Bei diesen Verfahren und den su ihrer Ausübung notwendigen Einrichtungen wird Jedoch vielfach der die Mlsohgutqualltflt bestlmeende EinfIu3 des FUllgrades lsi Nisoher nloht berücksichtigt. So ist z.B. einleuchtend, dal bei mangelnder füllung des Mischers eine genügende Durohmleohung durch die Mischorgane nicht möglich ist· Ebenso leidet erfahrungsgemäß der Mischeffekt auch hei tlberfttllung des Mischers. Diese Erkenntnisse haben sowohl fttr das Knetmisohen als auch fur die sogenannten Auflockerungs- bzw. Schwebeschlcht-Miechverfahren Oültlgkeit.In these procedures and those necessary for their practice Facilities, however, are often subject to the quarrying of waste The determining influence of the fill level is not taken into account. For example, it is evident that if the mixer is insufficiently filled, there will be sufficient resistance through the mixing elements is not possible · Experience has shown that the mixing effect also suffers also hot filling of the mixer. These findings are valid both for kneading and for the so-called loosening or floating-smelting process.
