| 摘要 |
The invention relates to a comminuting device comprising a cylinder casing which surrounds a comminuting chamber, in which several rotors (30, 32, 34) can be operated independently from each other with individual drives, said rotors being driven by concentric shafts (14, 16, 18) which are arranged concentrically to the central axis (z) of the comminuting chamber, said concentric shafts having a central shaft (14) and at least one outer hollow shaft (16, 18) surrounding said central shaft. At least one lubricant line for connecting to a lubricant supply (66) is arranged in the central shaft (14) and/or in a shaft casing, said said lubricant line being connected by means of at least one radial lubricant through guide (68) to at least one bearing (22, 26, 28) of the rotors. |
