横型サンドミルの流動挙動と粉砕特性に及ぼすメディア粒子の充填率の影響 Effect of Filling Degree of Grinding Media on Motion of Media Particle and Grinding Characteristics in Horizontal Type Sand Mill
The effect of filled ratio on flow characteristics of grinding media was investigated for a horizontal type sand mill, in which the internal blade and external cylinder counter rotated independently. The relationship between flow characteristics and grinding performance was discussed by carring out grinding tests of calcium carbonate. As a result, it was found that the grinding characteristics obtained for both rotation methods can be well correlated as a function of intensity of velocity fluctuations weighted by appearance frequency and the second power of filled ratio, where the reciprocal collision probability of media particles is taken into consideration.
