ABSTRACT:
Apparatus for simultaneously grinding coal and dolomite to a size suitable for fluid bed combustors in which the grinding mill is modified to allow for the formation in the mill of a bed of the mixed coal and dolomite which reduces the tendency of dolomite to fracture and produce excess of fine particles thereby optimizing the grinding conditions for both coal and dolomite, and a method of reducing coal and dolomite simultaneously in a common mill and in predetermined proportions for optimum reduction of each material.
