## Compressive strength - an overview | ScienceDirect

1996-1-1 · The compressive strength of preheated pellets is increased further to 500 N per pellet even at a lower preheating temperature of 1050 °C when a blend comprising 30% magnetite concentrate and 70% specularite concentrate is pretreated using an HPGR. This meets the minimum requirement for a rotary kiln and the preheating time can be shortened.
