摘要

A screen panel for mining and quarrying industries adapted to be mounted on a screen deck, including a screening surface made up of materials such as herein described formed on a reinforcing frame, said screening surface having suitably designed apertures of desired shape for allowing materials of desired size to pass through, said apertures having walls (2) made of abrasion resistant material such as herein described, whereby retention of said desired shape of said apertures is ensured for a substantially long period of time.

主权项

1. A screen panel for mining and quarrying industries adapted to be mounted on a screen deck, including a screening surface made up of a material including at least one of mild steel, stainless steel, rubber, and polyurethane formed on a reinforcing frame, said screening surface having apertures shaped for allowing materials of a predetermined size to pass through, said apertures having contiguous walls spanning a length of the aperture and extending between a surface of the screen panel opposite the reinforcing frame and the reinforcing frame, wherein each wall is made of a material having a greater abrasion resistance than the screening surface for retaining the shape of the apertures,
wherein said metallic lining forms a metallic wall of said aperture with a slit cut along a vertical line, thereby enhancing the flexibility of said apertures and also ensuring wear protection.
