Abstract
A device for cooling, granulating and drying molten strands of synthetic thermoplastic material emerging from dies includes a cooling unit for applying a cooling liquid to the strands and a granulator housing with a cutting roll for granulating the strands. The granulator housing is connected to an outlet duct with a sieve to separate the thermoplastic material from the cooling liquid. The sieve is arranged so that the granules separated from the strands by the cutting roll impinge directly on the sieve at basically the same speed as that imparted to the granules by the cutting roll.
