Abstract

A granulation process achieving tight size distribution and homogenous composition comprises: a) adding liquid to a powder in a mixer; b) first mixing the liquid and binder to form intermediate granules; c) selecting intermediate granules while wet that are larger than a predetermined diameter from smaller granules; d) crushing said intermediate granules to a size less than said predetermined diameter; e) second mixing said crushed granules with said smaller granules while still wet until granulation is complete. The crushing of the larger granules serves to redistribute the binder.
