Aug 25, 2006 · Ball mill (): Unlike the Barton process, the ball mill process is solid state—the feed stock consists of pieces of lead (pigs, shot, etc.) and the reactor is operated at temperatures below the melting point of lead.In the process, pieces of ultrapure lead are conveyed into a rotating ball mill. The lead pieces serve as both the feed stock for the reaction and the grinding media
