The results of the analyses clearly shows that using a sieve of +180µm and its bottom -180µm, the best time for grinding 0.5kg of Itakpe iron ore with 3kg of grinding media and a mill speed of 92 rpm is 8 minutes, yielding 17.10% fines and 82.90% coarse., 0.8 mill critical speed measured 15.20% fines and 84.80% coarse.

An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing. The operating process of an iron ore mill is as follows: first, the ores are poured into the mill, and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height, after which they …

One contribution to minimise the increase is to use more efficient comminution equipment. 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 …
