抄録

In a previous paper, the authors proposed a corresponding Work Index Wi , c which is proportional to the Work Index Wi . Wi , c can be determined from the zero-order increasing rate constant of the mass fraction finer than a cut size in a ball mill grinding.In this paper, the authors proposed an application of Wi , c to the fine particles such as fly ash of which the Work Index was not defined in JIS. The grinding experiments were carried out using the mill made of alumina with a diameter 144 mm and the grinding balls of alumina with a diameter 20 mm. The maximum size of fly ash used is about 75μm. The relationship between Wi , c of fly ash and the cut size was studied. As the results, Wi , c is approximately constant to a certain cut size but increases below it. Wi , c can be useful for evaluating a grindability of fine particles.
