ABSTRACT:
Disclosed is a vibratory screening machine comprising a frame, a pair of screens with meshes of different size, mounted within the frame one above the other, pushers formed by double-arm levers located in the interscreen space and hinged to a support, and vibrating drives for imparting vibrational movements to the pushers. The arms of each lever are made of different length and make contact with different screens, the longer arms contacting the screen with larger-sized meshes.
