Finding of the mechanical power distribution in a horizontal ring mill using infrared thermography. by G. Zannis*, M. Founti*, P. Makris* Laboratory of Heterogeneous Mixtures and Combustion Systems, School of Mechanical Engineering

 · Abstract. The fragmentation mechanism of low-grade hematite ore in a high pressure grinding roll (HPGR) was studied based on the characteristics of comminuted products at different specific pressure levels. The major properties included the reduction ratio, liberation, specific surface energy, and specific surface area.
