Eine weitere vorteilhafte Ausgestaltung der Prallmühle besteht darin, daß die Rückwand der Tasche um ihre Unterkante verschwenkbar und dadurch der Winkel zwischen dem Taschenboden und der Rückwand veränderbar ist. Man kann auf diese Weise die Stufung der dem Verschleiß ausgesetzten Enden der Schbg- und Pralleisten verändern oder wiederherstellen. Da die Tasche selbst verschwenkbar gelagert ist, kann man die mit dem Verschwenken der Rückwand entstehende Veränderung des Mahlspaltcs durch entsprechendes Verschwenken der Tasche in entgegengesetztem Sinne wieder rückgängig machen, was bei der Ausbildung nach dem Hauptpatent, bei der die Rückwand auch verschwenkbar angeordnet ist, nicht möglich istAnother advantageous embodiment of the impact mill consists in the fact that the rear wall of the bag can be pivoted about its lower edge and thereby the angle can be changed between the bottom of the bag and the rear wall. One can do the grading this way the exposed ends of the Schbg and Change or restore baffles. Since the bag itself is pivoted, you can use the with the pivoting of the rear wall resulting change of the Mahlspaltcs by corresponding Pivoting the bag in the opposite direction undo what was done during training according to the main patent, in which the rear wall can also be pivoted is arranged, is not possible
Ist zur erzielung einer guten Abdichtung des Gestells gegenüber dem Gehäuse oben an dem Gestell eine in Verfahrrichtung verlaufende, waagerechte, die Tasche überragende Platte vorgesehen, die in eingefahrenem Zustand des Gestells zusammen mit den darüber angeordneten festen Teilen des Mühlengehäuses die Abdichtung bewirkt, so ist nach einer weiteren Ausgestaltung gemäß der Erfindung die Platte oder ein dem Innern des Mühlengehäuses zugewendeter Teil von ihr hochklappbar ausgebildet, damit die Platte einerseits zur Erzielung einer guten Abdichtung genügend lang ist und andererseits das Abheben der Tasche von dem Gestell nicht behindert.Is to achieve a good seal of the frame against the housing at the top of the frame an in Direction of travel running, horizontal plate protruding beyond the pocket provided, which in retracted Condition of the frame together with the fixed parts of the mill housing arranged above the seal causes, according to a further embodiment according to the invention, the plate or one of the interior of the Mill housing facing part of it designed to be folded up so that the plate on the one hand to achieve a good seal is long enough and on the other hand not lifting the bag from the frame with special needs.
Zum Schutz der Abdichteinrichtungen, die meist aus sich gegen die Platte anlegenden Gummilippen bestehen, ist im Innern des Mühlengehäuses vor dem Spalt zwischen der Piatte und dem ihr zugewendeten Teil des Mühlengehäuses ein Prallbalken angeordnet.To protect the sealing devices, which usually consist of rubber lips resting against the plate, is inside the mill housing in front of the gap between the plate and the part of the facing it Mill housing arranged a baffle bar.
In der Zeichnung ist eine Prallmühle gemäß der Erfindung im Querschnitt dargestellt.In the drawing is an impact mill according to the invention shown in cross section.
