Abstract

PURPOSE:To form spheroidized thermoplastic resin simply and quickly by a method wherein thermoplastic grain dispersing air flow is blown from the upper wall part of a granulating tower into compressed hot air flow and cold air is supplied into the granulating tower. CONSTITUTION:When heated air 33 is ejected from a supply pipe 14 and thermoplastic grain dispersing air flow 34 is blown from a thermoplastic grain supply device into compressed hot air flow 33 through an introduction pipe 20, a distribution pipe 21, the thermoplastic grain dispersing air flow is heated in collision with the hot zone of the compressed hot air flow 33 near the inlet 25 of the granulating tower 13 shielded from the open air. Accordingly, the thermoplastic grains are softened, fused quickly and uniformly, the softened layer of the grain surfaces receives surface tension and is sent to the exhaust port 26 of the granulating tower 13 formed into uniformly globose grains. Since the side wall 28 of the granulating tower 13 is cooled partially, the grains are not fused or massed.
