Abstract
A device for feeding and distributing loose material to rotary platforms, particularly for rotary-hearth furnaces, includes a material feed device, a material transfer device and a material gravity-pour duct. The device further includes a static device for the differentiated distribution of the material. The distribution front of the gravity-pour duct has an essentially curvilinear profile, the derivative of this curve being an increasing linear function of the radius of the rotary platform in the portion lying between the center of the platform and its perimeter.
