The material is fed into the uppermost of a steppedseries of cup-shaped vessels, which are rotated ina horizontal plane upon vertical axes, and areprovided with wings on the under-side, extendingfrom the periphery down to the planetaf the bottomof the vessel. The vessels are rotated by suitablegearing in a casing or furnace chamber, and thematerial passes from one vessel to the next lowerone.âW. H. C.
