The invention concerns a system for fixing the mobile jaw on a conical head of a cone or giratory stone crusher, comprising a bowl, with a feed hopper mounted thereon, a fixed truncated jaw mounted coaxially with the bowl, a crushing head mounted on a main shaft coaxial with the fixed jaw and a conical mobile jaw mounted on the head and clamped thereon by means of a locking element integral with the head and pressing on the top of the mobile jaw. Said element (16) has on its outer periphery notches (15) radially oriented outwards and uniformly distributed on said periphery and said mobile jaw (4) has, on its inner periphery, at its openings studs radially oriented inwards, uniformly distributed on said periphery and matching in number said notches (15), the studs penetrating when mounted in said notches so as to secure the locking element (16) and the mobile jaw (4) in rotation when the crusher is operating.

Système de fixation de la mâchoire mobile sur une tête conique d'un broyeur de pierres, à cône ou giratoire, comportant une cuve, surmontée d'une trémie d'alimentation, une mâchoire fixe tronconique montée coaxialement à la cuve, une tête de broyage montée sur un arbre principal coaxial à la mâchoire fixe et une mâchoire mobile conique montée sur la tête et serrée sur elle au moyen d'un élément de blocage solidarisé à la tête et appuyant sur le sommet de la mâchoire mobile. Ledit élément (16), présente sur sa périphérie extérieure des encoches (15) dirigées radialement vers l'extérieur et régulièrement réparties sur ladite périphérie et que la mâchoire mobile (4) présente, sur sa périphérie intérieure, au niveau de son ouverture des tenons dirigés radialement vers l'intérieur, régulièrement répartis sur ladite périphérie et en nombre égal auxdites encoches (15), les tenons pénétrant à l'état monté dans lesdites encoches afin de solidariser l'élément de blocage (16) et la mâchoire mobile (4) en rotation pendant le fonctionnement du broyeur.
