A treatment apparatus of a waste product for separating recycling fractions, comprising: - a separating column arranged substantially vertically, comprising: a cylindrical body provided on the lateral surface thereof with a plurality of holes and inferiorly of an opening for supply of a waste product to be treated, and a bladed shaft activated in rotation by a first motor and positioned coaxially internally of the cylindrical body; - a first upper discharge mouth arranged in an upper part of the cylindrical body for expelling a first recycling fraction present in the waste product subjected to the treatment, which first recycling fraction is separated and transported upwards by the bladed shaft; - a discharge group for extraction through the first upper discharge mouth and out of the cylindrical body of the first recycling fraction present in the waste product; - the discharge group comprising a discharge conduit connected to the first upper discharge mouth; - a second discharge mouth arranged in the lower part of the cylindrical body for evacuating a second recycling fraction; wherein the bladed shaft inserted in the cylindrical body of the separating column comprises a first rotor on the lateral surface of which a plurality of blades is fixed, orientated so as to define a discontinuous helical winding; and wherein the bladed shaft comprises, in proximity of the upper end, at least a plate fixed to the lateral surface of the first rotor and arranged radially; the treatment apparatus of a waste product being characterised in that it comprises: a screw arranged coaxially internally of the discharge conduit and activated in rotation by a second motor for facilitating extraction of the first recycling fraction present in the waste product from the cylindrical body to the discharge conduit; a dilution group positioned along the separating column for supplying water or like dilution liquids internally of the cylindrical body; and in that the discharge conduit, connected to the first upper discharge mouth, and the screw are arranged parallel to the tangential direction with respect to the cylindrical body, so as to facilitate extraction of the first recycling fraction present in the waste product from the cylindrical body to the discharge conduit; and in that the at least a plate comprises a bent edge at the free end of the at least a plate, which bent edge is inclined so that when the first rotor is activated in rotation in a predetermined rotation activation direction, the bent edge is orientated according to the rotation activation direction so as to facilitate extraction of the first recycling fraction present in the waste product. - a separating column arranged substantially vertically, comprising: a cylindrical body provided on the lateral surface thereof with a plurality of holes and inferiorly of an opening for supply of a waste product to be treated, and a bladed shaft activated in rotation by a first motor and positioned coaxially internally of the cylindrical body;
