A grinder comprises: a receiving container, formed with an accommodation space and an installation space, and the bottom end thereof being extended with a connection ring have a feeding port, and a hollow grinding seat and a fasten ring are respectively and detachably disposed in the feeding port and the connection ring; an electric driving device, detachably disposed in the installation space; and a base, detachably disposed at the bottom end of the receiving container and including a hollow grinding chamber having the interior disposed with a support member with a pivotal shaft, a passive rod is sleeved and linked with a conical grinding disk, the top end and the bottom end of the passive rod are respectively sleeved with the output shaft and the pivotal shaft, thereby allowing the grinding disk to protrude into the grinding seat and forming a gap between the above two.

A grinder for a spice mill, in particular a hand-operated spice mill, having an inlet side for entry of unground grinding stock and an outlet side for the exit of ground grinding stock, including a rotor, a stator interacting with the rotor and a housing at least partially surrounding the rotor and/or stator. The housing includes a stator housing part, which is substantially rotationally fixedly connected to the stator, and a rotor housing part which is rotatable relative to the stator housing part and is substantially rotationally fixedly connected to the rotor via a connecting element. The connecting element is at least partially received in a recess in the rotor, and the connecting elements and the rotor are frictionally connected. The housing has, on a side of the rotor facing the inlet side, a blocking element which blocks displacement of the rotor in the direction of the inlet side.

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 which is also tapered such that the sidewall surface interlocks with the side surface of the frustoconical burr.

A mill for granular food including an adjuster attached to a barrel unit and rotatable relative to the barrel unit and to be prevented from coming off the barrel unit in an axis direction. A ground particle size for granular food is adjusted by rotating the adjuster. A movement attachment and detachment unit that inscribes an outer mill unit in the barrel unit and the adjuster, and makes the outer mill unit movable in the axis direction and makes the outer mill unit attachable and detachable. A rotary shaft extending from a rotary operation unit extends downward along a mill. An inner mill unit is attached to the rotary shaft. The adjuster is provided with a movement restricting unit that restricts movement of the inner mill unit to a predetermined position. Releasing the restriction makes the inner mill unit and the outer mill unit extractable.

The present disclosure provides an apparatus for serving one or more purposes. The apparatus includes a case. The case has at least one coupling provision from a plurality of coupling provisions. In addition, the apparatus includes a holder operably coupled at one end of the case. The holder is used for holding at least one of a keychain, a ring, a band, and a bracelet. Further, the apparatus may include a band. The band is placed for holding at least one of a communication device or a hand of a user. Furthermore, the apparatus includes an operating module operable coupled with a mechanism that is positioned inside or around the case to control and operate a holding module. The operating module is positioned on any of face of the case. The holding module has a provision for mounting a plurality of elements for serving the one or more purposes.

The mill for spice products, in particular such as cinnamon sticks, houses a reservoir for storing the spice product. The reservoir communicates through a passage, with a grinding mechanism. The reservoir includes a mechanism for fragmenting the spice product. The mechanism for fragmenting are defined by a crusher of the spice product.

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr to an end, the shaft having an axis of rotation, and a burr having an external surface, the burr having an internal bore that extends therethrough. The internal bore has a surface which is tapered with respect to the axis of the shaft. An interlocking plug is shaped to extend through the internal bore of the burr, the interlocking plug having a sidewall surface which is tapered with respect to the axis of the shaft, such that the sidewall surface abuts the surface of the burr to seat the interlocking plug within the burr. An adjustment knob engages the end of the shaft for locking the interlocking plug within the burr.
