Silo for supply of flock fibres to a carder, which silo is subdivided into superimposed chambers (3,10), between which there is interposed a set of rollers which regulate the descending flow, and carry out breaking and separation of the fibrous material, in which a supply roller (25), an auxiliary supply roller (27) and a breaker roller (26) are disposed in a triangle, in which the surface of the auxiliary roller opposite that which is tangent to the supply roller is exposed to the flow of air which descends downwards, together with the fibres worked by the breaker roller.
