Pulverization of Woody Biomass by a Continuous Vibration Mill

Abstract

A continuous type vibration mill was developed for the effective pulverization of woody biomass. A conventional vibration mill was upgraded the continuous pulverization system to increase woody biomass pulverization yield. To increase the yield, a weir was mounted at the exit of the vibration cylinder, by which the pulverization time was controlled. A closed pulverization system was also developed to increase the throughput of woody powder. As a result, the upgraded continuous type vibration mill was able to improve the yield of woody powder and pulverization efficiency dramatically.
