Abstract

Production of ceramic products comprises forming a material mixture made from clay and/or loam with the addition of animal feed as porosity agent; forming a blank using an extruder; cutting into individual lengths of brick; drying; and calcining. An Independent claim is also included for a mixture for the manufacture of ceramic products comprising a base building material made from clay and/or loam mixture, animal feed as a porosity agent and optionally additives. Preferred Features: The animal feed is used in an amount of maximum 5 wt.%. The animal feed is used as a fuel for ceramic ovens.

Description

Die Erfindung betrifft ein Verfahren und eine Mischung zur Herstellung von Produkten der keramischen Industrie, insbesondere von Mauerziegeln, gemäß Oberbegriff des An­ spruchs 1.The invention relates to a method and a mixture for the manufacture of products of the ceramic industry, especially of bricks, according to the preamble of the An saying 1.

Moderne Mauerziegel zeichnen sich durch eine Vielzahl po­ sitiver technischer Eigenschaften aus, mit denen sie sich entscheidend von anderen Baustoffen absetzen. Die Ziegelei­ genschaften werden durch die eingesetzte Verfahrenstechnik, insbesondere aber durch die verwendeten Rohstoffe bestimmt. Mit der Auswahl geeigneter Porosierungsmittel und Zuschlag­ stoffe zur Betriebsmischung können wichtige Ziegeleigenschaf­ ten, wie bspw. Druckfestigkeit, Scherbenrohdichte, Schwindung oder Scherben-Wärmeleitfähigkeit gezielt eingestellt werden. Zur Herstellung von Mauerziegeln wird zunächst der Grundbau­ stoff Ton und/oder Lehm aufbereitet. Hierzu ist nach Gewin­ nung des Tons oder Lehms eine Zwischenlagerung in einem Sumpfhaus vorgesehen, wo verschiedene Tonsorten gemischt werden. Die mechanische Aufbereitung, insbesondere das Zer­ kleinern erfolgt in einem Kollergang. Anschließend werden die Grundstoffe im gewünschten Verhältnis gemischt mit oder ohne Zusatz von Zuschlagstoffen, wie Sand, Ziegelmehl, Asche oder dgl. und befeuchtet. Zur Herstellung wärmegedämmter Mauer­ steine ist eine Porosierung erforderlich durch Zugabe der schon genannten Porosierungsmittel, die ausbrennbare Zusatz­ stoffe, wie Sägemehl, Styropor, Strohhächsel, Papierformstoffe, Torf, Kohlenstaub, etc. sind, die beim Ausbrennen die gewünschten Hohlporen zurücklassen. Aus dem so aufbereiteten Material werden Stein-Rohlingstränge durch Strangpressen geformt und anschließend in einzelne Rohmauersteine abge­ längt, die dann in einen Trockner gelangen und danach in einem Tunnelofen gebrannt werden. Die dabei erfolgende Ver­ brennung der Porosierungsmittel bewirkt die gewünschte Poro­ sität des Mauerziegels.Modern bricks are characterized by a multitude of po technical characteristics with which they deal set it apart from other building materials. The brick factory properties are due to the process technology used, but especially determined by the raw materials used. With the selection of suitable porosity agents and additives Mixing materials can be important brick properties ten such as compressive strength, cullet density, shrinkage or cullet thermal conductivity can be set specifically. For the production of masonry bricks, the basic structure is used first prepared clay and / or clay. This is after winning the clay or loam an intermediate storage in one Swamp house provided where different types of clay are mixed become. The mechanical processing, especially the Zer smaller ones take place in a pan mill. Then the Basic materials mixed in the desired ratio with or without Addition of additives such as sand, brick powder, ash or Like. and moistened. For the production of thermally insulated wall Porosity is required by adding the stones already mentioned porosity agent, the burnable additive materials such as sawdust, polystyrene, straw straw, paper materials,  Peat, coal dust, etc. are the ones that burn out leave the desired hollow pores behind. From the so prepared Stone blanks are made of material by extrusion shaped and then cut into individual raw bricks length, which then get into a dryer and then into be burned in a tunnel kiln. The Ver Burning the porosity causes the desired poro of the brick.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren und eine Mischung der eingangs genannten Art so weiterzubilden, daß eine preiswerte und effektive Porosierung eines Mauerziegels erreicht wird.The object of the present invention is a Process and a mixture of the type mentioned above to further develop that inexpensive and effective porosity a brick is reached.

Diese Aufgabe wird durch das Verfahren gemäß Anspruch 1 gelöst. Eine Mischung zur Lösung der Aufgabe ist im Anspruch 5 angegeben.This object is achieved by the method according to claim 1 solved. A mixture to solve the task is in the claim 5 specified.

Vorteilhafte und zweckmäßige Weiterbildungen der Aufga­ benlösung sind in den Unteransprüchen angegeben.Advantageous and appropriate further training of the task Solution are specified in the subclaims.

Die Erfindung schlägt vor, als Porosierungsmittel Tier­ mehl allein oder in Verbindung mit anderen an sich bekannten Porosierungsmitteln einzusetzen. Tiermehl hat den Vorteil, daß es als organischer Stoff praktisch vollkommen ausbrennt und preiswert einsetzbar ist. Es kann an beliebiger Stelle des Aufbereitungsprozesses vor dem Strangpressen des aufbe­ reiteten Materials zugegeben werden.The invention proposes to use animal porosity flour alone or in combination with others known per se Use porosity agents. Animal meal has the advantage that it burns out practically completely as an organic substance and is inexpensive to use. It can be anywhere of the preparation process prior to extrusion riding material are added.

Die Erfindung schlägt als weitere Ausgestaltung vor, das Tiermehl, das einen hohen Heizwert besitzt, allein oder in Verbindung mit einem oder mehreren an sich bekannten Porosie­ rungsmitteln als Brennstoff für Öfen der keramischen Indu­ strie, insbesondere für Tunnelöfen, zu verwenden, wobei ggf. die Verfeuerung in der Brennzone der Öfen über speziell für den Brennstoff gestaltete Brenner erfolgt.As a further embodiment, the invention proposes that Animal meal, which has a high calorific value, alone or in Connection with one or more porosia known per se agents as fuel for ceramic induction furnaces strie, especially for tunnel kilns, where necessary the firing in the firing zone of the stoves especially for the fuel-designed burner takes place.
