METHOD AND APPARATUS FOR CONTINUOUSLY CRYSTALLIZING POLYESTER MATERIAL |
摘要 |
Polyester granulates, in particular slowly crystallizing adhesive copolyesters are crystallized in two fluidized beds (1, 2) arranged in series and are guided into an impact apparatus (3) for the subsequent comminution of the small agglomerates. The first fluidized bed (1) is an effervescent fluidized layer with mixing characteristic and the second fluidized bed (2) is a flow bed with a plug flow characteristic. The second fluidized bed (2) ensures an adequate treatment duration in order to crystallize the amorphous grains of granulate which remain after the first fluidized bed (1).
