Abstract
A screening machine comprising a plurality of rotors adapted such that in a frame the axes of the rotors are arranged parallel to one another from a supply side where objects to be screened including mixed substances different at least in size are supplied from above by a conveyor to a discharge side where the remainders after screening are discharged, and such that the rotors are rotated in the same direction by a rotating drive, each rotor further comprises at least two kinds of components, namely, a plurality of large diameter sections and a plurality of small diameter sections alternately disposed in the axial direction of each rotor and arranged in a staggered relation in the feeding direction to define screening gaps having desired dimensions between the large and small diameter sections.
