Abstract
A system is described for the production of rapidly solidified powder. The system contains elements for casting rapidly solidified ribbon, an in-line knife mill or a hammer mill for fracturing the rapidly solidified ribbon into shard, and either an in-line fluid energy mill, or an in-line centrifugal mill for reducing the shard to powder. The system can effectively reduce ribbon to powder in an in-line operation, and produce a powder with a particle size of -31 35 mesh. A method employing the system is also described.
