A squeezing-roll granulator which has a squeezing roller pair (60) made of a toothed pressure roller (2) and a toothed squeezing roller (3), wherein the toothing (4) of the pressure roller and of the squeezing roller has tooth flanks (5, 6) which are arranged between a tooth base region (7) and a tooth crown region (8 8'), and wherein the tooth base region has an outer diameter (d) which is smaller than the outer diameter (D) of the tooth crown region, and wherein at least one of the two rollers of the squeezing roller pair has three squeezing zones (9, 10, 11) in the tooth crown region comprising a central squeezing zone (10), these zones define different spacings between the tooth crown regions with a minimum spacing (a) in the region of the central squeezing zone, and wherein the contour of the tooth flanks and of the tooth base region of the rollers of the squeezing roller pair defines a maximum cross section of the granulate cushions (12) to be formed. |
