Abstract

1343431 Vibratory screens BBA GROUP Ltd 13 Jan 1971 [21 Jan 1970] 2953/70 Heading B2H [Also in Division B5] A polyurethane screen formed by casting comprises a reinforcement of metal rods or wire or plastics mesh. Where metal rods are used, the edges of the screen are reinforced to facilitate mounting of the screen on to a vibrating frame, e.g. by bolting or riveting the screen through the rod to the frame. The apertures in the screen may be of any suitable cross-section, e.g. circular, square or elliptical and may be cylindrical or partially or completely tapering.
