Of the many designs of ball mill that are available, two have become well adapted for the manufacture of lead oxides—the cylindrical `Shimadzu' type, and the conical `Hardinge' type (Fig. 6 Fig. 7). Both operate on similar principles and control parameters with slightly different product characteristics which depend upon the mill design used.
