mixture of limestone and gypsum

Agglomeration of gypsum, limestone, or gypsum

A process is described for granulating finely-divided gypsum, limestone, or mixtures thereof to produce essentially non-dusty, hard, non-friable granular materials of a size suitable for use as direct-application fertilizers, or in the preparation of bulk-blended fertilizers. The feedstock comprises phosphogypsum, limestone, or mixtures of limestone and sulfogypsum and/or mineral gypsum having...
