A spice grinder is comprised of a mounting ring for screwing onto a spice container. An outer grinding member comprised of a ring is locked to the top of the mounting ring to prevent rotation. An inner grinding member comprised of a cone is positioned within the outer grinding member. A cap is positioned around the outer and inner grinding members, and rotationally fixed to the inner grinding member. An adjustment knob is attached to a shaft which is positioned through the cap and the inner and outer grinding members. A first spiral ramp under the knob is engaged against a second spiral ramp on the cap. An inner end of the knob is locked to the inner grinding member. Spring arms projecting radially from the inner grinding member are biased against an inner surface of the cap. Coarseness is adjusted by rotating the knob.
