Description

Verfahren zum Zerschneiden von Steinen Gegenstand der Erfindung ist ein, insbesondere für harte Gesteine, mit gutem Erfolge anwendbares Verfahren zum Zerschneiden von Steinen, nach dem es ohne weiteres möglich ist, beispielsweise aus Basalt, Grauwacke, Granit, Gneis u. dgl., leicht und schnell Pflastersteine mit glatten Außenflächen herzustellen, die ein sehr wertvolles, haltbares Pflastermaterial bilden.Method for cutting stones is the subject of the invention a method that can be used with good results, especially for hard rocks, for Cutting up stones after which it is easily possible, for example Made of basalt, greywacke, granite, gneiss and the like, easy and quick paving stones with smooth outer surfaces, which is a very valuable, durable paving material form.

Das neue Verfahren besteht darin, daß man das zu zerschneidende Gestein einer runden Flußeisenscheibe entgegenführt, die mit hoher Umlaufgeschwindigkeit, beispielsweise 9o bis I2o msec., angetrieben wird; wie es zum Schneiden von Metallen bekannt ist. Die Wirkung dieser rasch umlaufenden Scheibe ist wahrscheinlich so zu erklären, daß zwischen dem äußeren Umfange der Scheibe und dem Gestein eine große Reibung und dadurch eine solche Erhitzung des Steines entsteht, daß entweder Bestandteile des Steines geschmolzen und weggeschleudert oder an der Luft verbrannt werden. Versuche haben bestätigt, daß die Schneidgeschwindigkeit der umlaufenden Flußeisenscheibe bei den harten Eruptivgesteinen eine so große ist, daß das Verfahren durchaus wirtschaftlich ist. Es sind Kreissägen mit glatten Rändern bekannt, die unter Zuhilfenahme von Sand als Schleifmittel als Steinbearbeitungsmaschinen dienen. Von dieser vorbekannten Einrichtung unterscheidet sich die Erfindung dadurch, daß bei dieser ein Schleifmittel nicht verwendet wird.The new method is that you can cut the rock towards a round disc of fluent iron, which at high speed, for example 9o to I2o msec., is driven; like it for cutting metals is known. The effect of this rapidly rotating disk is probably like that to explain that between the outer circumference of the disc and the rock there is a large Friction and thereby such a heating of the stone arises that either constituents of the stone melted and thrown away or burned in the air. try have confirmed that the cutting speed of the rotating fluid iron disk in the case of hard igneous rocks it is so large that the process is entirely economical is. Circular saws with smooth edges are known which, with the aid of Sand as an abrasive serve as stone processing machines. From this previously known The device differs from the invention in that it uses an abrasive is not used.

PATENTANSPRUCH: Verfahren zum Zerschneiden von Steinen, insbesondere zu Pflastersteinen, mittels umlaufender, schleifend wirkender Scheiben, denen der zu zerschneidende Stein zugeführt wird, dadurch gekennzeichnet, daß als Schleifscheibe eine dünne Flußeisenscheihedient, die mit hoher Umlaufsgeschwindigkeiit angetrieben wird und ohne Zuhilfenahme eines Schleifmittels (wie Sand o. dgl.) arbeitet. PATENT CLAIM: A method for cutting stones, especially paving stones, by means of revolving, grinding disks to which the stone to be cut is fed, characterized in that a thin fluvial iron sheet is used as the grinding wheel, which is driven at a high rotational speed and without the aid of an abrasive (such as Sand or the like) works.
