Abstract:
1. An apparatus for sorting particles of a material, comprising: a frame; a drive assembly attached to the frame to induce gyroscopic vibratory motion of the frame in a selected rotational direction; adjacent first and second inclined screens affixed to the frame, the screens each sloping downwardly away from an intermediate ridge, wherein the first inclined screen extends at a first angle with respect to a horizontal plane and the second inclined screen extends at a different, second angle with respect to the horizontal plane; wherein material dropped onto the intermediate ridge separates into a first stream passing along the first inclined screen and a second stream passing along the second inclined screen; wherein the first and second angles are selected in relation to the vibratory motion of the frame so that the first and second streams each move at substantially the same velocity along the respective first and second inclined screens; and wherein the intermediate ridge comprises a diverter member with opposing first and second radiused surfaces to transition the flow of the material from an initial substantially vertical flow into the respective first and second streams.
