PURPOSE:To spread a pulverulent material uniformly by providing a reflecting plate which is directly faced to an opening of a conduit and permits to regulate the spacing between the plate and the opening, in the case of spreading a pulverulent material into a dissolving tank, a kneading device, a reaction vessel or the like. CONSTITUTION:In the spreadder for pulverulent material, the opening of the conduit 2 for supplying the pulverulent material together with a carrier gas is directed downward and is diposed vertically at a central position of the spreading surface, and the reflecting plate 3 having a circular disc shaped surface, a spherically shaped surface or a conically shaped surface projecting toward the opening of the conduit 2 is provided at a predetermined distance from the opening. The spacing between the reflecting plate and the conduit is fixed after adjusting it by screw threads cut into struts 11 for the plate 3 and nuts 13 for adjusting the position of the plate 3. The pulverulent material supplied into the conduit 2 is jetted from the opening of the conduit 2 in the condition of being mixed with the carrier gas, then collides against the reflecting plate 3 and is spread on the spreading surface. |