In dem Gehäuse 1 der Prallmühle ist ein Rotor 2 gelagert, der um die Achse 3 umläuft und an seinem Umfang Schlagleisten 4 aufweist Oberhalb des Rotors sind zwei Prallwerke 5 und 6 vorgesehen, die mit Pralleisten 7 gepanzert sind. Seitlich des Rotors befindet sich eine Mahlbahn 8, die durch die Stirnflächen von gebrauchten Schlag- und/oder Pralleisten 4, 7 gebildet ist. die in einer Tasche 9 gestapelt sind. Die Tasche ist durch einen Boden 10, eine Rückwand 11 und Seitenwände 12 gebildet und auf einem Gestell 13 gelagert, das mittels Rollen 14 auf Schienen 15 verfahrbar ist. Die Tasche 9 ist an ihrem unteren Ende mit gabelartigen Teilen 16 versehen, mit denen sie sici» auf eine Querstange 17 des Gestells 13 auflegt, während sie sich mit ihrem oberen Ende gegen einen Anlagetcil 18 abstützt. Dieses AnIageteil ist als Bolzen ausgebildet, der an einem Schieber 19 vorgesehen ist. Der Schieber liegt auf einer Gleitbahn 20 des Gestells 13 und kann mittels einer hydraulischen Zylinder-Kolbcn-Einheit 21 verschoben werden. Er ist außerdem durch eine Klemmvorrichtung 22 auf der Gleitbahn feststellbar. Die Tasche 9 ist mit einem hakenartigen Ansatz 23 versehen, der den Bolzen 18 übergreift.In the housing 1 of the impact mill, a rotor 2 is mounted, which rotates around the axis 3 and on his Circumference has impact strips 4 Above the rotor, two impact mechanisms 5 and 6 are provided, which are provided with impact strips 7 are armored. To the side of the rotor is a grinding track 8, which is used by the end faces of Impact and / or impact strips 4, 7 is formed. which are stacked in a pocket 9. The bag is through a bottom 10, a rear wall 11 and side walls 12 formed and mounted on a frame 13, which by means of Rollers 14 can be moved on rails 15. The pocket 9 is provided with fork-like parts 16 at its lower end provided with which they sici »on a crossbar 17 of the Frame 13 is placed while its upper end is supported against a plant part 18. This part of the plant is designed as a bolt which is provided on a slide 19. The slide lies on a slide 20 of the frame 13 and can be moved by means of a hydraulic cylinder-piston unit 21. It can also be locked on the slide by means of a clamping device 22. The pocket 9 is with a hook-like projection 23 is provided which engages over the bolt 18.
Die gabelartigen Teile 18 sind im Verhältnis zum Gesamtschwerpunkt der gefüllten Tasche so angeordnet, daß die Tasche nach außen zu kippen sucht und sich daher fest gegen den Bolzen 18 anlegt. Die Rückwand 15 der Tasche kann um ihre Unterkante 24 verschwenkbar ausgebildet sein. Zum Angreifen des Hebezeuges ist im oberen Teil der Tasche $ ein Bolzen 25 vorgesehen.The fork-like parts 18 are in relation to the overall center of gravity the filled bag arranged so that the bag seeks to tilt outwards and itself therefore rests firmly against the bolt 18. The rear wall 15 of the pocket can pivot about its lower edge 24 be trained. A bolt 25 is provided in the upper part of the pocket $ to grip the hoist.
Zwecks Abdichtung des oberen Endes des Gestells 13 gegenüber dem Mühlengehäuse 1 sind beide Teile mit in Ein- und Ausfahrriehtung verlaufenden Platten 26 bzw. 27 versehen, zwischen denen Abdichtungslippen 28 vorgesehen sind. Zum Schutz dieser Abdichtungsmittel vor den vom Rotor abgeschleuderten Gutteilen ist das zweite Prallwerk 6 vor dem Abdichtungsspalt angeordnet Damit die Platte 26 das Abheben der Tasche von dem Gestell nicht behindert, ist sie um eine Achse 29 hochklappbar ausgebildet. Eine Klemmvorrichtung 30 dient dem Feststellen des Gestells 13 auf den Schienen 15.In order to seal the upper end of the frame 13 against the mill housing 1, both parts are in Inward and outward extending plates 26 resp. 27 is provided, between which sealing lips 28 are provided. To protect this sealant before the good parts thrown off by the rotor, the second impact device 6 is arranged in front of the sealing gap So that the plate 26 does not hinder the lifting of the bag from the frame, it is designed so that it can be folded up about an axis 29. A clamping device 30 is used the fixing of the frame 13 on the rails 15.
