1-5 石炭との混合粉砕におけるバイオマスのミル内濃縮

抄録

In this study, the grinding test were performed using a test roller mill with the mixtures of wood pellet and bituminous coal. As a results, in grinding test, the power consumptions of the mixture were higher than that of the coal. In addition, the differential pressure between inlet and outlet of the test roller mill were also increased. On the other hands, the neutral sugar content of samples in test roller mill were markedly increased from input. These results indicate that wood pellet was condensed in the roller mill. The condensation of biomass is a cause of an increased differential pressure in roller mill, even in low biomass mixing ratio.
