<p>The stirrer shaft (RW) is connected to the spreader plate (ST) via a screw joint (AG, IG) extending coaxial to the plate rotation axis. The rotation direction for the joint depends on the plate rotation direction and is chosen so that the rotation resistance encountered by the stirrer shaft as a result of contact with the material intended for spreading acts is directed in the joint tightening direction and in the axial direction of the shaft towards the plate. The spreader comprises at least one spreader plate located beneath a discharge opening (AO) in a vessel containing the material intended for spreading. The plate is rotated about an upright axis in synchronism with a stirrer shaft inside the vessel, the plate and shaft being driven by a common drive device (AW). The stirrer shaft is releasably connected to the spreader plate.</p> |
