A disk screen or like shaft structure in which screen disks and spacers are connected together in modular relation. The spacers support the disks with inner edges of the disks spaced from inner surfaces of the spacers so that when the modules are supported on a shaft the inner edges of the disks will be maintained spaced from the shaft. The spacers are preferably made from nonmetallic material such as polyurethane. By placing the modules under predetermined endwise compression, the inner surfaces of the spacers are adapted to be extended inwardly from an initial edge relation generally aligned with the inner edges of the disks. Bolts may serve as the connectors for the disks and spacers for the modules, and facilitate assembling of the modules under endwise compression.

A disk screen or like rotatable shaft assembly, comprising: an elongate metallic shaft member; a plurality of metallic disks mounted corotatively on said shaft member and having central shaft-receiving openings complementary to said shaft member but of sufficiently larger size so that edges defining said openings can be in substantially uniformly spaced relation to the shaft member; nonmetallic spacers between said disks and with inner edge surfaces of the spacers extending inwardly beyond said edges defining said openings and engaging the shaft member; and means for connecting said disks and spacers together into a modular unit which can be slidably mounted on or removed from the shaft member, and the spacers supporting said disks in cooperation with said connecting means on said spacers with said edges defining said openings substantially uniformly spaced from the shaft member.
