ABSTRACT:
A mechanism for the granulometric distribution of solid particles being loaded into a vessel of relatively large dimensions, such as a process reactor, blast furnace, silo, incinerator, dryer, etc., from equipment of small dimensions in relation to the vessel, includes a feed hopper which has an outlet opening that can be variably positioned within the mechanism to introduce the solid particles into a chamber located above the uppermost ends of a plurality of concentric, inclined, preferably conical or pyramidal surfaces. The latter define respective generally downwardly directed free flow paths for the particles to conduct them to a lower location where they enter the upper ends of a corresponding plurality of concentric sets of descending tubes. The discharge ends of the tubes where they feed into the vessel being charged are disposed in a symmetric array. The entire arrangement is such that, during the loading operation, the particles form a continuous bed of solids from the location where they accumulate in the space above the inclined plates to the location where they leave the descending tubes and accumulate in the vessel, so that the formation of "valleys" in the surface of the bed in the vessel and consequent segregation of the particles in the bed are effectively minimized.
