Abstract
The invention relates to a twin-flow beater mill for preparing fibrous materials to produce intermediate products capable of further processing. It consists of a rotor fitted with beater plates surrounded by a cylindrical grinding surface. The rotor includes rotor plates which carry the beater plates and which form a guide duct, shaped like an annular disk, which opens out peripherally onto the center of the grinding surface. The beater plates are interrupted on the inlet side in the opening-out region of the guide duct, and on the outlet side replaceable retaining rings can be set on the two end faces of the grinding surface so as to variably adjust the classifying effect.
