A device for spreading granular materials is described and comprises at least one centrifugal spreader with blades (9) including surfaces (12) for directing the material to be spread, at least one intermediate hole (16) being formed in the surfaces (12) of the blades (9) in order to release some of the material flowing along the surface (12) and to expel it from the blades (9) in an intermediate portion thereof. |
