Effect of Moisture Content and Hammer Mill Screen Size

Also, increasing the hammer mill screen size resulted in increased energy consumption. For lodgepole pine biomass, the medium moisture content of 15 % (w.b.) and a 4.8 mm hammer mill screen size resulted in a lower energy-consumption value of 81 kWh/t, while increasing the moisture content to 18 % (w.b.) resulted in energy consumption of 110 kWh/t.
