Classification Characteristics of a Centrifugal Powder Classifier.

Mitsuhiro Ito; Hiroyuki Ninomiya; Satoru Fujii

籠状のローターと固定のガイドベーンを内蔵した遠心式分級機において, 分級特性を粗粉側への分割率β, 分級精度指数κ1 (=d25/d50) およびκ2 (=d50/d75) に分けて実用規模で実験的に検討した.βは粉体の供給速度Qpと2つのパラメータβ0およびγを含む式で表現され, β0は本研究で定義した凝集性指数で表現でき, γは分級空間で流体が散逸するエネルギーと分離粒子径で評価できることがわかった.50%分離粒子径が比較的小さい場合あるいは分級空気流量が比較的少ない場合には分級機内での分散が不十分になり易く, κ1は小さくなる.分離粒子径を小さくするためにローターブレードの回転速度を高くした場合, ローターブレード間を通過する空気速度は逆流を伴って不均一になり, 不必要に粗い粒子が細粉側に入り込み, κ2は小さくなることがわかった.なおこの現象はローターブレードの枚数を増すことにより抑制できる.
