Method of agglomerating powders and non-flowing fine particle minerals such as clay, silicas, and silicates including the steps of establishing a minimum level of wetting agent content in the material to be agglomerated, tumbling the material to be agglomerated over itself within a rotatably mounted drum, adding additional wetting agent to the material within the drum, and removing the agglomerated powder, which is now formed into pellets of an advantageous pellet size distribution, from the drum. The wetting agent may be added by strategically positioned nozzles within the drum. The establishing of a minimum level of wetting agent content in the powder, preferably in the range of 11/2 to 5%, is achieved either by incomplete drying of the material during wet processing or by the application of a wetting agent prior to introduction into the drum.
