Abstract
A roller mill for comminution of bulk material may include a first grinding roller and a second grinding roller that are arranged opposite one another and are configured to be driven in opposite directions. The grinding rollers may be positioned with a grinding gap therebetween. A fixed bearing unit may be configured to hold the second grinding roller, and a floating bearing unit may be configured to hold the first grinding roller. Attached to the floating bearing unit are hydraulic actuators for applying a force to the floating bearing unit. The hydraulic actuators are hydraulically connected to a synchronization device. The synchronization device has a plurality of hydraulic cylinders, each having a piston. The pistons may be connected to one another via a mechanical coupling such that movements of the pistons are coupled.
