Pulverization of Woody Biomass by a Continuous Vibration Mill

In our previous research, a vibration mill using cog-disk mediums, which replaces the ball medium with a cog-disk medium in conventional vibration mill, was developed to achieve high-impact pulverizing in order to attain effective pretreatment of lignocellulosic biomass for producing the bio-ethanol. In this study, a vibration mill using cog-ring mediums, which improves pulverization efficiency and mill volume, was developed in order to make suitable woody powder for enzymatic saccharification. To clarify pulverization efficiency, shapes and size in grinding medium was addressed in pulverization of Japanese cedar wood. And also enzymatic hydrolysis of pulverization powder was carried out. As the results, cog-ring mediums showed effective pulverization at 800g batch milling. The average particle diameter was reduced from 55μm to 20μm in 20mintues. And the crystallinity index was reduced form 44% to 13% in 30minitues. Then saccaharification efficiency of holocellulose was reached over 70% at pulverizing time of 60min. This pulverization expanded the amount pulverizing volume forth to make high saccharification capability powder comparing with the existing vibration mill using cog-disk mediums.
