Abstract

　成形不良の原因となる坏土のフローパターンの押出方向の湾曲の発生を極力抑制し、ハニカム構造体等の成形に好適に用いられる均質性の高い良好な柱状体が得られる土練機を提供する。坏土が内部に流入される供給口１９と、回転軸６と回転軸６に沿った螺旋状の回転羽根５とを有し、坏土を混練するスクリュー４と、坏土が柱状体として押出される押出口２０と、を含むドラム２を有し、ドラム２は供給口１９側において昇圧部１０と、押出口２０側において昇圧部１０より内径が小さい押出部１２と、昇圧部１０と押出部１２との間に位置した整流部１１と、を備え、回転軸６は整流部１１の内側において押出口２０に向かって漸次径が減少し、整流部１１と押出部１２との境界付近に回転軸端部７を備えた土練機３０である。
