Energy requirement for comminution of biomass in relation to particle physical properties

▶ The relationships between specific comminution energy consumption and resulting particle physical properties were determined for the second bioenergy crops including Miscanthus, switchgrass, willows and energy cane. ▶ The paper investigated the impacts of biomass moisture and mill machine variables on energy efficiency of size reduction. ▶ The paper discussed the trade-off between costs of mechanical size reduction and optimal particle size and shape for the bio-conversion to optimize the biomass supply logistics. ▶ The paper analyzed the applicability and improvements of two widely used ASAE standards in biomass mechanical processing and particle analysis.
