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 …

An effect of a grinding method, that is ball mill and high pressure grinding rolls (HPGR), on the particle size, specific surface area and particle shape of an iron ore concentrate was studied. The particle size distribution was meticulously examined by sieve, laser and image analyses. To measure...

Notwithstanding, in a similar case, in a ball mill used in an iron ore mining plant [7], it was possible to conclude that, similarly to what happens in the case studied, crack nucleation and fatigue crack propagation occurred from geometrical stress concentration holes located near maintenance manholes at approximately mid-span of …
