  • Screen panel fixing system
    Patent number: 5769241
    Abstract: A system for fixing screen panels to a screen deck frame of an ore screening apparatus. An elongate fixing rail extends over the screen deck frame along and between side edge regions of a pair of adjacent screen panels. The fixing rail, in use, is non-interconnecting with the screen panels. An elongate retaining strip extends along the fixing rail, and engages the side edge regions of the screen panels in an overlying relationship. The retaining strip is connectable to the fixing rail so that the retaining strip secures the screen panels in position against upward movement away from the screen deck frame.
