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.

Also provided is a vertical rotatable power driven shaft centrally located in said apparatus wherein a plurality of radially extending arms are fixed thereto and are rotatable with the shaft. Some of said separating pins are fixed to the arms and some cooperating separating pins are fixed to a disc plate also mounted about said power driven shaft. A rotating plurality of discs crush said soil to reduce large particles and destroy weed seeds, insects, and larvae.
