slag granulation definition English GlosbeGranulation techniques and technologies recent progresses

The steel slag is collected into a steel slag ladle and the ladle is transported to a tilt type equipment by a hoisting device the said tilt type equipment is started to feed the steel slag into a metallurgy granulator and the steel slag is granulated into granulated slag by the said granulator said granulated slag is fed into a drying room 02 18 32 Dry granulation uses mechanical compression slugs or compaction roller compaction to facilitate the agglomeration of dry powder particles while the wet granulation uses granulation liquid binder/solvent to facilitate the agglomeration by formation of wet mass by adhesion Among these two techniques wet granulation is the most widespread granulation technique used despite the fact that
