The invention relates to a device for producing granules from a melt material, comprising a perforated plate (2) that has nozzles located therein (1) out of which said melt material leaves and, lying opposite said perforated plate (2), there being a cutting arrangement which comprises a blade head with at least one blade (3), and a blade shaft (5), driven by a motor. The device comprises a cutting chamber (7) in a housing (6, 6a, 6b) which chamber is attached to the perforated plate (2), surrounds at least the at least one blade (3) of the cutting arrangement, and has a cooling medium passing through it. A cooling medium centripetal flow is formed at least in the region of rotation, and said cooling medium and the granules present therein are subsequently fed to an outlet (11) of the cutting chamber (7). The inflow nozzle arrangement (9) is designed as an annular slotted nozzle that can be adjusted in terms of slot width. |
