Pelletized wood waste was ground to fine sizes in the Szego Mill. • The specific energy E for particulate 80 wt.% < 1000 μm ranged from 8 to 30 kWh/t.. E was ~ 10 times that for the same size products of brittle materials such as coal. As a first approximation, mill power is independent of the type of material ground.
