Abstract

L'invention concerne un stator de machine de flottation du type à suspension directe comprenant une bague de tôle d'acier (1) et plusieurs lames (2) qui sont agencées sur ladite bague de tôle d'acier (1). Plusieurs trous sont ménagés de manière égale dans la bague de tôle d'acier (1) le long de la direction périphérique, et les parties inférieures de plusieurs lames (2) sont introduites respectivement dans les trous. Des trous d'écrou sont ménagés entre les lames (2) dans la bague de tôle d'acier (1). Dans la machine de flottation, les parties inférieures des lames sont introduites dans les trous de la bague de tôle d'acier et soudées. Des plaques de protection sont montées sur les parties inférieures des lames de telle sorte que lesdites lames présentent une résistance suffisante. Le stator comprend une structure compacte, et est facile à démonter et remplacer.
