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 5 03m x 6 1m 16 5′ x 20′ with a ID of 16′ This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power

The other milling efficiency factors also must be applied to the calculated grinding power While this factor is used in selecting rod mills the inability to measure and define it accurately reduces its value and significance in calculating Wioc and therefore should probably not be used in determining the efficiency of rod mill performance
