Abstract

Plants and methods recover spent refractory material and comprise at least one receiving area for said refractory material, at least one material sieving area, at least one magnetic separation area, and at least one sorting area. Said receiving area communicates with a first sieving area divides said refractory material in at least two fractions based on sizes of said refractory material. A second sieving area divides a fine fraction into at least two sub-fractions.

Abstract

Plant for the recovery of spent refractory material in steel plants, comprising at least one receiving area (1) for said refractory material, at least one material sieving area (2), at least one magnetic separation area (3) and at least one sorting area (4). Said receiving area (1) communicates with a first sieving area (2) comprising first sieving means intended to divide said refractory material in at least two fractions, of which a coarse fraction and a fine fraction, on the basis of the size of said material. There is further provided a second sieving area (21) comprising second sieving means intended to divide said fine fraction into at least two further subfractions (A, B, C) on the basis of size.
