In order to improve fuel quality of biomass, a novel biomass crushing system was presented. In this paper there were different biomasses, namely pine chips, corn stalk and cotton stalk, chosen for size reduction study. The production process was described and physical characteristics (particle size distribution, micro-morphology and bulk density) of biomass powder were investigated. The results show that 95% of biomass powders are below 200 μm in size, and the bulk density is significantly increased after pulverization. The micro-morphology of biomass powder changes with biomass species, corn stalk presents flake, different with the block structure of cotton stalk. Compared with hard straw, finer particles are more easily achieved for the pulverization of soft straw in the crushing system.
