As a construction, a ball milling device usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel around the center axis. The mill is driven by a girth gear bolted to the shell of the
WhatsApp: +86 18838072829The ball ring mill has a mill housing, a grinding track (6) and grinding balls (7) which are activated by an outside force and run on the grinding track. For each grinding ball a separate pressure mechanism (8) is provided for transmission of the outside force on the grinding balls. Each pressure mechanism has a ball dome surface as pressure surface acting on the grinding balls.
