An oscillating screen (10) comprises a screening container (12) inside which a screening means is disposed lying on a determinate screening plane (P), coinciding or inclined with respect to a horizontal oscillation plane (X), and oscillation means (18, 26) to move the screening container (12) with respect to a fixed supporting structure (15). The oscillation means (18, 26) comprises a first movement unit (18) provided with a first rotary shaft (20) associated with a first eccentric element (24) cooperating with the screening container (12), and a second movement unit (26) having at least a second rotary shaft (40) provided with a second eccentric element (28) cooperating with the screening container (12). A transmission means (30) connects the first rotary shaft (20) and the second rotary shaft (40) with each other, so that they have the same angular velocity. |
