Device employing vibration for transporting plastic substances with a high coefficient of friction

摘要

In a device for transporting in the plastic state substances with a high coefficient of friction via a pipe (10) in which the substances and the pipe (10) are caused to vibrate relative to one another by one or more vibration generators, the vibrations are transmitted to the above-mentioned pipe (10). Each of the generators (5) can transmit the vibrations to a fluid contained in chambers (7) that are arranged coaxially with and outside of the pipe (10), with the fluid being in contact with the pipe itself.
