The invention relates to a screening, crushing or mixing bucket, which is formed into a bucket of an excavating machine or bucket loader. The bucket comprises a bottom plate (1), side walls (2), and at the back of the bucket working drums (3) rotatable about their shafts, which screen, crush or mix the material in the bucket as they rotate and at the same time deliver screened, crushed or mixed material out of the bucket, between or through the working drums (3). In the bucket are casings (4) for the power transmission and bearings of the working drums (3). The casings (4) are limited by frame plates (5) to which the bearing housings (6) of the drums (3) are attachable. On the frame plate (5) and/or on the inner side of the inner wall (2) is fixed a mudguard (10), which extends between the shafts of the working drums (3), next to the lead-throughs of the shafts, and the mudguard (10) comprises cut-outs (11) for receiving the shafts of the working drums (3).

Bei einem Knetkörper für Extruderschneckenmaschinen sind in den radial außenliegenden Bereichen höchster Beanspruchung verschleißfeste Materialien angebracht. Um die verschleißfesten Materialien ohne Gefahr des Ausbrechens oder Abplatzens und ohne negative Beeinflussung des Verschleißwiderstandes des Knetkörpers selber in einfacher Weise an diesem anbringen zu können, ist in jedem Bereich höchster Beanspruchung (Knetkanten 17, 18) mindestens ein weitgehend vom Knetkörper (1) umgebenes und dauerhaft an diesem befestigtes Einsatzteil aus verschleißfestem Material vorgesehen.

An apparatus is equipped with first and second rotary shaft 3, 4 and a plurality of disks 40, 50 provided upright at equal intervals on the respective rotary shaft. The disks are heated or cooled from the inside, and a raw material is heated or cooled by bringing it into contact with the disk surfaces. Scraper members 45, 45' and 55, 55' that enter between the surfaces of the facing adjacent disks to scrape the raw material are fixed to each of the disks 40, 50. The first and second rotary shafts 3, 4 are rotated at unequal speeds such that the scraper members approach the facing disk surfaces with trajectories drawn thereon varying, so that the raw material that has adhered to the disk surfaces can be effectively scraped off.

Es wird eine Vorrichtung zur Behandlung von viskosen Substanzen beschrieben bestehend aus einem beheizbaren Behälter mit Mischguteinlaß auf der einen und Mischgutauslaß auf der anderen Seite und mehreren gleichsinnig rotierenden Wellen, auf denen Mischelemente angebracht sind, dadurch gekennzeichnet, dass die Mischelemente aus zwei Lagen gekreuzt zueinander angeordneter Stege bestehen, die miteinander verbunden sind. An den Stirnseiten der Stege sind axial ausgedehnte Stifte angebracht. Diese reinigen die Zwischenräume zwischen den Stegen der Mischelemente der benachbarten Welle.
