摘要 |
<p>[Problem] To provide a classification device in which product fine powder little in mixture ratio of coarse particles can be obtained. [Means for Resolution] A classification device characterized in that a setting pitch P between stationary fins 13 and a width L of each stationary fin 13 are combined so that a value of P/L is in a range between 0.042×(¸-50)+0.64 and 0.019×(¸-50)+0.22 in 50°‰¤6‰¤70° when ¸ is an inclination angle of each stationary fin 13, P is the setting pitch, and L is the width in a direction of circulation of particles.</p> |
