Abstract (en)
[origin: EP0067402A1] 1. Grinding head for hard stone, having a vertical drive shaft, which sets the grinding head in rotation, and having grinding bodies (1) which are circular in cross-section and rotatably mounted, which grinding bodies (1), by means of their surface line (11) facing towards the hard stone surface to be ground, define a plane (3), with the grinding bodies (1) being arranged eccentrically in such a way that the surface lines (11), defining a plane (3), of the grinding bodies (1) are pointed tangentially past the centre formed by the intersecting point of this plane (3) with the axis (2) of the drive shaft, characterised in that the grinding head is rigidly connected to the vertical drive shaft, and the grinding bodies (1) are arranged so as to be freely rotatable in the grinding head.
