The strand width and length depend s on the capacity of the machine and variesProcess for transforming fines of iron or manganese into,,Therefore, a great number of iron ore and/or manganese mining companies are faced with the problem of disposing of considerable stocks of ore fines (i.e. ore with a substantial proportion of particle sizes below 150 microns) which fines cannot be used for sintering. Part of these fines, however, can be pelletized, after which they are used directly in the steel-making furnaces without being sintered.Control of the grain size distribution of T the raw,,(−1 mm) content of the ore, as well as the −0.15 mm and percentage of intermediate (+0.1 -1 mm) size fractions7. For most iron ores, an increase in particle size close to the 0.1 mm size range has the greatest effect on reducing permeability and increasing the amount of moisture that is required for granulation7.
