Abstract
An oscillating screen comprises a screening container 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 to move the screening container with respect to a fixed supporting structure. The oscillation means comprises a first movement unit provided with a first rotary shaft associated with a first eccentric element cooperating with the screening container, and a second movement unit having at least a second rotary shaft provided with a second eccentric element cooperating with the screening container. A transmission means connects the first rotary shaft and the second rotary shaft with each other, so that they have the same angular velocity.
