Abstract
The anvil (10) overall has the shape of a prism with one curved lateral surface (16) and two lateral surfaces (18) (20) which have flanks (26) (28) adjacent to the curved surface (16) and directed along the axis of curvature of this surface (16). These flanks (26) (28) are moreover inclined with respect to a mid-plane of the anvil (10) passing through the axis of curvature of the surface (16). These anvils (10) are arranged alternately in one direction then the other in an anvil ring where they are held by an arch keystone effect to form a circle of anvils.

Anvil for centrifugal impact crusher which overall has the shape of a prism comprising two bases and lateral surfaces, of which one lateral surface is a cylindrical surface with a given radius of curvature and of which two other lateral surfaces have flanks respectively adjacent to the cylindrical surface, these flanks being directed towards the axis of curvature of the cylindrical surface, characterized in that the two flanks are inclined with respect to a mid-plane of the anvil passing through the axis of curvature of the cylindrical surface, the inclinations of the two flanks being identical and in opposite directions.
Circle of anvils for centrifugal impact crusher comprising a cylindrical anvil ring with an interior and lower radial flange for vertically supporting a covering of anvils which overall have the shape of a prism comprising two bases and lateral surfaces of which one lateral surface is a cylindrical surface with the same radius of curvature as the anvil ring and of which two other lateral surfaces have flanks respectively adjacent to the cylindrical surface and directed towards the center of the anvil ring, the anvils being wedged inside the anvil ring by an arch key-stone effect, characterized in that the flanks of the lateral surfaces are inclined with respect to a radial mid-plane of the anvil passing through the central axis of the anvil ring, the inclinations of the two flanks being identical and in opposite directions.
