Abstract
A rotary-type mill is provided with a system for charging powder to a mill under seal from atmospheric air, the system being comprised of a sealable loading conduit and a valve assembly. The valve assembly, which controls the opening to the mill, is disposed in part in the sealable loading conduit, and is operable without breaking the seal to the atmosphere. In addition to permitting charging and operations of the mill in a protective environment, the system is designed for gravity-dependent essentially unencumbered vertical entry of feed to the mill and for minimization of the problem of wear of machine parts during operation of the mill.
