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 idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19–75 mm). batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble.
