Description

Verfahren zum Trocknen in 1Kahlanlagen mit gesonderter Sichtung und Materialumlauf Es ist bekannt, die Trocknung gleichzeitig mit der Mahlung im Mahlraum der Mühle vorzunehmen, was naturgemäß besonders bei Trocknung mit hoher Temperatur für die Lager und andere Einzelheiten der Anlage mit sich bringt.Process for drying in 1Kahlanlagen with separate sifting and Material circulation It is known that drying takes place at the same time as grinding in the grinding chamber of the mill, which naturally occurs especially when drying at a high temperature for the bearings and other details of the facility.

Der Gegenstand der vorliegenden Erfindung ist ein Trocknungsmrfahren in Mühlen mit gesonderter Sichtung und Mahlgutumlauf, das gekennzeichnet ist durch die -Führung der Trockenluft, der Heißluft oder der. Abgase unter Umgehung der Mühle von der Gutaufgabe bis zum Sichter und von da zur Feingutabscheidung. Im besonderen werden hierbei die Gase als Förderluft in der Weise benutzt, daß nur das äußerlich getrocknete Mahlgut zur Mühle und das. von der Mühle kommende, wieder feuchte Bruchflächen aufweisende Mahlgut mit neuer Trokkenluft -zusammengebracht wird und die Mühle so lange durchläuft, bis das Mahlgut die gewünschte Feinheit und damit gleichzeitig die gewünschte Trockenheit erlangt hat.The subject of the present invention is a drying process in mills with separate sifting and regrind circulation, which is identified by the guidance of the dry air, the hot air or the. Exhaust gases bypassing the mill from the feed to the sifter and from there to the separation of fines. In particular the gases are used as conveying air in such a way that only this is externally dried grist to the mill and the. Coming from the mill, again moist fracture surfaces having grist is brought together with new dry air and the mill so runs for a long time until the grist has the desired fineness and thus at the same time has achieved the desired dryness.

In der Zeichnung zeigt Abb. i schematisch eine beispielsweise Anordnung einer Mahl-und Trockenanlage nach dem neuen Verfahren, und zwar bedeutet: h den Ofen für Abgase oder Heißluft, a die Mahlgutaufgabe, f die Förderleitung, w den Windsichter; 1 ,die Staubleitung, e den Exhaustor, c den Staubabscheider, b den Brüdenaustritt, Y das Rück-Laufrohr, m die Mühle und v die Verbindungsleitung zwischen Mühle m und Förderrohr f. In the drawing, Fig. I schematically shows an example of an arrangement of a grinding and drying system according to the new method, namely: h the furnace for exhaust gases or hot air, a the grinding stock feed, f the conveying line, w the air classifier; 1, the dust line, e the exhaustor, c the dust separator, b the vapor outlet, Y the return pipe, m the mill and v the connecting line between mill m and delivery pipe f.

Abb. 2 zeigt :eine anders ausgeführte Anlage zur Durchführung des Verfahrens bei einer Mahl- und Trockenanlage mit geschlossenem Kreislauf, wobei die gleichen Teile durch die gleichen Buchstaben bezeichnet sind. h bedeutet ferner ein Kondensrohr mit Zulauf z und Überlauf u für das Kühlwasser. Der üntiere Teil des Kondensators h ist als Schlammabscheider s ausgebildet.Fig. 2 shows: a differently designed system for carrying out the Method in a grinding and drying plant with a closed circuit, wherein the same parts are denoted by the same letters. h also means a condensation pipe with inlet z and overflow u for the cooling water. The animal part of the condenser h is designed as a sludge separator.

Außer dem obenerwähnten Vorteil; daß die Mühle nicht mit der heißen Luft oder den Gasen in Berührung kommt, hat das neue Verfahren den Vorteil, daß sich jede weitere Apparatur, wie sie bei andern Trockenanlagen benötigt wird, erübrigt.Besides the above mentioned advantage; that the mill is not called with that Comes into contact with air or gases, the new process has the advantage that any further equipment, as required in other drying systems, is superfluous.
