This study prepared pre-sintered clusters with fine nickel powders and proposed an effective method to predict control the sintering shrinkage based on cluster size. Experiments were conducted investigate influence of pre-sintering temperature size specific surface area morphology as well validate availability prediction method. The results show that decreases increasing slightly oscillates lin...

Blaine specific surface area (SSA) is an essential physical property of iron concentrate and availably improved by a high-pressure grinding roller (HPGR) to enhance the pelletability qualities oxidized pellets. In this study, four concentrates with various SSA were obtained HPGR treatment produce The results show that high degree lattice deformation corresponds which beneficial for improving qu...
