Abstract
Stackable screening plates (3) with radial screening apertures (10) are carried on a tubular shaft having an axial key. The plates have a choice of keyways (14, 15) allowing the plates to be stacked in alternate angular positions. Spring tongues (16) formed integrally with the plates provide uniform but adjustable mutual spacing.
