摘要

Pneumatic conveying machine comprises a compressor (5), a pipeline (4) consisting of at least one rigid pipe section (4a) and at least one flexible tube section (4b), and a drive (6) for rotating the rigid pipe section about its longitudinal axis. The flexible tube section is fixed at one end to the rigid pipe section so that it does not rotate and its other end is positioned in a suitable pivot bearing (7). Preferred Features: The rigid pipe section is arranged in the middle section of the pipeline between at least two flexible tube sections.
