  • Method and apparatus for rectifying cylindrical articles, in particular nuclear fuel pellets
    Patent number: 6729948
    Abstract: The present invention relates to a method and apparatus for rectifying cylindrical articles, in particular nuclear fuel pellets. In said method, in characteristic manner, the dust generated by the rectification by a working grind wheel acting on said pellets remains confined and practically all of it is entrained beside said working grind wheel so as to be taken away by forced suction.
