| 摘要 |
<p>The invention concerns a device comprising a rotary shaft ( 2 ) supported above a layer (C) of material, transversely to the translation direction (A) of the material, and means for turning ( 3 ) the material extending at least partly radially relative to the shaft ( 2 ) and rotated by said shaft to penetrate into the layer. The device comprises means for cutting ( 4 ) the layer (C) of material, radially spaced apart (g) from the rotary shaft ( 2 ) and rotated by said shaft, said cutting means ( 4 ) being located substantially on a cylindrical surface sharing a common geometrical axis with the rotary shaft, and capable, upon penetration into the layer, of fragmenting the latter, while the turning means causes the fragmented material to be granulated.</p> |
