Abstract

A tube mill for dry grinding of a granular material, the mill being formed with one or more grinding compartments charged with grinding bodies and, downstream of the first or sole grinding compartment, a relatively short compartment bounded downstream by a dam ring having a central opening and upstream by a sieving diaphragm for holding back the grinding bodies, but permitting fluidized ground material to flow from the upstream grinding compartment to the short compartment and vice versa, the short compartment being adapted to serve as a reservoir of fluidized ground material.
