Abstract Ball mills can be frequently found in ore grinding facilities These machines show high energy consumption together with a low efficiency As a consequence even a small improvement on the performance of the grinding process can have a huge impact in the operating costs of the plant and in the optimization of
The mill was relined ahead of these tests and some surveys with worn liners were also realized before relining took place Observations have been done without the use of the Sensomag suggest ing a better efficiency of the ball mill for a higher density a better grind for worn liners and high J A semi linear model has been
