  • Method and apparatuses for screening
    Patent number: 8561803
    Abstract: A method and apparatus are disclosed for screening materials. A vibratory screening machine includes a first frame and a second frame. The second frame is attached to the first frame by elastomeric mountings. A vibratory motor is configured to vibrate the first frame and the second frame. An attachment arrangement is configured to secure a replaceable screen assembly to the first frame. The replaceable screen assembly is in contact with the second frame such that the second frame excites the replaceable screen assembly.
