摘要
When starting an underwater granulator, difficulties often occur since some of the melt delivery dies of the perforated disc (2) clog upon entry of the cooling water (flooding) into the granulating hood due to freezing of the polymer melt. …??Starting without freezing of the melt in the dies (2') of the perforated disc is achieved by carrying out cooling water feeding during starting in such a way that a water ring is formed on the inside wall of the granulating hood (1), the mixture of starting granules and water thereby produced being directed to a starting tank (9) via a starting deflector (8) at the beginning of the aftertreatment section. After reaching an adequately high melt throughput in the dies of the perforated disc, the transition to underwater granulating takes place by flooding the granulating hood. …IMAGE…
