Abstract
(EN)
The invention relates to a special plate-threaded bar forming part of a system for fastening rubber liners in ball mills for mineral processing. The plate-threaded bar assembly is formed by two pieces: a steel plate with a central threaded perforation, and a threaded bar with a perforation at one end. In operation, the threaded bar is screwed to the plate, the two elements being joined together, forming a fastening system, once in position to install a nut and a washer and tighten. The fastening system secures the liners to the mill shell when the nut is installed at the other end and tightened. When it is desired to release the fastening system (for liner replacement), a split pin is inserted into the hole of the threaded bar. The nut is unscrewed using a pneumatic wrench with a corresponding hexagonal socket, and when the nut makes contact with the pin, it forces the threaded bar to unscrew from the plate. In this way, the threaded bar is completely released from the plate in a single quick and safe process.

Platina/barra hilada especial, parte de un sistema de sujeción para revestimientos de caucho en molino de bolas de tratamiento de minerales. El conjunto platina/barra hilada esta constituido por dos piezas: una platina de acero con una perforación con hilo en su parte central y una barra hilada con una perforación en uno de sus extremos. En operación la barra hilada se atornilla a la platina quedando unidas ambos elementos constituyendo un sistema de sujeción, una vez que este esta en posición para instalar tuerca, golilla y torquear. El sistema de sujeción amarra los revestimientos al manto del molino al instalar la tuerca en el otro extremo y ser terqueada. Cuando se requiere liberar el sistema de sujeción (por reemplazo de revestimientos) se instala una chaveta partida en el agujero de la barra hilada y con el apoyo de una llave neumática con el dado hexagonal correspondiente se desatornilla la tuerca y la tuerca al entrar en contacto con la chaveta obliga a la barra hilada a desatornillarse de la platina. De este modo la barra hilada queda liberada totalmente de la platina en un solo proceso rápido y segura
(FR)
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.
