Abstract
In the design of a twin-roller machine, such as a roll press for comminuting a bed of granular material, with two rotatably mounted, counter rotationally driven rollers which are separated from each other by a roller nip, and which use hydraulic cylinders to provide a roller pressing force the hydraulic cylinders are arranged in such a manner that they act in each case both on the bearing housings of one roller and on the respectively opposite bearing housings of the other roller with a self-contained system of milling pressing forces being formed without a closed machine frame loaded by the roller pressing forces.
