CENTRIFUGAL SCREEN APPARATUS

摘要

There is provided a centrifugal screen including a screen support (11) mounted on a drive plate (12) for driven rotation within a housing. The screen support (11) is formed from hoops (13) interconnected by stringers (14). Six modular, part-conical screen modules (30) are formed from a wedge wire (31) welded to transverse bars (32), cut to shape and pressing to part conical curvature. Locating lugs (33) are welded to the bars (32) adjacent the module side edges. The module (30) has a wear resistant sleeve portion (35) which engages the drive plate (12). The outer end (37) of the module (30) has a peripheral flange (40). The hoops (13) are each provided with pairs of slots (37) adapted to receive the round-bar locating lugs (33) adjacent the side edges of each of the screen modules (30). The flange (40) engages with the outer terminal hoop (21) as the sleeve portion (35) engages the drive plate (12) and is secured with metal threads (41).
