Summary

Three binder systems, which exhibited a range of PI values, were used to investigate the effects of die fill on the compaction of granulate. The binders selected for this study were a plasticized PVA. sodium lignosulfonate, and PEG 8000. For comparison, granulate was prepared without an organic binder system. Samples were pressed in an industrial semiisostatic horizontal dry press and evaluated for surface roughness using an optical interferometer. A comparison to samples prepared using the plasticized PVA binder system in a vertical dry press indicated that die fill has a major role in good compaction. The samples prepared using the horizontal dry press had a consistently higher surface roughness due to poor die fill prior to compaction.
