Abstract

L'invention concerne une platine/barre filetée, faisant partie d'un système de fixation pour revêtements en caoutchouc dans un broyeur à boulets de traitement de minerais. L'ensemble platine/barre filetée est constituée de deux pièces : une platine d'acier présentant une perforation avec filet sur sa partie centrale et une barre filetée présentant une perforation à une de ses extrémités. En fonctionnement, la barre filetée est vissée sur la platine, les deux éléments reliés constituant un système de fixation, une fois celui-ci en position pour l'installation d'un écrou, d'une rondelle et le serrage. Le système de fixation maintien les revêtements sur l'enveloppe du broyeur lors de l'installation de l'écrou à l'autre extrémité et après serrage. Lorsque l'on souhaite libérer le système de fixation (pour le remplacement de revêtements), on installe une clavette dans l'orifice de la barre filetée et à l'aide d'une clé pneumatique avec le dé hexagonal correspondant on dévisse l'écrou et lorsque l'écrou entre en contact avec la clavette, il oblige la barre filetée à se dévisser de la platine. Ainsi, la barre filetée est libérée totalement de la platine en un seul processus rapide et sûr.
