AI Technical Summary

Problems solved by technology

Hard chrome treatments are expensive and only available up to 125 microns thick and due to the condition of the coating (possibly uneven) results in a higher wear area which shortens plate life

Embodiment Construction

[0017] like figure 1 and figure 2 As shown, a conventional wedge wire plate consists of a screening surface of a stainless steel flat top wedge welded to an underlying support bar. The screen openings are defined by the spaces between the upper ends of the flat-topped wedges. The screening panels are surrounded by a polyurethane frame incorporating the desired fixing system around the perimeter of the screening surface.

[0018] An improvement of the present invention is to provide a truncated diamond wire profile, and examples of these truncated diamond wire profiles are shown in image 3 .

[0019] To manufacture the plate, the first step is to form the wire cross-sectional profile. Stainless steel wire is usually round and wound onto a drum, and in order to form the desired cross-section, the wire needs to be cold drawn (drawn) through a die that is usually formed on the surface of two mating wheels and has The shape or contour in the circumference of a wheel.

Abstract

A mining screening panel which has a screening surface consisting of spaced stainless steel profiled wires supported on transversely extending spaced rods or bars in which the cross sectional shape ofthe 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 notionalscreening 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.

Description

technical field [0001] The present invention relates to improvements in ore screening panels for separation and classification of materials in the mining and quarrying industry. Background technique [0002] Australian Patent 482212 proposes a modular screening panel system for ore screening panels which is now widely used in the mining industry. The screening panels are all the same size (eg 300mm) and made of reinforced polyurethane. The plates are adapted to be secured to the underlying support frame by means of dependent spigots which are press fitted into corresponding holes in the support frame. Patent 517319 provides an alternative method of securing the panels to the frame using the principle of pin expansion fastening. [0003] Australian Patent 724980 discloses a polyurethane panel having a screening surface defined by spaced screening ribs mounted on transversely extending support ribs and additional surface protection ribs extending above the screening surface....
