Milling of cellulosic woody biomass as preprocessing is one of the key technologies for ethanol production by an enzymatic hydrolysis process. The vibratory mill with gear type disks, which improves the vibratory cutting rod mill and could impact to woody cell wall directly, has been developed in order to make suitable woody powder for saccharification process and to realize the large volume milling process with high milling efficiency. And the Japanese cedar powder milled by the vibratory mill with gear type disks realized over 60% saccharification efficiency of holocellulose in 60min mill process time. In this study, the feature of woody powder particle after mill was investigated by the scanning electron microscope. And effect of the particle feature for the saccharification efficiency was examined. As a result, it seemed that cracks on the particle were connected the saccharification efficiency.
