Abstract
An apparatus for granulating plastic is described, comprising a granulating head (1) with nozzle bodies (2) which are inserted in the granulating head (1) and protrude axially beyond its face, and a perforated plate (5) placed axially in front of the granulating head (1), the pass-through holes (6) of which receive the protruding nozzle bodies (2) by interposing a ring seal (10) with play. In order to provide advantageous cutting conditions it is proposed that the nozzle bodies (2) are flush with the perforated plate (5), and that the ring seals (10) are held in a pretensioned manner in the radial direction between the walls of the pass-through holes (6) and the nozzle bodies (2).
