Abstract: Method and various embodiments of apparatus for producing granulates from pulverulent, granular, doughy or similar material. Material to be granulated is continuously fed into the apparatus and formed into a skin of the material in the nip spaces between adjacent and cooperating rotating curved surfaces. The skin and material alternately progresses and is moved backwards axially of the rotating surfaces and is periodically and repeatedly kneaded as it is conveyed by the rotating surfaces towards and away from and finally forced through outlet apertures whereupon it is divided up into granulates. The apparatus can be in various embodiments which use paired, skinforming rotating curved surfaces and can be the surfaces of rollers or of at least two rollers cooperating with the internal surface of a drum. Helical lands or grooves can be incorporated in one or a combination of the paired rotating surfaces.
