Typical specific power consumption milling coal in a vertical spindle mill is in the order of 8 – 16 kWh/t, depending on coal quality, and double that in a tube/ball mill. The specific power consumption for milling of traditional white wood pellets in a hammer mill is shown in Figure 6 and compared to that for processing Zilkha Black Pellets.
