英文要約Title: New Energy Technology Development Project / Renewable Energy Venture Innovation Program (Biomass) / Development of an energy conservation high-impact pulverizing mill for biomass (FY2009-FY2011) FY2009 Annual Report.
The objective of this R&D project was to develop an energy conserving high-impact pulverizing mill which replaces the ball medium with a cog-ring medium called "tandem-ring". It is used for effective pretreatment of lignocellulosic biomass to produce the bio-ethanol. To achieve this, the authors developed a horizontal, unidirectional shaker that reduced the required driving power, a continuous biomass feeder to improve total throughput, a mechanochemical effect to shorten pulverizing time and moisture controller for element examination. The authors investigated the efficiency and passage rate for the biomass feeder, the tandem ring and the mill pod. It clarified that slits on tandem-ring were effective for wear volume reduction and continuous input pulverizing mill could establish a better mill efficiency and passage rate. To get a mechanochemical effect during pulverizing operation, the temperature of the water-cooling jacket around mill pot was controlled during mill operation. The authors observed that no mechanochemical effect was observed over the temperature range. To determine moisture control during pulverizing operation, inflow and outflow of dry air was applied. The authors confirmed that dry air was desirable for efficient desiccation. To determine the effect of the unidirectional shaking in a horizontal direction, a comparative test of horizontal shaking vs. circular shaking was carried out. The authors observed an energy conservation effect when horizontal shaking was utilized. The energy conserving high-impact pulverizing mill was designed with unidirectional shaking and a mill pod inner diameter of 687mm based on the results of these examinations. In addition, a business plan was drawn up to market and sell the energy conserving high-impact pulverizing mill and/or the bio-refinery materials to a wide range of bio-plastic and bio-ethanol manufacturers.
