Disk screen apparatus and disk assemblies therefore wherein each disk assembly comprises an elongate shaft adapted to be rotatably mounted in the disk screen apparatus. The shaft has elongate indexing and keying structure extending longitudinally along and rigid with the shaft and providing a longitudinally extending and circumferentially facing edge. The edge has a series of longitudinally spaced circumferentially extending indexing and keying notches therein. Annular screen disks are mounted on the shaft and have inner diameter key shoulders engageable in the notches. The keying structure may be raised along a longitudinal area on the cylindrical perimeter of the shaft or recessed along such area. A releasable locking bar is adapted for locking the key shoulders in the notches. |
