Abstract

PURPOSE: Gypsum with a specific particle size distribution is used as a carrier to remarkably increase granule-forming speed on extrusion and prevent screens from being worn or damage, thus producing integrally granulated agricultural chemicals.
CONSTITUTION: Gypsum containing less than 95% of particles passing through 300 mesh (basing on the Tyler standard sieve) and less than 5% of particles remaining on 42 mesh sieve is used as a carrier to improve the granulation property and produce an integrally granulated agricultural chemical (it means extrusion-molded granules of agricultural chemical or granules of agricultural chemical that is prepared by adsorbing or adhering the effective component to extrusion-molded granules). As the gypsum, may be used both natural gypsum and chemical one (which is synthesized on the course of production of polyaluminum chloride or hydrofluoric acid as a by-product. A binder or other auxiliary agents may be used together.
