An apparatus for wet granulating a powder material comprises:&#x2014;a barrel having a granulation chamber and being provided with a first inlet () for receiving said powder material and for supplying it to said granulation chamber and with a second inlet () for receiving a granulating liquid and for supplying it to said granulation chamber, said granulation having an aperture () for discharge of granules from said barrel, and&#x2014;a transporting means (S) for advancing said powder material toward the end of said granulation chamber while granulating it with the aid of said granulating liquid, said transporting means (S) comprising a first transport zone () at its rear end, an agglomeration zone () downstream from the first transport zone () and a second transport zone () at its front end, said first inlet () and said second inlet () being positioned above the first transport zone (), wherein said aperture () has a shape tightly fitting the terminal portion of the transporting means (S) for directly discharging said granules from the granulation chamber. The apparatus is useful for continuously wet granulating biologically-active ingredient formulations, chemicals, detergents and foodstuffs.
