1. A method for producing granulated metallic units (GMUs), the method comprising:
reducing a sulfur content of molten metallics to produce desulfurized molten metallics;
feeding the desulfurized molten metallics to one of first or second granulator units, wherein feeding comprises:
transferring the desulfurized molten metallics into a tundish of one of the first or second granulator units,
directing the desulfurized molten metallics from the tundish into a reactor of one of the first or second granulator units, and
granulating the desulfurized molten metallics in the reactor to form GMUs;
filtering the GMUs in a dewatering assembly to form a filtrate and transferring filtrate from the dewatering assembly to a classifier assembly of one of the first or second granulator units, and
classifying, at the classifier assembly, the filtrate to output GMU fines having an average size of less than 1 mm.
