<p>A vibratory particle separating apparatus (1) for separating a supply of particulate material into at least two streams according to particle size. The apparatus includes an inclined particle separating screening surface or surfaces (10), secured in a floating frame (21), which is seated in a support frame (20). The screening surface (10) is typically characterized by a landing (9) and multiple steps (11) disposed perpendicular to the path of material flow. The floating frame (21) is suspended in the support frame (20) by resilient float mounts (18, 19) and is vibrated along with the screening surface (10) by a vibratory motor (7) mounted on the floating frame (21). The particulate material is loaded on the inclined end, or landing (9), of the screening surface (10), and as the material cascades from the landing down the perpendicular or angular steps (11) of the screening surface, particles smaller than a selected size fall through one of multiple, adjacent openings (14) of selected size, shape and orientation provided in each step and are collected or discharged for further processing in a stream below the screening surface. Larger particles are collected or discharged in a separate stream at the foot of the screening surface.</p> |
