Patent ID: 7699254

Claim:
A twin-roller machine for the pressure treatment of granular material with two rotatably mounted, counterrotationally driven rollers which are separated from each other by a roller nip and of which at least one is designed as a loose roller moveable transversely with respect to the roller nip, the bottom and top sides of the bearing housings being mounted on slideways of machine consoles, with hydraulic cylinders being used for pressing one roller against the opposite roller, 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 radial roller pressing forces, wherein the hydraulic cylinders are pressure cylinders which can be pressed against the bearing housings of one roller, on the outer sides thereof that face away from the roller nip, and which transmit their pressing forces via connecting rods, which are situated transversely with respect to the roller nip, to the respectively opposite bearing housings of the other roller.
