摘要

The grinder (2) has a set of grinding blades (14) mountable on a rotatory and eccentrically drivable grinding plate (10) in a removable and exchangeable manner. The grinding plate exhibits a polygon shape (20), round peripheral shape, six or eight corner shape on its plate plane that faces the grinding blades in a top view.
