Abstract:

The present invention relates to a device for distributing solid pulverulent materials, transported pneumatically, in an annular section of large diameter, in particular for feeding vertical calcining kilns. The device to which the invention relates is characterised in that it comprises an annular chamber (32) with an axis which is vertical or close to vertical, which is closed at its upper end and the section of which, in a plane perpendicular to the axis of the device, has an area which is constant in its upper part and then decreases progressively as far as its lower end where an annular outlet opening (28) is provided, and in that the pipe (40) for admission of the flow of gas transporting the solid materials is connected to the upper part of said chamber so that said flow penetrates the latter in an approximately radial direction.
