    Verfahren zum Nutzbarmachen der beim Brechen von Kalkstein sich ergebenden Kalksteinabf lle.   
 EMI1.1 
 der sonstigen technischen Aufarbeitung des alksteins, z. B. für die Eisenbahnschottererzeugung und selbst beim gewöhnlichen   Kalksteinbruchbetriebe, ergibt   sich durch das Sprengen und Brechen ein grosser Prozentsatz unbenutzbarer Kalksteinabfälle, welche, da sie ununterbrochen aus den   Kaiksteinbruchen   entfernt werden müssen, eine erhebliche Verteuerung der Kalksteinproduktion zur Folge haben. Ausserdem   beträgt   dieser KalksteinBruchabfalt oft bis zu   4U    des gesprengten und gewonnenen Rohmaterials, weiches bisher nicht nur vollkommen wertlos war, sondern für den ganzen Betrieb einen kostspieligen Ballest bildete.

   Es entstehen an den   Kalksteinbrüchen   Kalsteinhalden von unvetrwendbarem   Steingeröil.   welches zum Nachteil des Bergbaues zu den Kosten der Kalkerzeugung durch

   Gegenstand der vorliegenden Erfindung hilft diesem Übelstande ab und betrifft ein Verfahren zur Verwertung dieser Kalksteinabfälle. Dies geschieht dadurch, dass man die auf entsprechende Korngrösse gebrachten Kalksteinstücke (etwa 10 bis 15 mm im Durchmesser) be ihrem Austritt aus dem Ofen   durch einen Hxhaustor   von der Flugasche und

Zweckmässig wird man, wenn man Haldenabfälle zu Briketts verarbeitet, dieselben in einem geeigneten Ofen. z. B. Drehrohr- oder Schättelofen, brennen und unter Ausputzung der durch den Brennprozess dem Ätzkalk erteilten Wärme die Pressung bewirken.

   Soll die Verarbeitung von Stückenätzkalk zu Briketts statifinden, so kann das Brennen In einem beliebigen Kalkofen, z. B. Schacht-, Ringofen usw., stattfinden.

    Process for utilizing the limestone waste resulting from the crushing of limestone.
 EMI1.1
 the other technical processing of the alkestone, z. B. for railway ballast production and even in ordinary limestone quarries, the blasting and crushing result in a large percentage of unusable limestone waste, which, since it has to be continuously removed from the quarry quarries, makes limestone production considerably more expensive. In addition, this limestone debris is often up to 4U of the blasted and extracted raw material, which up to now was not only completely worthless, but also formed an expensive ballest for the entire company.

   Limestone heaps of irreversible stone oil arise in the limestone quarries. which to the detriment of mining to the cost of lime production through
 EMI1.2
 to technically utilize this limestone waste.



   The present invention remedies this drawback and relates to a method for utilizing this limestone waste. This is done by removing the pieces of limestone (about 10 to 15 mm in diameter), which have been brought to the appropriate grain size, from the fly ash and through an Hxhaustor as they exit the furnace
 EMI1.3
 Processing the quick lime to briquettes the method is to be carried out in this way. that the quick lime is pressed into briquettes in its hot condition at around a temperature of 100 to 1: where C. It is expedient when processing dump waste into briquettes, the same in a suitable oven. z. B. Rotary kiln or Schättelofen, burn and cause the pressing while using the heat given to the quick lime by the burning process.

   If the processing of pieces of lime to briquettes is to take place, the burning can be done in any lime kiln, e.g. B. shaft furnace, ring furnace, etc., take place.
