ABSTRACT:
A gearing arrangement for a grinding apparatus, especially a bowl-type grinder or grinding mill, comprises a lower housing portion and an upper housing portion secured to the lower housing portion. At the upper housing portion there is rotatably mounted a support or mounting plate for a grinding bowl or receptacle. This support or mounting plate is mounted at the upper housing portion for rotational movement about a substantially vertical axis of rotation. The support or mounting plate is driven by angular gearing, for instance bevel gearing, and planetary gearing arranged in the lower housing portion. The planetary gearing contains an outer central gear which is arranged upon the lower housing portion as a part of the upper housing portion and is constructed as a support ring of an axial bearing for the support or mounting plate.
