    Abstract: The invention relates to a device for charging at least two separate layers of fine grain materials in a hearth (2) of a rotary furnace. The inventive device has at least two discharge bunkers (221, 222) for the fine grain materials. Said bunkers are aligned in the direction of rotation of the hearth (2) and are each provided with a discharge orifice (341, 342) and a discharge edge (361, 362) allocated to said discharge orifice (341, 342). The discharge edges (361, 362) are vertically staggered and form, in each case, the end segment of the discharge surface of a discharge bunker (221, 222, 223, 224, 225) inclined towards the discharge orifice (341, 342, 343, 344, 345), said surface being located at the base of the material column in the bunker.

    Abstract: A device for continuously depositing alternate stacked layers of at least two fine materials on a moving carrier (1), said layers having constant or varying controlled thicknesses, is disclosed. The device includes main hoppers (4A, 4B) and means (5) for removing the fine materials from the main hoppers and delivering them to secondary hoppers (6A, 6B) arranged above said moving carrier. The device includes at least as many secondary hoppers as there are layers to be deposited, and each secondary hopper is provided with a lower opening for dispensing the fine material therein. The opening includes a rear wall (7) extending down to a point slightly above the previous layer, while the front wall (10) extends down to a point selected in such a way that the distance between said point and the surface of the previous layer determines the thickness of the layer deposited by the secondary hopper in question.
