(54)    Title

Twin -roll machine, in particular for material bed milling

(57)    Abstract

The aim of the invention is to configure a twin-roll machine, in particular a roll

press for the bed milling of a granular material, comprising two rotatably mounted rolls (11, 12) that are separated by a nip and driven in opposite directions in such a way that the hydraulic cylinders that are used to exert the roll compression force no longer need to be supported on a heavy-duty machine frame, which complicates the replacement of the rolls, for example, in the event of a repair. To achieve this, the hydraulic cylinders (15, 16) are located in such a way that they respectively engage with both the bearing housings (14) of one roll (12) and the opposing bearing housings (13) of the other roll (11) , forming a closed milling compression force system without the need for a closed machine frame that bears the roll compression forces.
