Energy consumption of two stage fine grinding of Douglas fir ...

The first two Measurement examples are given to show how to 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
