摘要： Disclosed is a vibratory screening machine comprising a frame, a pair of screens mounted in the frame one beneath the other, electromagnetic vibrating drives, and two sets of pushers. Located in the frame are stops rigidly secured in relation thereto. The pushers of the first set are connected to the vibrating drives and make contact with the screen closest to the drives. The pushers of the second set are positioned within the guides in alignment with the pushers of the first set and spring-loaded against the stops in the direction of said pushers of the first set.

摘要： 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.

摘要： A vibratory screening machine comprises a frame, at least two screens with meshes of different size arranged in the frame one above the other, pushers hinged to a support in the interscreen space, and vibrating drives for imparting vibrational movements to the pushers. Each pusher is formed by two levers hinged each, at one end to the support, the other end of each lever making contact with one of said screens, and an elastic element being disposed between the levers.
