PROBLEM TO BE SOLVED: To provide a coffee grinder which comprises two rotatable grinding disks for setting a degree of grinding of coffee powder to be produced by an axial distance between the disks.SOLUTION: Griding disks 4, 5 are laid one over the other within a grinder body 1. The lower grinding disk 5 is rotatable about a vertical axis 6 of rotation while the upper grinding disk 4 is not rotated relative to the lower grinding disk 5 but can be adjusted to move by an eccentric shaft 13 in a direction of the vertical axis 6 of rotation. By rotating the eccentric shaft 13 with a motorized device 17, a space between the grinding disks can be changed to adjust a degree of the grinding.
