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.

Abstract: A modular exciter beam fitted to a vibratory screen assembly. The exciter beam spans between opposing side walls of the screen assembly. The modular exciter beam provides mounting for a pair of exciter mechanisms which are located substantially inside the side walls of the screen assembly.

Abstract: A system for monitoring screening facilities which includes screening panels and components of the screen deck incorporating wirelessly readable identification tags; a computer database containing information relating to the screen deck components and their associated tags; a wireless tag detection station for regularly reading the conveyed material to detect tags; a computer program for matching the detected information with said data base and means for communicating a warning that a screen deck component has been dislodged.

Abstract: A modular screening panel in which the apertures in the screening surface extend through the surface and the shape of the aperture parallel the plane of the panel surface varies with the depth of the aperture so that as the surface wears the visible shape of the aperture changes. The apertures can be any convenient shape at the surface but at the depth which means the worn panel needs replacing the shape is distinctly different to the shape of the apertures in a new or partly worn panel.
