Attached to the eccentric studs (25) for supporting and positioning press rollers (b 20) relative to an inner surface of the die (21) of a pellet mill are levers (30). Linked to the levers (30) is a cylinder/piston unit (31) that is provided with a position controller (47) whose position measuring means is constructed as part of the adjusting means (31) for the position of the press rollers (20). In this fashion, the gaps between press rollers (20) and die (21) can be regulated very exactly from the outside.
