Improvement on the thermal cracking performance of pellets prepared ...
2019.1.15 As the ultrafine iron ore concentrate was used to prepare green pellets, the main problem was the serious cracking during the drying process. The fine particles contacted so closely that the porosity of green pellet was only 16.68%, which finally hindered vapor diffusion, and the cracking temperature was only 370 °C.
