| 摘要 |
The invention relates to a material compacting arrangement for use in a plant intended for the manufacture of rigid, elongated structural elements (4) from binder-moistened loose material (2), comprising a compaction section (7), in which batches of binder-moistened loose material are compacted, a heating section (5) in which the compacted material batches are dried, and a transport arrangement which is intended to cause each of the material batches compacted in the compaction section to pass through the heating section (5). The compaction section (7) is constructed to impart to the front material batch (2a), as seen in the feed direction, over a short transport path, a higher degree of compaction than a following, pre-compressed material batch (2b) over a longer transport path, by using a screw compressor (10) for pre-compressing the material batch and a press roll for finally compressing, or compacting, (20) the batch. |
