SQUEEZING-ROLL GRANULATOR AND USE THEREOF

摘要

A squeeze roller granulator that has a cylindrical pressure roller and a toothed squeeze roller. The gearing of the squeeze roller has 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. The tooth tip region of the squeeze roller has three crushing zones including a middle crushing zone, which define different distances from the cylindrical pressure roller with a minimum distance in the region of the middle crushing zone, and the contour of the tooth flanks and the tooth root region of the crush roller in cooperation with the contour of the cylindrical pressure roller defines a maximum cross-section of granulate cushions to be formed.

1. A squeeze roller granulator that comprising:
a) a cylindrical pressure roller; and b) a toothed squeeze roller, wherein a gearing of the squeeze roller comprises:
i) a tooth flank situated between a tooth root region and a tooth tip region, wherein the tooth root region has a tooth root outer diameter that is smaller than a tooth tip outer diameter; andii) an incoming crushing zone, an outgoing crushing zone, and a middle crushing zone disposed in the tooth tip region, wherein the incoming crushing zone, the outgoing crushing zone, and the middle crushing zone define different distances from the cylindrical pressure roller, and further wherein the middle crushing zone is a smaller distance from the cylindrical pressure roller than the incoming crushing zone and outgoing crushing zone; andwherein a contour of the tooth flank and the tooth root region in cooperation with a contour of the cylindrical pressure roller defines a maximum cross-section of each of a plurality of granulate cushions to be formed.
