<p>The invention relates to a device (10) for reducing granulate-type debris, especially particles of bone, by crushing, comprising a crushing drum which is located in a housing (12, 18) and which has a strainer-type perforated drum shell (50). Said drum can be moved around its drum axis by means of a rotating device (42) located outside of the housing (12, 18). The drum shell (50) forms the floor of a feed shaft (48) provided in the housing (12, 18). A pressure body (58) which is able to move in relation to at least one energy accumulator (12) is provided in the feed shaft, said pressure body (58) being equipped with a pressure surface (60) which faces the drum shell (50) when it is in use. The diameter (d) of the drum shell (50) is greater than the width of the feed shaft (48) allocated to the drum shell (50). The feed shaft (48) is located in a cuboid-shaped socket part (12) of the housing (12, 18) with a channel (22) which crosses the axis of the shaft and receives the crushing drum.</p> |
