Optimization of mill performance by using SciELO
Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.
