### A procedure for rapid determination of the Bond work index ...

This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained. This happens only after 7–10 grinding cycles which shows that the procedure is a lengthy and complex one and is therefore susceptible to procedural errors. Starting from the first-order grinding kinetics defined by means of the Bond ball mill this paper discusses a simplified procedure for a rapid determination of the ...
