Iron Ore Concentrate Particle Size Controlling Through
Nowadays, the HPGR (high-pressure grinding rolls) is an intermediate step between filtering and balling in the most modern iron ore pelletizing operation. The operation debottlenecks filtering process and reduces pressure over the typical milling process to control particle size to the balling. The present study evaluated aspects of microwave line processing. The material used to optimize the process parameters is hard banded iron ore. In this study the sec-ond-order experimental planning, i.e., response surface methodology, was used. Accordingly, the experimental design was developed using the central composite design of the Design-Expert software. Keywords HPGR Grinding Potential of High-Pressure Grinding Roll (HPGR) for Size

Research of iron ore grinding in a vertical-roller-mill
Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here. Within these test works, mill parameters like grinding pressure, separator speed The bond work index test obtained high work index 52.60 kw.h/t and consumed power 11.72 kw.h/t to grind one ton of low grade iron ore and this attributed to the high concentration and hardness ofIron ore grindability improvement by microwave pre-treatment
