ABSTRACT:
A powder agglomerator and its method of use. The invention is used to take extremely fine flue dust particles in a collection bin and process them before sending the resultant agglomeration to storage or a further processing location. From its collection bin, the dust particles are discharged by gravity upon a lower rapidly rotating smooth horizontal disc. The bin discharge is offset slightly from the disc's center so that the particles are subjected to centrifugal force to move them to the disc's outer periphery. At the point where the particles are discharged on the disc, a liquid binder, like water, is sprayed on the particles to cause them to begin to agglomerate. After being sprayed, the wetted particles are agglomerated under the influence of centrifugal and tangential forces. When they reach the disc's raised edge, the particles are completely agglomerated at which time they fall over the edge into a discharge hopper located below. Except for its slightly raised peripheral edge, the horizontal disc surface is almost perfectly smooth. The disc's shape including its slightly raised peripheral edge insure a short residence time for the wetted particles before they are agglomerated and discharged.
