Abstract

An improved fragmentation device for a metal material fragmenter comprising an inlet chamber configured to receive metal material and a fragmentation chamber that receives the metal material from the inlet chamber is provided. The fragmentation chamber includes a plurality of hammers linked to a rotor and at least one outlet grate with a plurality of through holes for the outlet of fragmented material from the fragmentation chamber, with the additional fragmentation chamber including a recirculation grate that communicates the fragmentation chamber with the inlet chamber, the recirculation grate being located in a position higher than the rotor inside the fragmentation chamber. The additional grate prevents the device from becoming blocked by an excess load inside the same or by an element that cannot be fragmented.
