RT Journal Article SR Electronic A1 Alp Kagan Gürdil, Gürkan A1 Demirel, Bahadir T1 Effect of Particle Size on Surface Smoothness of Bio-Briquettes Produced from Agricultural Residues JF Manufacturing Technology Journal YR 2018 VO 18 IS 5 SP 742 OP 747 DO 10.21062/ujep/170.2018/a/1213-2489/MT/18/5/742 UL https://journalmt.com/artkey/mft-201805-0008.php AB This study analyzed the surface smoothness of some fuel briquettes produced from hazelnut, corn and sunflower residues. 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.
