摘要:
Es handelt sich um eine Walzenpresse zum Kompaktieren, Brikettieren und/oder Zerkleinern von Material, insbesondere zum Heißbrikettieren oder Heißkompaktieren. Die Walzenpresse besitzt zwei Presswalzen und eine Zuführvorrichtung, mit der das zu verarbeitende Material dem Walzenspalt zwischen den Walzen zugeführt wird. Die Zuführvorrichtung weist zumindest eine in einem Schneckengehäuse angeordnete und rotierend angetriebene Zuführschnecke auf, welche eine Schneckenwelle und ein daran befestigtes Schneckengewinde aufweist, welches von einer die Schneckenwelle wendelförmig umgebenden Schneckenwendel gebildet wird. Die Walzenpresse ist dadurch gekennzeichnet, dass das Schneckengewinde bzw. die Schneckenwendel in einem dem Walzenspalt zugewandten unteren Endbereich eine größere Steigung aufweist, als in einem dem Walzenspalt abgewandten oberen Bereich.

Method for handling material in a pneumatic pipe transport system, in which material, such as waste material, is input from an input aperture of an input point (3), such as from the input aperture of a refuse chute or of some other input point, and is conducted along a feeder channel (2) with a shaper device (1) arranged in connection with the input point or in the proximity of it, in which case the material to be handled is conducted into the shaper device and/or through it by the aid of at least partly gravity and/or the suction and/or a pressure difference of the pneumatic pipe transport system. In the method the material is handled with one handling means (10) in a shaper device (1), which handling means is rotated around an axis of rotation when handling material and which handling means comprises an aperture (20), which is arranged eccentrically with respect to the axis of rotation of the handling means, that the rotatable handling means (10) arranges the material to be infed into the proximity of the output aperture and, if necessary, shapes the material, together with at least an edge (18) of the output aperture of the rotary shaper and/or the wall of the output channel (4), when the handling means (10) is rotated with a drive device (7).

An apparatus for processing and compressing pulp, comprising a circular perforated sieve base disc and at least one roll wheel circulating and rotating on the sieve base disc, where the sieve base disc and said at least one roll wheel rotating on the sieve base disc are shaped as bevel gears and make up a bevel gear assembly, by which the rotating force can be introduced in the gears of the bevel gear assembly to be partly converted to a compressive force for compressing the pulp to be processed through perforations in the bevel gear like sieve base disc.

A pellet machine includes a hopper feeding a pair of inter-locking counter-rotating dies. Feeders convey material from the hopper to pre-compression rollers on the dies. A mat of the material is rotated on the dies into a nip between the pair of dies. Teeth on each die are in opposed facing relation to the teeth on the opposite die as the teeth rotate into the convergence area in the nip. Pellet forming chambers are inter-leaved between the teeth on both dies. The teeth are offset between the two dies so that the teeth act as plungers driving and compressing the material mat into and through the chambers as the teeth on each die drive into the opposed facing depression between the teeth on the opposite die. The material is driven through the chambers to extrude into the interiors of the dies.
摘要:
Die Erfindung betrifft eine Rollenpresse zur Druckbehandlung oder zur Kompaktierung körnigen Guts aufweisend zwei jeweils über eine Welle in einem Maschinenrahmen drehbar gelagerte und gegenläufig angetriebene, durch einen Walzenspalt voneinander getrennte Loswalzen, wobei die Wellen der Loswalzen in im Maschinenrahmen beweglich angeordneten Lagergehäusen aufgenommen, und wobei jeweils zwei an einer Seite der Walzen angeordnete Lagergehäuse verschiedener Walzen über mindestens einen Anpresszylinder miteinander verbunden sind, der mindestens zwei Arbeitsräume aufweist und ein Verfahren zur Zentrierung von Losrollen in einer Rollenpresse der oben genannten Art. Erfindungsgemäß wird vorgeschlagen, dass die mindestens zwei Arbeitsräume eine entgegengerichtete Kraftwirkung aufweisen und druckmittelschlüssig miteinander verbunden sind, dadurch kann die Hydraulik fest am Maschinenrahmen positioniert werden, wobei dennoch die Walzen schwimmend im Maschinenraum gelagert sind.

Elongate synthetic wood mouldings formed of a settable wood paste comprising wood flour, a binder and a solvent that is flexible under certain conditions and stiff under other conditions are cured, stored, transported and displayed in a coiled form. For use each is warmed in a heated liquid bath, so that it becomes flexible whereafter it is uncoiled and applied to a required surface.
