Relationships between ratio of mass of iron ore finer than 200 mesh to mass of coal finer than 100 mesh for 10 min grinds, and mass ratio coal in feed mixture. Figs. 5 and 7 have the same meaning. From the above, it was found that in the simultaneous grinding of the 1:1 coal-iron ore mixture, iron ore was a help in fine grinding of the coal.

The largest reduction in throughput in AG milling (45%) was observed for the softest ore (GAL-IF) operating in closed circuit, which could be explained by the inability of the ore to perform as autogenous grinding media, given its fineness (Fig. 4) and low competence (Table 4). This was also the ore associated with the largest increase in SSE.

The broken mass of iron ore particles in the 3 and 4 layers has little change, but the broken mass of iron ore particles in the monolayer is slightly smaller than that in the 2 layers. As for the above phenomenon, the broken mass of iron ore particles first increases and then decreases with the number of particle layers.

In multi-layer particle impact experiments, the captured thickness of ore particles is approximately 2 layers during the crushing process. The broken mass of iron ore particles is proportional to the number of concessive impacts at different impact energies. This paper provides theoretical and methodological support for the evaluation …

Crushing and Grinding of Ores or Pulverisation of Ores : The ores generally occur in nature in the form of huge lumps. These lumps are broken into small pieces with the help of grinders or crushers so that the chemical changes which have to take place later on may become convenient. This process is called crushing, which is done by jaw …
