Definitions
- Figure 5 shows it in side view in the second embodiment.
- the apparatus 1 comprises at least one further conveyor element 9 which has the same structural characteristics described above for said at least one conveyor element 8 and which is positioned around the selection surface 2 so that its widest portion is facing (at least in part) outside the selection surface 2.
- the further conveyor element 9 is mounted around said selection surface 2 so that its most widened end portion faces outside the selection surface 2 in order to convey the material outwards in the internal chamber 4 which did not cross the selection surface 2.
- said further conveyor element 9 is provided/mounted in correspondence of the outlet opening 4" of the internal chamber 4 and is flared towards the outside.
- said further conveyor element 9 is flared towards the direction of advancement/crossing of the material inside the internal chamber 4 from the inlet opening 4' towards the outlet opening 4".
- the term "white slag" refers to a waste resulting from the refining processes of a metal alloy, in particular of steel, during the production chain of the alloy itself, in particular of steel.
- white slag is a waste material very rich in lime and/or other binders and therefore advantageously recoverable.
- black slag we mean the slag that forms, above the steel melting bath, as a result of the oxidation of the scrap and of the compounds generated by the additives inserted in the charge of the electric furnace to produce steel starting from the scrap; suitably, this slag is discharged at the outlet from the electric furnace to be treated in a separate and dedicated way with respect to the liquid steel.
