Abstract: A process and apparatus for separating briquettes and fragments in a product stream resulting from briquetting direct reduced iron. Separating and cooling of the briquettes and fragments are carried out simultaneously in an initial step with use of separating means submerged in a cooling bath. The process enables use of less rugged apparatus following the initial step and the apparatus is not subjected to handling the product stream at the elevated temperatures at which briquetting is carried out. Capital expenditure and equipment maintenance is thus reduced.
