  • Patent number: 9089877
    Abstract: A vibrating screen separator machine including a frame bounding a first screening assembly, the first screening assembly forming a first sifting plane. The first screening assembly comprises a mesh screen and a planar backing panel proximate the mesh screen, the backing panel having a plurality of perforations. The screen separator also includes a material input slot on the frame and an un-sifted material output slot and a sifted material output slot on the frame where material travels from the material input slot into the screening assembly and where un-sifted material exits the frame through the un-sifted material output slot and sifted material exits the frame through the first sifted material output slot. The screen separator also includes a vibration mechanism supported by the frame and connected to the screening assembly, the vibration mechanism imparting vibrational energy to the screening assembly to sift material passing through the screening assembly.
