An herb and spice grinder has a plurality of sections that are removably connected together. A hole is formed at the outer periphery of each of the plurality of sections. The plurality of sections can be rotated relative to one another so that the holes align to form a passageway. The bolt of a lock can be inserted through the passageway so as to prevent the sections from rotating relative to one another and to prevent the sections from being separated from one another. As a result, undesired access to the contents of such herb and spice grinder is effectively prevented. Preferably, rotation of a top section relative to an intermediate section causes a grinding of the herb or spice. The ground material passes through openings in the intermediate section to be stored in a receptacle formed in a bottom section. A blade for a grinder is also disclosed.

A grinding device includes: first and second grinding elements, the first grinding element being rotatable relative to the second grinding element around a rotary axis for grinding coffee beans between the grinding elements into a powder; a carrier wheel rotatable around the rotary axis for conveying powder on the carrier wheel to an outflow channel to output the powder; a housing surrounding the grinding elements and the carrier wheel and including the outflow channel, the second grinding element being stationary relative to the housing, a rolling bearing with inner and outer rings and rolling elements therebetween, the outer ring being stationary on the housing and the first grinding element, the carrier wheel and the inner ring being rotatable around the rotary axis together. An annular seal ring seals an intermediate region above the outer ring around the rotary axis between the carrier wheel and the outer ring.

A grinding device comprises a grinding housing with mutually co-acting grinding bodies. A lower of the two grinding bodies is both driven and axially adjustable for the purpose of setting a grind size. An upper grinding body is removable. A grind size of the grinding device can be adjusted in absolute manner between a first extreme position and a second extreme position, corresponding to a fixed setting range between a minimal clearance between the two grinding surfaces and a maximum clearance between the two grinding surfaces. An extreme position of the adjustable grinding body is imposed by a stop which is encountered by the adjusting means in the relevant extreme position. A coffee machine uses the absolute grind size and/or a fine-tuning for an optimal contact time between coffee and through-flowing water.
