A grinder specially adapted for grinding herbs has a sheet with unique groove and hole patterns forming a grinding area. Although it is a manual grinder, the grinder does not require the use of cutting blades, making it much safer to use. The grinder is particularly suitable for grinding softer herbs.

A bean grinding apparatus including a body; grinding burrs mounted in the body, the burrs including a non-driven burr and a rotationally driven burr, the rotationally driven burr having a rotational axis about which it rotates; a drive motor operatively coupled to the rotationally driven burr; a grounds flow path defined within the body; and an exit spout, the exit spout having an inlet in communication with the grounds flow path and an outlet, wherein the exit spout defines a longitudinal axis and the longitudinal axis of the exit spout is angled with respect to the rotational axis of the driven burr.

The present disclosure provides a handheld household grinder, which comprises a housing having an accommodating cavity and a grinding rod is arranged in the accommodating cavity of the housing; the upper portion of the grinding rod penetrates through the housing until the grinding rod is partially exposed out of the accommodating cavity; a through hole is formed in the corresponding location of the housing underneath the grinding rod along the length direction, the lower portion of the grinding rod penetrates out of the accommodating cavity via the through hole or resets into the accommodating cavity via the through hole; the external lateral wall, proximal to the lower portion of the grinding rod is provided with a coarse surface, when the grinding rod drives the coarse surface on the external lateral wall of the grinding rod to move into the through hole.

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr, a frustoconical burr, and an interlocking plug. An internal bore of the frustoconical burr has an upper cylindrical surface adjacent the top end, an interlocking portion adjacent the bottom edge, and a tapered side surface. The interlocking plug is shaped to extend through the internal bore of the frustoconical burr, and includes an upper cylindrical portion that fits through the upper cylindrical surface, and a lower portion that includes a sidewall surface to which is also tapered such that the sidewall surface interlocks with the side surface of the frustoconical burr.
