Abstract:
In our previous research, a vibration mill using cogring mediums called “tandemring mill”, which replaces the ball medium with a cogring medium in conventional vibration mill, was developed to achieve highimpact pulverizing and in order to attain effective pretreatment of lignocellulosic biomass for producing the bioethanol. In this study, element of a continuous pulverization for improve total throughput and a horizontal, unidirectional shaker that reduced the required driving power were developed to enhance energy conservation on tandemring mill. At first, a passage element examination of a continuous pulverization was carried out using cogring mediums installed in a mill chamber that equipped inlet and outlet on both side of mill chamber. As a result of this, a passage rate of pulverized power was increased with the number of 20 times passage repetition from 0.5kg/min to 3kg/min. Average particle diameter of wood powder was decreased with the number of 10 times passage repetition from 0.1mm to 0.03mm. Then a comparative test of horizontal shaking vs. circular shaking was carried out. As the result, a consumed power of motor at horizontal shaking tandem ring mill was decreased compared with the circular shaking tandem ring mill.
