Rotary size reduction equipment were instrumented to identify important operating parameters with the aim of minimizing energy consumption while reducing the size of lignocellulosic biomass. Size reduction equipment included a knife mill, hammer mill, and disc mill. Monitored parameters included input power and particle size distributions.. Operating parameters included angular velocity, mass rate, screen size, and biomass selection. Results indicated optimum operating conditions with minimal energy input. Geometric mean dimensions of biomass particles varied from 5x for particle length to 0.3x for particle width when comparing actual to ASABE sieve results – highlighting the need for better consensus standards on particle size reporting.
