  • Patent number: 7398729
    Abstract: A compacting press for powdery to granular bulk materials, comprising two counterrotating rollers (1,2), arranged in one plane, which rollers (1,2) are held in a roller housing (11). At least one of the two rollers (1,2), preferably the top roller (1), is a loose roller which is flexibly supported by force generators (16,17). Each roller (1,2) at each of its two sides (1a, 1b, 2a, 2b) comprises its own electric motor drives (18a, 18b, 19a, 19b, 21a, 21b, 22a, 22b). The loose roller (1) bears these drives (21a, 21b, 22a, 22b). For easy installation and deinstallation, the roller housing (11) with a vertical design comprises two separate parts (11a, 11b), namely a bottom part (11b) comprising one roller (2) and a top part (11a) with the loose roller (1), wherein said top part (11a) is held by a swivel bearing (13) to the bottom part (11b) and is lockable. In this arrangement, the top part (11a) can be swiveled open by way of the swivel bearing (13).

  • Patent number: 7014448
    Abstract: A compacting facility for bulk goods is disclosed. In order to generate flakes of homogeneous quality, the bulk good is conveyed to a roller press (4) via a screw conveyor (5). The roller press (4) is supplied with bulk goods of differing quality from two shafts (7,9) positioned one behind the other, the screw conveyor (5) being underfed from the first shaft (9) in the direction of conveyance with granulate, which is not suitable for further processing, arising after the roller press (4) and the rest of the feeding being from the last shaft (7) in the direction of conveyance.
