Abstract

A squeezing roller granulator that has a squeezing roller pair composed of a toothed pressure roller and a toothed squeezing roller. The teeth of the pressure roller and the squeezing roller have tooth flanks that are situated between a tooth root region and a tooth tip region. The tooth root region has an outer diameter that is smaller than the outer diameter of the tooth tip region, and the tooth tip region of at least one of the rollers of the squeezing roller pair has three squeezing zones including a middle squeezing zone, which define different distances between the tooth tip regions with a minimum distance in the region of the middle squeezing zone, and the contour of the tooth flanks and the tooth root region of the rollers of the squeezing roller pair defines a maximum cross-section of granulate cushions to be formed.
