Abstract: A method of wet granulation of fertilizer and other materials into granules. The method involves formation of the granule directly on the pan from the feedstock without intermediate steps or the use of seed materials. The result is a product having a completely uniform cross section. The feedstock is initially in the size distribution of −150 mesh with 90% or greater in the size range of 200 mesh. Moisture is maintained to facilitate a steady process without cycling. The method has the advantage of allowing granulation of materials either known to be hazardous or inherently difficult to granulate in a safe and expedient manner. The process permits the formation of multiple feedstock granules. The initial feedstock may be augmented with a different feedstock in a second pan having a different composition and size from the initial feedstock.

Abstract: A method and apparatus for sizing a galvanized tube, in which two sizing stations are used. A first sizing station having at least one sizing roll is used for sizing the tube prior to the galvanizing process. A second sizing station is then used, the station having at least one resilient sizing roll which is used for sizing the tube after the galvanizing process.
