The first two grinding efficiency measurement examples are given to show how to calculate wio and wioc for single stage ball mills figure 1 the first example is a comparison of two parallel mills from a daily operating report mill size 503m x 61m 165 x 20 with a id of 16
The energy specific grinding rate of the coarse material in the ball mill can then be defined as follows the mill specific grinding rate reflects both the efficiency of the mill environment in breaking the coarse particles as well as the grindability characteristic of the ore over the particular size reduction range
Functional performance analysis of ball milling has been described previously by mclvor coarse versus fine or product particle cutoff size is first selected usually equal to some benchmark passing size of the circuit product eg 80 the function of the grinding circuit is to generate new product size material or fines from coarse particles in the circuit feed as efficiently as possible
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates throughput power draw and product grind size from the circuit each of these performance parameters peaks at different filling values in order to contin uously optimize mill operation it is vital to obtain regular measurements of the ball load and pulp position
