(57) The invention is related to the technical field of granulated product sorting apparatus,
and in particular to the mill grinding field. The technical problem to be solved was
that of practically eliminating high inertia moving parts from such apparatus. The
solution to the problem is provided by one such apparatus comprising members (14)
generating a forced air circulation between the feeding means (5) and discharging
means (6) for the product to be sorted so as to create, at each screening layer (4),
a forced air flow mixed up with the product to be sorted and capable of determining
its sorting in a substantially spontaneous fashion.
