Abstract
A coffee grinder which may be used in the hotel industry is positioned at an oblique angle to the vertical and makes it possible for several coffee grinders for different types of coffee to be accommodated in a minimal space. Coffee beans are fed into a grinding mill having fixed and rotating grinding wheels. The distance between the grinding wheels is adjustable. An ejection opening for discharge of the ground coffee powder allows the powder to be ejected tangentially and under the influence of gravity from the grinding mill.
