Abstract
A granulating device having a cutting knife head for cutting strands of melt into granules in a granulator housing. A perforated plate with die openings, from which strands of melt is extruded into the granulator housing, projects into the granulator housing. The cutting knife head, which has at least one cutting knife arranged radially on its outer circumference, is driven by a rotating drive shaft. The granulator housing has a first coolant inlet and an outlet for a mixture of coolant and granules. In addition, the granulator housing has a second coolant inlet that is independent of the first coolant inlet and that supplies a coolant flow for direct granule cooling to at least one co-rotating cooling nozzle bore in the cutting knife head through a coolant chamber and a stationary coolant pipe oriented coaxially to the drive shaft.
