Abstract (en)
The disclosure relates to a cutting knife (100) for a cutting shaft (24) in a comminution apparatus (10), said cutting knife (100) being a one-piece element comprising a base part (110) and one or more replaceable knife tip parts (120,120'), wherein each knife tip part is integrally formed with the base part at connection regions (130a,130b) at an outer periphery (104) of the one-piece element and is partly separated from the base part by an associated elongate through-opening (140,140'), said elongate through-opening: having an elongate extension (141,141') in the main plane (102), being spaced from said outer periphery (104), and being located so as to facilitate replacement of the knife tip part (120) by reducing the cutting required to separate the knife tip part from the base part. The disclosure further relates to a method for replacing a knife tip of such a cutting knife, and a knife tip replacement part for use in said method.
