Abstract
A machine for the classification, sieving and separation of non-homogeneous masses of materials comprises a feed (12) for such non-homogeneous masses (11) and a discharge (13) for a coarse portion of material (11A), respectively arranged at opposite ends of a selection bed (14) of the non-homogeneous masses (11) comprising a plurality of rotary elements (15) arranged adjacent to each other and suitable for determining the movement of the material, in which the rotary elements (15) can be spaced apart by a predefinable amount to define passage ports (16) for a portion of material (11B) of predetermined shape and size of the non-homogeneous masses and in which the rotary elements (15) have a cross section with cam profile (17, 18) or variable radius, in other words having a different cross section to the cylindrical section, the cam profile (17, 18) being suitable for developing a sinusoidal peripheral speed of the rotary elements (15).
