Abstract

In this roller mill (3) with a vertical axis (1), the grinding rollers (5) are mounted via the grinding roller shafts (6) in bearing housings (7) which are equipped with rolling bearings and which are fastened outside the roller mill housing on concrete foundations (9). Between the bearing housings (7) of the grinding roller bearing arrangement and the concrete foundations (9) are situated so-called scissor lift tables (8) which, by means of an integrated hydropneumatic suspension, press the grinding rollers inside the roller mill housing onto the material for grinding situated on the grinding plate (3) and carry out the grinding process. Moreover, the scissor lift tables (8) have the function of stabilizing the grinding rollers (3) against tangential forces and of allowing only a pure vertical movement for the grinding rollers. This means that a tilting of the grinding rollers is effectively prevented by the scissor lift tables. The scissor lift tables with the grinding roller units fastened thereon stand on fixable movable bases, with the result that the grinding roller units can be moved individually out of the roller mill housing or the grinding rollers can be slightly displaced radially on the grinding plate.

Description

Rollenmühle Beschreibung:  Roller Mill Description:
[0001] Die Erfindung betrifft eine Rollenmühle entsprechend dem Oberbegriff des Anspruch 1. The invention relates to a roller mill according to the preamble of claim 1.
[0002] Eine Rollenmühlen bekannter Art ist in dem Patent DE 38 01 728 C2 beschrieben. Hier wird eine Schiefstellung der Mahlrolle bei dem Ausweichen während der Mahlung nicht verhindert, was dazu führt, das die Mahlrolle auf dem Mahlteller ihre Abrollposition ändert, die Mahlrolle nur auf der Mahlrollenkante abrollt, die Effektivität der Mahlung nachlässt und Verschleiß vornehmlich auf der Kante der Mahlrolle auftritt. Hauptsächlich das Verschleißbild kann bei heutigen bekannten Rollenmühlen deutlich beobachtet werden. A roller mills known type is described in the patent DE 38 01 728 C2. Here, a misalignment of the grinding roller in the evasion during grinding is not prevented, which causes the grinding roller on the grinding table changes its rolling position, the grinding roller rolls only on the Mahlrollenkante, the effectiveness of the grinding decreases and wear primarily on the edge of the grinding roller occurs. Mainly the wear pattern can be clearly observed in today's known roller mills.
[0003] Eine wesentlich bessere Rollenmühlenvariante ist in der DE 103 38 154 A1 beschrieben. Hier wird durch die Lenkergeführte Rollenlagerung außerhalb des Rollenmühlengehäuses zwar jede Schiefstellung der Mahlrolle vermieden, jedoch ist durch die Auslenkung der Mahlrolle eine unkontrollierte Positionsverschiebung der Mahlrolle auf dem Mahlteller zwangsläufig nicht vermeidbar, mit der Folge einer ebenfalls uneffektiveren Mahlung. A much better roller mill variant is described in DE 103 38 154 A1. Here, although any misalignment of the grinding roller is avoided by the handlebar-guided roller bearing outside of the roller mill housing, however, an uncontrolled positional shift of the grinding roller on the grinding table is inevitably inevitable by the deflection of the grinding roller, with the result of a likewise less effective grinding.
[0004] Der Erfindung liegt daher die Aufgabenstellung zugrunde, eine Rollenmühle entsprechend dem Oberbegriff des Anspruches 1 so auszubilden, das eine The invention is therefore the task of designing a roller mill according to the preamble of claim 1, the one

