<p>A machine (10, 110) for sorting particulate material, which includes feed apparatus (12, 412, 512, 612, 712) for providing a continuous feed of particulate material, and having an inlet (20) and an outlet (22); rotor apparatus (14, 114, 414, 614, 5114, 6114, 7114) arranged beneath the outlet (22) and mounted for rotation about a vertical axis so as to accelerate incoming constituent particles of the particulate material fed thereto via the outlet (22) of the feed apparatus (12, 412, 512, 612, 712) in directions outward relative to the vertical axis, along helical trajectories (46, 120) whose respective radial distances from the vertical axis at different elevations generally correspond to preselected physical properties of the particles, wherein the particles are subsequently allowed to fall generally downwards; apparatus (55) for rotating the rotor apparatus at a rotational speed preselected in accordance with the type of particulate material sought to be separated, and collector apparatus (16, 416, 516, 616, 716) for dividing the falling particles into groups, each having different characteristic properties.</p> |
