abstract = "Dry switchgrass, wheat straw and corn stover were ground using a laboratory cutting mill with 2 mm square hole screen. The ground biomass was fractionated into 12 size fractions (2 mm down to 0.09 mm) using stacks of wire mesh sieves. The contents left on each sieve were subjected to bulk and specific density, and angle of repose measurements. The bulk density of wheat straw and corn stover decreased with increasing particle size while the bulk density of switchgrass increased with increasing particle size. The Hausner ratio (the ratio of tapped bulk density over loose filled density) decreased linearly with increasing particle size. The measured angle of repose characterized switchgrass as a free flowing particulate whereas it characterized wheat straw and corn stover as cohesive particles. Individual particle size analysis by microscopy on wheat straw and switchgrass showed the ground particles were thin rectangular slabs. Switchgrass particles had a higher aspect ratio (length over width) of 3.55 whereas the wheat straw particles with an aspect ratio of 2.99.",