[0005] Die erfindungsgemäße Rollenmühle besteht aus einem Rollenmühlegehäuse mit vertikaler Achse. In dem Rollenmühlengehäuse ist der Mahlteller mit seiner Unterseite auf einem vertikalen Lagerring drehbar gelagert. Auf der Oberseite des Mahltellers überrollen die dort befindlichen Mahlroilen das auf dem Mahlteller liegende Mahlgut um es zu zerkleinern. Es können zwei oder mehrere Mahlrollen angeordnet sein. Der Mahlteller wird durch einen unterhalb des Mahltellers im The roller mill according to the invention consists of a roller mill housing with a vertical axis. In the roller mill housing, the grinding table is rotatably mounted with its underside on a vertical bearing ring. On the upper side of the grinding plate, the grinding grinders located there roll over the grinding material lying on the grinding plate in order to comminute it. It can be arranged two or more grinding rollers. The grinding plate is inserted through a below the grinding plate in the
Rollenmühlengehäuse angeordneten Getriebe mit vertikalem Abtrieb und außerhalb des Rollenmühlengehäuses aufgestelltem Antriebsmotor in Rotation versetzt. Weiter ist es möglich, auch über angetriebene Mahlrollen, deren Antriebs-Motor- Getriebeeinheit sich außerhalb des Rollenmühlengehäuses befinden, den Mahlteller in Rotation zu versetzen. Es sind damit unterschiedliche Antriebsvariänten für den Mahlteller möglich. Auch Kombinationen der beschriebenen Antriebe sind möglich. Roll mill housing arranged gear with vertical output and placed outside the roller mill housing drive motor set in rotation. It is also possible, also via driven grinding rollers whose drive motor gear unit are outside the roller mill housing, the grinding table to set in rotation. There are thus different drive variants for the grinding table possible. Combinations of the described drives are possible.
[0006] Die Mahlrollen werden über die Mahlrollenwellen in mit Wälzlagern oder Gleitlagern bestückten Lagergehäusen gelagert. Während die Mahlrollen innerhalb des Rollenmühlengehäuses auf dem Mahlteller abrollen, befindet sich die mit Wälzlagern oder Gleitlagern bestückten Lagergehäuse zur Lagerung der Mahlrollen über die Mahlrollenwellen außerhalb des Rollenmühlengehäuses, befestigt auf Scherenhubtischen, die auf außerhalb des Rollenmühlengehäuses angeordneten Betonfundamenten verankert sind. Mit in den Scherenhubtischen angeordneten hydropneumatischen Federn werden die Mahlrollen über die Mahlrollenwellen innerhalb des Rollenmühlengehäuses auf das auf dem Mahlteller liegende Mahlgut gepresst. The grinding rollers are mounted on the Mahlrollenwellen in stocked with roller bearings or plain bearings bearing housings. While the grinding rollers roll inside the roller mill housing on the grinding table, the bearing housing equipped with roller bearings for supporting the grinding rollers on the Mahlrollenwellen outside the roller mill housing, mounted on Scherenhubtischen which are anchored to outside the roller mill housing arranged concrete foundations. With arranged in the scissor lift hydropneumatic springs, the grinding rollers are pressed on the grinding roller shafts within the roller mill housing on the lying on the grinding table regrind.
[0007] Die Aufgaben der Scherenhubtische sind die Mahlrollenlagerung zu tragen, die Mahlrollen auf dem Mahlteller tangential und radial zu fixieren, ein Kippen der Mahlrollen zu verhindern, Mahlkräfte von den Mahlrollen auf die Fundamente zu übertragen und die Ausbaufähigkeit der Mahlrolleneinheiten zu erleichtern. Über einstellbare Anschläge innerhalb der Scherenhubtische sind die Mahlrollen innerhalb des Rollenmühlengehäuses oberhalb des Mahltellers so einstellbar, das bei nicht genügender Belegung des Mahltellers mit Mahlgut ein Nullspalt zwischen den Mahlrollen und dem Mahlteller einstellbar ist. Dies verhindert, das die Mahlrollen auf den Mahlteller aufliegen können und diesen dann beschädigen. Über die The tasks of the scissor lift tables are to carry the Mahlrollenlagerung to fix the grinding rollers on the grinding table tangentially and radially, to prevent tilting of the grinding rollers to transfer grinding forces from the grinding rollers on the foundations and to facilitate the expandability of Mahlrolleneinheiten. About adjustable stops within the Scherenhubtische the grinding rollers within the roller mill housing above the grinding plate are adjustable so that when not enough occupancy of the grinding table with regrind a zero gap between the grinding rollers and the grinding table is adjustable. This prevents the grinding rollers from resting on the grinding table and then damaging it. About the
