Method and apparatus for packing metal particles with subsequent breaking of packed metal band

An apparatus for the passivating, multistage compaction of hot iron particles supplied in the form of a packed bed from a reduction unit and for the subsequent breaking apart of the compacted iron band is described. Prior to the final compacting, the iron particles pass through a homogenizing and precompressing stage. Thus, the compacted iron has a pore volume of max. 40% and a density of at least 5.5 g/cm3. The iron compacted to a band is subsequently guided between the rollers (7,8,11) of a separating stage exposing it to bending stresses such that it breaks apart at the predetermined desired breaking points. The breaking points have a smaller density than the band regions between them. They can be produced in that in the precompression stage the feed speed is briefly decelerated compared with the feed speed in the compaction stage or in the compaction stage there is less marked compression at these points than in the intermediate regions.
