  • Horizontal ore filter with replaceable filter elements
    Patent number: 8252181
    Abstract: The horizontal ore filter has a plurality of filter elements covering the circular filter surface thereof and a sub-frame supporting the filter surface. In one aspect, each filter element has a longitudinal concave curvature therein. In another aspect, each sector frame has side flanges thereon. The sub-frame has a plurality of T-bars extending radially along the circular filter surface and each one of these T-bars supports the side edges of two adjacent filter elements. Upon installation of the filter elements to the sub-frame, the sector frames are held tight against the T-bars to ensure a good seal between adjacent filter elements and between each filter element and the sub-frame of the machine.
