Abstract

Procedimento di recupero di materie prime e residui utilizzabili a partire da scorie di acciai speciali per produrre scorie utilizzabili come concime in agricoltura di dimensioni comprese tra 0 e 4 mm, scorie di dimensioni maggiori di 4 mm e particelle metalliche utilizzabili come materia prima. Il procedimento realizza una separazione densimetrica della scoria iniziale mediante una disgregazione selettiva della stessa per mezzo di vagli, mulini e tavole pneumatiche disposte adeguatamente.Procedure for recovering raw materials and residues that can be used starting from slag of special steels to produce slag that can be used as fertilizer in agriculture with dimensions between 0 and 4 mm, slag with dimensions greater than 4 mm and metal particles that can be used as raw material. The process achieves a densimetric separation of the initial slag by means of a selective disintegration of the same by means of suitably arranged screens, mills and pneumatic tables.
