ABSTRACT:
An improved planetary grinding apparatus is described that comprises a grinding tube holder that carries removable grinding tubes. The grinding tube holder undergoes planetary rotation and simultaneously contra-rotates at the same rate about its own axis so as to have no net rotation with respect to the base of the machine. The grinding tube holder is rigid and has no supporting or other structures around it in the space between its ends. As a result of this feature, and because of the lack of rotation of the grinding tube holder, each grinding tube may be interconnected with fixed external connectors without the use of rotating seals.
