Abstract:The conversing relation among the Bond Work Index Wh specific output of mill and the energy efficiency of grinding were developed using dimensional analysis. The relations of which were proved and the value of the coversion coefficient c was also obtained using a new installed device for measuring grindability of ores.With the new simulating algorithm, the mill specifications, output and size distribution of griding products of industrial mills can be calculated based on laboratory measuring results. This algorithm is more accurate and simpler than any of the others.

 

Key words: grindability,  conversion coefficient  ethod,  grinding constant
