Abstract
A mill for grinding a spice or grain material has a grinding mechanism including: a lever mounted for pivotal movement about a lever axis, a grinder bit mounted for rotational movement about a grinder bit rotational axis, the grinder bit rotational axis being at least approximately parallel to the lever axis, and a linkage coupled to the grinder bit and coupled to the lever to transfer pivotal movement from the lever to the grinding bit. The grinder bit may be cylindrical and include a gradated set of teeth. A cam pivots an engagement surface to adjust a spacing between the engagement surface and the grinding bit to select a size of resulting particles.
