<p>The present disclosure describes a method and an apparatus for the drying of ferrous or non-ferrous turnings, scrap or other materials. The apparatus comprises a vertical axis drier in which a drum which encloses a transporter for the turnings in question is mounted transversely. The turnings are heated indirectly via the drum to evaporate their liquid content, while a protective atmosphere is maintained within the drum to prevent oxidation of the material. The vapours leaving the drum are burnt in the drier to heat the material and render the operation of the apparatus self-sufficient. As an alternative the vapours can be treated to recover their oil content, e.g. by distillation.</p> |
