ABSTRACT:
Apparatus for the drying of ferrous or non-ferrous turnings or scrap comprises a vertical axis drier (1) in which a drum (2) which encloses a transporter (3) for the turnings in question is mounted transversely. The turnings are heated indirectly via the drum (2) to evaporate their liquid content, while a protective atmosphere is maintained within the drum to prevent oxidation of the material. The vapors leaving the drum (2) are burnt in the drier (1) to heat the material and render the operation of the apparatus self-sufficient. As an alternative the vapors can be treated to recover their oil content, e.g. by distillation.
