Disclosed is a device for cooling, granulating and drying molten strands of synthetic thermoplastic material emerging from dies. It comprises a cooling unit which feeds the strands into a bath of cooling liquid and to which is connected a granulator housing with a cutting roll, the latter being connected to an outlet duct with a sieve to separate the thermoplastic material from the cooling liquid. The sieve is arranged in such a way that the grains separated from the strands by the cutting roll impinge directly on the sieve at basically the same speed as that imparted to the grains by the cutting roll.
Dispositif pour le refroidissement, la granulation et le séchage des brins en thermoplastique fondu à la sortie des filières. Le dispositif comprend une unité de refroidissement qui achemine les brins dans un cuve de liquide de refroidissement et qui est raccordée à un boîtier de granulation muni d'un rouleau de coupe, ce dernier étant raccordé à un conduit de sortie muni d'un tamis pour séparer le matériau thermoplastique du liquide de refroidissement. Le tamis est arrangé de manière telle que les grains qui sont séparés des brins par le rouleau de coupe arrivent directement sur le tamis, essentiellement à la même vitesse que celle communiquée aux grains par le rouleau de coupe.
