CENTRIFUGAL PELLET DRYER SCREEN

摘要

A centrifugal pellet dryer screen especially adapted for drying micropellets includes an exterior or outer support screen in the form of a cylindrical perforated plate, an inner screen of small wire mesh material, and an optional middle screen of wire mesh material sandwiched between the outer support screen and the inner screen. The screen layers are preferably diffusion bonded to each other. These multi-layer screens produce drier micropellets exiting the dryer and reduce banding of the micropellets and plugging of the dryer screen outlet holes.
