ABSTRACT:
A pellet cooling system including a novel coolant cage construction and operational manner so as to insure the cooling of warm thermoplastic pellets as they emerge from a die head and are cut by rotating knives is disclosed. After cooling, as by entrainment in coolant flows simultaneously directed peripherally about the cage sides and radially across the front face thereof, the pellets are immediately withdrawn from the cage. Additionally, a feature of the coolant cage is the provision of a novel slinger for distributing a coolant flow evenly over its front face.
