Abstract
The invention relates to beater mills in the grinding chamber of which there rotates a beater rotor which is fitted on its circumference with beater tools and is surrounded by a cylindrical grinding surface adjoined by a coaxial centrifugal classifier. The centrifugal classifier is variably defined by retaining rings having different retaining rim heights, the rings bearing against the outlet-side end faces of the grinding surface so as to determine the classifying effects.
