The residues were briquetted with different particle sizes (PS: 2-5 mm and 7-10 mm) under 80 MPa and 160 MPa. The surface smoothness of them were analyzed by image analyze from their high quality photos. In conclusion, it's seen obviously that the smaller particle sized briquettes had smoother surface than the ones produced with bigger PS. Furthermore, they had better results of compaction, toughness and physical properties.
