A device for grinding coffee beans (12) includes a grinding member (14) configured to grind coffee beans (12) and produce a ground coffee powder (15). A transit chamber (16) receives the ground coffee powder (15). A discharge member (18) is configured to discharge the ground coffee powder (15) arriving from the transit chamber (16) toward the outside of the device. An air-powered powder removal member (20) removes the ground coffee powder (15) from the grinding member (14) and from the transit chamber (16).

The present invention provides a coffee grinder, which comprises a storage chamber for storing coffee beans; a driving assembly having an output shaft; a grinding cartridge; a grinding assembly comprising a grinding wheel rotatably fitted in a grinding base so as to grind coffee beans therebetween; a control circuit board; one or more battery electrically connected to the control circuit board; and a powder receptacle; wherein, the grinding cartridge is longitudinally connected and communicated with the storage chamber at a top end and the powder receptacle at a rear end; the grinding assembly is installed in the grinding cartridge; and the driving assembly is longitudinally disposed in the storage chamber with the output shaft coupled to the grinding assembly to drive the grinding wheel to rotate.

A spice mill includes a main body with an internal cavity and a cap removably coupled to the main body to selectively provide access to the internal cavity. A drive shaft extends at least partially through the main body, with the cap transferring rotational motion to the drive shaft. A first grind stone is coupled to the main body and a second grind stone is coupled to the drive shaft. An adjuster assembly is at least partially received in the second grind stone to vary a size of a gap between the first and second grind stones. The second grind stone rotates relative to the first grind stone to grind a material received from the main body and output the ground material through the gap on sides of the spice mill.

A device and related method for reducing coffee beans into powder includes a primary tank or hopper for containing the coffee beans, a grinding chamber, one or more unloading ducts for unloading coffee powder from the grinding chamber, a ground coffee collecting zone, and a system for the manual or automated removal of coffee powder residues and of accumulations thickened inside the grinding chamber, on the surfaces of the members involved in the pulverization, and on channels of the coffee into the unloading ducts using gas introduced into the grinding chamber.

A grinder assembly which minimizes deviations in the path of ground material as well as other interfering structure is provided. A receiving chamber is disposed above a grinding mechanism and provides for direct transfer of material to be ground from the outlet aperture of the receiving chamber to the grinding mechanism. The grinding mechanism is driven from above and, therefore, no other structure necessary which may interfere with the ejection of grounds from the grinder assembly. A vacuum-stabilized base plate may also be provided in order to securely and removably mount the grinder assembly to a surface.

What is described is a new grinder, which serves to grind coffee beans and which is embodied as disk grinder. To improve the grinding process, the first and/or second grinding disk, respectively, encompass grinding surfaces that may define an angle of inclination, which may be in each case greater than 90? and smaller than 180?, relative to a tool reference plane.
