Abstract
An apparatus for grinding a mineral includes a head operable to be attached to a bottle. The head includes a radial slider for controlling the coarseness of the grind. The apparatus further includes an inner grinding element, an outer grinding element, a shaft, and a neck sleeve. The inner grinding element is in communication with the head. The outer grinding element is also in communication with the head, wherein the outer grinding element and the inner grinding element are operable to rotate relative to each other. The shaft extends through the inner grinding element and the outer grinding element. The shaft couples with the inner grinding element and has a blunt end. The shaft also extends through the neck sleeve, which acts as a spacer between the inner grinding element and the blunt end.
