1. An apparatus for separation of at least two synthetic materials in particulate form having different characteristics, the apparatus comprising:
a rotating drum (2) having a cylindrical shape with a tapered truncoconical end (21) and an opposite flat bottom wall (221);
a device (234) configured to set the drum in rotation;
a conduit (24) configured to introduce into the drum (2) a mixture composed of at least two synthetic materials in particle form, having different specific weights, and of a liquid, having an intermediate specific weight relative to the specific weights of the two products;
a radial discharge hole (5) located in the lateral wall of the tapered end of the drum;
an axial slithering discharge opening (6) located in the flat bottom surface (221) of the drum, at a distance d from the axis of the drum (2);
a rotor (3) located inside the drum (2) provided with a first external helical blade (32) having the same external shape as the drum (2) shape and having respective cylindrical (322) and tapered conical (321) portions;
a device (313) configured to set the rotor (3) in rotation relative to the drum (2), in such a way that the rotor pushes the material towards the tapered end of the drum; wherein the first external helical blade (32) extends along the entire length of the drum (2) and is located at a distance from the axis of the rotor and of the drum greater than the distance between the drum axis and the axial discharge opening provided in the non-tapered section drum bottom, wherein the rotor (3) comprises a second helical blade (320), inside the first helical blade (32) and wrapped at a distance from the drum axis in an opposite direction than that of the first helical blade (32), the second helical blade (320) extending for the entire length of a cylindrical tract (22) of the drum (2), and being supported to the first helical blade (32) at cross points with the first helical blade (32) to leave free the axial portion of the drum.
2. The apparatus according to claim 1 wherein the rotor (3) rotates in the same direction of rotation as the drum (2).
3. The apparatus according to claim 1 wherein the axial discharge opening (6) located on the non-tapered section bottom wall (221) of the drum (2) is at a distance from the axis of the drum which distance is greater than a minimum radius of the tapered section of the drum (2).
4. The apparatus according to claim 1 wherein a ring (323) is located between the cylindrical portion (322) and the conical portion (321) of the first helical blade (32) to separate said portions.
5. The apparatus according to claim 4 wherein the second helical blade (320) ends against the ring (323) separating the cylindrical portion (322) and the conical portion (321) of the first helical blade (32).
6. (canceled)
