Drying drum for fluid materials

摘要

The present drying drum includes a roller supported drum jacket which is connected at one end thereof to a drive shaft by means of radially extending arms whereby the drive shaft extends coaxially with the rotational axis of the drum jacket. The drive means proper are guided relative to said drive shaft by guide means forming part of the drive shaft itself or either by a bearing surface forming part of a spur gear connected to the drive shaft. The drive means are further connected through a guide rod with an abutment means for taking up the drive reaction.
