Rectification of nuclear fuel pellets by grinding, augments flow induced by rotating grindstones by forced extraction, to remove dust produced

Dust produced is contained statically and dynamically, as closely as possible to the working and driving grindstones (10, 20). Virtually all dust produced is driven towards the base of the working grindstone (10), and confined at the edges of the two grindstones, in a gaseous flow. This is induced b...

Beschreibung
Zusammenfassung:	Dust produced is contained statically and dynamically, as closely as possible to the working and driving grindstones (10, 20). Virtually all dust produced is driven towards the base of the working grindstone (10), and confined at the edges of the two grindstones, in a gaseous flow. This is induced by rotation of the working grindstone and by forced suction. Virtually all dust generated, confined and driven in this way is removed by forced extraction. An Independent claim is included for corresponding equipment. La présente invention a pour objet un procédé et un dispositif de rectification d'objets cylindriques (30), notamment de pastilles de combustible nucléaire. Dans le cadre dudit procédé, de façon caractéristique, les poussières générées à la rectification, par action d'une meule de travail (10) sur lesdites pastilles (30), restent confinées et sont quasi toutes entraînées côté de ladite meule de travail (10) pour y être prélevées par une aspiration forcée.
