The invention relates to an arrangement with an extrusion die ( 1 ) of an extruder for granulating plastic material with several pass-through openings ( 4 ) for allowing the passage of plastic melt, and a granulating die plate ( 2 ) with holes ( 3 ) arranged on its die face ( 1 '), with the pass-through openings ( 4 ) each opening into a separate nozzle-like projection ( 6 ) protruding beyond the front die face ( 1 ') of the extrusion die ( 1 ), with the free cross section of the holes ( 3 ) being larger than the outside circumference of the projections ( 6 ) for the contactless reception of the nozzle-like projections ( 6 ) in the holes ( 3 ) of the granulating die plate ( 2 ) by forming a clearance ( 7 ), and with an elastic sealing material ( 10 ) being arranged between a front face surface ( 8 ) of the nozzle-like projection ( 6 ) and a supporting element joined with the granulating die plate ( 2 ), preferably a holding flange ( 2 ') of the granulating die plate ( 2 ). In order to create advantageous conditions it is proposed that the nozzle-like projections ( 6 ) comprise a web ( 12 ) projecting beyond its face surface ( 8 ) at each of its inner sides delimiting the pass-through opening ( 4 ).
