<p>A method for fine grinding of mineral particles consists of producing beads (38), made from steel with a high carbon content, or cast iron, by means of atomisation with a granular size range less than 15 mm and mixing the beads (38) with balls (36), made from steel or cast iron with dimensions between 20mm and 120mm, in a rotating grinding mill, the proportion by weight of beads (38) depending on the granular size of the mineral particles for grinding and the desired reduction ratio.</p> |
