Abstract
A coffee mill comprises a coffee bean pulverizing cutter held in a mill casing, a space for catching skin slivers and fine fragments of coffee beans and a cutter receiving space communicated with the catching space. Air flow is produced between these spaces during pulverizing the coffee beans to move the skin slivers to the catching space.
