Abstract
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.
