摘要： The invention relates to a replaceable blade piece (1) of a working cylinder of a screen crusher, which as viewed from the side is substantially T-shaped. The blade piece has a frame portion (2) forming the vertical shaft of the T and a blade portion (3) forming the horizontal arm of the T, the longitudinally opposite front surfaces of which form the actual work surfaces (4). The frame portion (2) has a through hole (5) extending in the longitudinal direction of the blade portion (3). Into the frame portion (2) is formed, on the opposite sides containing the hole (5), a channel-like section (6), which extends in the vertical direction of the frame portion (2), between the edge areas (8, 9) of the side with the hole (5). The invention further relates to a replaceable blade piece holder (11) of a working cylinder of a screen crusher, said holder having a U-shaped frame portion comprising arm portions (12, 13), through which extends a longitudinal hole (15) of the frame portion, and a bottom portion (14) with a curved bottom connecting the arm portions (12, 13). On the opposite surfaces of the arm portions (12, 13), onto their middle area is formed a bulge (16), which extends in the vertical direction of the arm portion, travelling at the hole (15).

摘要： The invention relates to a crushing blade arrangement of a crushing drum, in which on the outer surface of the crushing drum are arranged a plurality of crushing blades. The arrangement includes, fixedly attached on the outer surface of the drum, a blade holder (1) with a receiving space (3) for an interchangeable blade piece (11). The blade piece (11) is composed of a horizontal blade portion (13) and a vertical shaft portion (12), which shaft portion (12) is adapted to be placed into the receiving space (3) of the blade holder and to be locked into it by means of a separate locking element. The receiving space (3) is shaped as an opening, which has on at least one side a locking protrusion (5) extending inwards to the opening. The shaft portion (12) of the blade piece (11) is shaped as substantially corresponding to the opening of the blade holder and equipped with a locking channel (15) corresponding to said at least one locking protrusion (5) and extending towards the interior space of the shaft, which locking protrusion (5) and locking channel (15) together form a form locking.
