To understand wear of rotary shear comminution system used for size-reduction of biomass, comprehensive studies of worn components and the extrinsic inorganic particles (EIPs) have been conducted. First, EIPs that came with the biomass during harvesting were characterized. Each component was investigated in terms of the degree of wear, geometry, and mechanical properties according to their materials: 304 SS for spacers, Copper alloy 770 for clearing plates, and A2 tool steel for cutters. Based on the results, the correlation between EIPs and worn components and the wear mechanism were revealed. EIPs caused severe wear of tools, which reduced processing efficiency within a short time. Finally, selected candidate materials and surface treatments were evaluated and compared to the cutter material currently in use. The research was sponsored by the Feedstock Conversion Interface Consortium (FCIC) of the Bioenergy Technologies Office, Office of Energy Efficiency and Renewable Energy, U.S. Department of Energy (DOE).
