Abstract: The mill includes a milling chamber (1) containing a rotor (2) provided with hammers (4), and at least one impact screen mounted pivotably with the aid of an adjusting jack in order to move the bottom end of the screen toward or away from the rotor so as to define, between the bottom end of the screen and the free end of the hammers, a spacing which determines a given particle size. The mill includes a device for positioning the rotor that includes indexing elements for positioning the end of one of the hammers as close as possible to the screen for adjusting the spacing. It includes a geared motor driving a pinion capable of engaging with a toothed wheel fixed in rotation to the rotor so as to rotate it from a rest state until one of the hammers is as close as possible to the screen.

Abstract: The system connects a power supply conductor to an electrical de-icing device of a blade by at least one cable with a first section connected to the power supply conductor by a connector and to a second section with an aerial brace in a flattened half-loop, connected to the de-icing device of the blade by a second connector, installed on the blade, by means of a third rectilinear and flat section, and of a second aerial brace. The first brace, of non-shielded structure, with an elongated part of flattened substantially rectangular transverse section, and with the concavity turned towards retaining and articulation means of a retaining part of the blade to the hub, is connected to the part by an articulation at least pivoting around a substantially parallel axis of pitch of the blade.
