Comminuting device
First Claim
1. A comminution device comprising a cylinder surrounding a comminution chamber, in which a plurality of rotors are driven independently from each other by their own drives, the plurality of rotors are driven via a plurality of concentrical shafts which are arranged concentrically to a central axis (z) of the comminution chamber, the plurality of concentrical shafts comprises a central shaft as well an outer hollow shaft surrounding the central shaft, whereby in the central shaft at least one lubricant pipe connected with a lubricant supply is arranged, the lubricant pipe is connected with a plurality of bearings of the plurality of rotors via a radial lubricant duct, wherein the plurality of concentrical shafts comprises in the area of the plurality of concentrical shafts'"'"' lubricant ducts, one radial extending lubricant channel which abuts to a wall of the plurality of concentrical shafts in an area of the the plurality of concentrical shafts lubricant ducts located therein.

Abstract
The invention relates to a comminuting device including a cylinder casing which surrounds a comminuting chamber, in which several rotors can be operated independently from each other with individual drives, said rotors being driven by concentric shafts which are arranged concentrically to the central axis (z) of the comminuting chamber, said concentric shafts having a central shaft and at least one outer hollow shaft surrounding said central shaft. At least one lubricant line for connecting to a lubricant supply is arranged in the central shaft and/or in a shaft casing, the lubricant line being connected by at least one radial lubricant through guide to at least one bearing of the rotors.
