Abstract: A mining screening panel which has a screening surface having spaced stainless steel profiled wires supported on transversely extending spaced rods or bars in which the cross sectional shape of the profiled wires is a vertical truncated diamond. The top portion is an inverted wedge with a flat top with depending diverging sides and the bottom portion is a wedge with dependent converging sides with a flat or convex bottom. The widest portion of the vertical diamond constitutes the notional screening surface and defines the size of the screening aperture. The raised top above the notional screening surface provides the wire a wear surface above the aperture and this provides the wedge wire and aperture with a longer wear life, thus reducing change out periods and reduction in premature failure of wedge wire, which in turn reduces operating costs.
