ABSTRACT:
Apparatus for agglomerating and drying particulate material, including an agglomerator (4) for forming and discharging wet granules of a predetermined size or smaller, and a dryer (12). The agglomerator utilizes a rotary blade assembly (100) that repeatedly impacts and cuts the wet mixture of material to be agglomerated, which is forced radially outward through the blade assembly under centrifugal and air pressure force. Wet granules pass through an annular screen (104) where they reach a predetermined maximum size. The dryer has an inlet (50) for wet granules from the agglomerator, an outlet (78) for granules having passed through the dryer, and one or more baffles (64) within the dryer defining a spiral path through which the granules pass from the dryer inlet towards the dryer outlet. The baffles are configured such that their pitch increases with distance from the dryer inlet, whereby the cross-sectional area of the spiral path increases toward the dryer outlet.
