Light and heavy fractions
Shredding produces light and heavy fractions. Both of these require a coordinated process technology in order to obtain the recyclable materials they contain. An air separator separates the material flow into these two fractions. During the process, the light substances are transported into the expansion chamber by means of air flow. In the chamber, the air velocity is reduced to such an extent that the light substances end up on a discharge belt. Among other items, stones, non-ferrous parts and larger pieces of wood are separated by the heavy fraction. The heavy materials fall downwards onto a discharge belt in front of the rotary drum in the air separator.
