Abstract
A sectionalized screen/basket assembly for a centrifugal dryer for coal slurry comprises a screen formed in an upper section and a lower section, enabling one to save substantially on screen replacement costs, inasmuch as the great preponderance of screen wear in such dryers is at the top of the screen, at the point of slurry introduction. An internal circumferential ridge on the upper screen creates a particle cake that further reduces wear.
