werden gemeinsam in eine Aufbereitungsanlage gegeben, die das Material durch vorzugsweise indirekte Befeuerung umwandelt und trocknet.The invention relates to a dry mortar system that is the same early preparation of binders, primarily REA gypsum, and involves drying aggregates. The single Components are put together in a processing plant given the material by preferably indirect firing converts and dries.

Die Bewegung des Materials erfolgt durch die Bewegung des Dreh­ rohrofens oder mittels geeigneter Umwälzanlagen in aufheizbaren Mischern.The movement of the material takes place through the movement of the rotation tube furnace or by means of suitable circulation systems in heatable Mixers.

Die Wahl des Aufbereitungsaggregates folgt in Abhängigkeit des angestrebten Produktes und der täglichen Ausbringung.The choice of the treatment unit depends on the desired product and daily application.

Es hat sich gezeigt, daß die Produktqualität der gemeinsamen Verarbeitung der Komponenten besser ist als die getrennte Auf­ bereitung des Bindemittels, als die getrennte Trocknung des Zuschlagstoffes und als die spätere Zusammenführung der einzelnen Komponenten.It has been shown that the product quality of the common Processing of the components is better than the separate on preparation of the binder as the separate drying of the Aggregate and as the later merging of the individual Components.

Die während der Aufbereitung anfallenden Wasserdampfmengen und sonstige flüchtigen Bestandteile werden kondensiert, dem Prozeß wieder zugeführt oder mittels Abscheider umweltverträglich behandelt.The amounts of water vapor and other volatile constituents are condensed, the process fed back or environmentally friendly using a separator treated.

Die Prozeßsteuerung sieht vor, daß die Krefelder Systemtrocken­ mörtel nur entsprechend den Rezeptvorgaben gefertigt werden können. Durch diese Sicherung wird gewährleistet, daß stets nur gleichbleibende und DIN-verträgliche Qualitäten produzierbar sind.The process control provides that the Krefeld system dry mortar can only be manufactured according to the recipe specifications can. This backup ensures that always only consistent and DIN compatible qualities can be produced are.

Das Anlagensystem funktioniert bei Tagesleistungen von 5 Tonnen aufwärts, sodaß örtliche Zuschlagstoffe, örtliche Bindemittel und örtliche Verarbeitungsgewohnheiten berücksichtigt werden können. Die Stoffe können während Schlechtwetterperioden auf Vorrat gefertigt werden und sparen hohe Kosten für überregionale Warenbewegungen ein.The system works with a daily output of 5 tons upwards, so that local aggregates, local binders and local processing habits are taken into account can. The fabrics can appear during bad weather periods Be made in stock and save high costs for national Goods movements.
