• an upper housing portion secured to the lower housing portion;
• a mounting plate for a grinding bowl and having a substantially vertical axis of rotation;
• an axial bearing;
• a radial bearing;
• said mounting plate being mounted by means of said axial bearing and said radial bearing at said upper housing portion;
• angular gearing possessing a substantially horizontal drive shaft and a power take-off shaft arranged substantially coaxially with respect to said mounting plate;
• planetary gearing comprising:
• a sun gear coupled with the power take-off shaft of the angular gearing;
• at least one planetary gear;
• a planetary gear support connected with said mounting plate;
• and
• a substantially ring-shaped outer central gear secured to the lower housing portion;
• and
• said outer central gear being arranged as part of the upper housing portion upon the lower housing portion and being constructed as a support ring for the axial bearing.
