Rotatable drum drive |
| 摘要 |
A device for treating solid and/or liquid materials comprises a drum driven for rotation about a horizontal axis by means of an endless chain. An expensive toothed rim surrounding the drum is avoided, as it is possible that the chain engages a toothless portion of the drum periphery.
