Throw shoe for centrifugal-type crushers with a vertical shaft. Initially, i.e. when it is first used, this throw shoe (1) is not provided with pockets or cavities, but it is provided on its working side (5) with a reinforcement structure (4) made out of a composite material, obtained from an iron-based alloy and highly wear-resistant ceramic tiles, said reinforcement structure being formed in situ when the throw shoe is being cast by infiltration of the liquid metal used to form the body of the piece in a mass of ceramic tiles and binder. The working wear automatically results in the formation of pockets or cavities which, by filling up with the crushed material, exert a protection function against shocks.
Impacteur destiné à des concasseurs centrifuges à axe vertical. Initialement, c'est-à-dire lors de la première mise en service, cet impacteur (1) ne comporte pas de cavités ou poches, mais il est pourvu sur sa face de travail (5) d'une structure de renfort (4), constituée d'un matériau composite obtenu à partir d'un alliage à base de fer et de grains de céramique très résistants à l'usure et formée in situ à la coulée de l'impacteur par infiltration du métal liquide servant à former le corps de la pièce dans une masse de grains céramiques et de liant. L'usure en service provoque automatiquement la formation de poches ou cavités qui, en se remplissant de matière broyée, exercent une fonction de protection aux chocs.
