  • High frequency screen with dual motor tappet assemblies
    Patent number: 11707767
    Abstract: A vibratory screen assembly includes a rigid frame having a pair of parallel side members that are spaced apart such that a space is provided between them. A tappet assembly extending horizontally across the space between the side members includes a horizontal member having opposing ends secured to the frame. A screen placed over the tappet assembly provides a screening medium having a mesh size. A vibrator motor is located at each of the opposing ends of the horizontal member to form a cooperative pair of vibrator motors that induce vibrations in the horizontal member and in the screen. As the screen vibrates, aggregate material that is smaller than the mesh size passes through the screening medium and aggregate material that is larger than the mesh size does not pass through the screening medium.
