Indian hematite fines normally have a high iron grade and minor impurities; they are usually used as sinter fines for feeding into a blast furnace. In this work, the grindability properties of two kinds of Indian hematite fines and the roasting behaviors and induration characteristics of pellets made from these fines were revealed through experiments involving dry ball milling and small-scale and pilot-scale tests. In addition, the microstructures of the particles of ground India hematite fines and fired pellets were investigated using optical microscopy. On the basis of the results, a grate-kiln production line with an annual output of 1.2 Mt of oxidized pellets was established in India. This pellet plant operates stably and reliably, further confirming that preparing high-quality pellets with Indian hematite fines pretreated by dry ball milling is an industrially feasible process. © 2017, University of Science and Technology Beijing and Springer-Verlag Berlin Heidelberg.

China's Refractories 2013年第4期22卷 41-48页

Development and prospect of China＇ s refrac- tory industry equipment/Liu Junguang, WeiTong//Naihuo Cailiao. - 2013,47 （5）：321 Alasttact： China＇ s refractory equipment including me- chanical equipment and kilns developed rapidly in the past two decades by technological innovation, advanced products introduction and independent research and de- velopment based on the former Soviet Union＇ s aid. In recent years, some high efficient equipment was devel- oped covering fields of fine grinding, burdening, mix- ing,shaping and firing,etc. In the new developing peri- od of refractory industry from big to strong, the ad- vanced refractory equipment shall be well researched and developed ,and be well spread taking the opportu- nity of raw materials homogenization and purification, capacity large scale, quality and pollutants reduction. improvement, energy saving
