Abstract
A centrifugal pellet dryer screen (540) especially adapted for drying polymer pellets and micropellets includes an exterior or outer support screen (542), an inner screen (546) of an irregular or rough surface, and an optional middle screen(s) (544) sandwiched between the outer support screen and the inner screen. The screen layers are in intimate contact and the multi-layer screen assembly produces drier pellets and micropellets exiting the dryer. Plugging of the dryer screens and banding of the pellets or micropellets are significantly reduced.
