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.
