ABSTRACT:
A two-roll machine, in particular a roll press, for interparticle comminution of granular material with two rotatably mounted, counter-rotating driven rolls separated from one another by a roll gap. Drive journals of the roll's shaft-mounted gearboxes are shaft-mounted as step-down planetary gear units. A machine table with a table platen is arranged under each of the shaft-mounted gearboxes that can move back and forth parallel to the roll shaft in at least one direction, and three vertically and horizontally adjustable supporting rests arranged in a triangle are arranged on the table platen on which the respective shaft-mounted gearbox can be supported offset-free and aligned with the roll shaft drive journal during its installation and removal.
