Description

Verfahren zur 1Vlahlung von Faserstoffen für die Papierfabrikation in Kegelstoffmühlen. Ulm den Durchgang des Faserstoffes durch die Kegelstoffmühle bei der bisher gebräuchlichen Arbeitsweise zu ermöglichen, ist eine bestimmte Verdünnung der Stoffmasse mit Wasser unerläßlich. Steigert man die Stoffdichte, so verringert sich die Durchflußgeschwindigkeit der durch die Mühle geförderten Stoffmasse, um schließlich ganz aufzuhören. Bei der bisher gebräuchlichen Arbeitsweise der Kegelstoffmühlen, die mit einer großen Wasserverdünnung des Stoffes arbeiten müssen, wird der Kraftbedarf bedingt durch die Mahlung des Stoffes, durch die Förderung von Wasser und Stoff und durch die Flüssigkeitstreibung. Hierbei ist der durch das Wasser bedingte Kraftverbrauch nicht unerheblich.Process for the lamination of fiber materials for paper manufacture in cone pulp mills. Ulm the passage of the pulp through the cone pulp mill A certain dilution is required to enable the previously common method of working the mass of matter with water is indispensable. If you increase the consistency, you decrease it the flow rate of the mass of matter conveyed through the mill finally stop completely. In the previously common way of working with cone pulp mills, who have to work with a large water dilution of the substance becomes the power requirement due to the grinding of the material, through the pumping of water and material and by the fluid drift. Here is the power consumption caused by the water not insignificant.

Die Erfindung bezweckt, den Faserstoff der Mühle mit geringerer Wasserverdünnung zuzuführen, um hierdurch bei. gleichzeitiger Verringerung des Kraftverbrauches die Mahlwirkung erhöhen oder bei gleichem Kraftaufwand eine größere Stoffmenge verarbeiten zu können. Zu diesem Zwecke wird dem die Mühle passierenden Stoff bei oder vor seinem Eintritt in die Mühle eine gewisse Menge Gas (Luft) zugeführt und auf diese Weise der Stoff mit Luft durchsetzt. Diese Durchsetzung des Stoffes mit Luft gestattet einen dickeren Eintrag (größere Konsistenz) des Stoffes und befördert die Mahlung. Es ist selbstverständlich auch- möglich, die Luftzuführung nicht nur beim Eintritt in die Mühle, sondern auch während des Stoffdurchganges durch die Mühle zu bewirken.The invention aims to make the pulp of the mill with less water dilution in order to thereby help. simultaneous reduction of the power consumption Increase the grinding effect or process a larger amount of material with the same amount of force to be able to. For this purpose, the material passing through the mill is at or in front of his Entering the mill a certain amount of gas (air) is supplied and in this way the fabric is permeated with air. This permeation of the substance with air is permitted a thicker entry (greater consistency) of the substance and promotes grinding. It is of course also possible to have the air supply not only at the entrance in the mill, but also during the passage of material through the mill.
