Roller mill with a synchronizing device

A roller mill for comminuting bulk material, comprising:

• a first grinding roller and a second grinding roller that are arranged opposite one another and are configured to be driven in opposite directions, wherein a grinding gap exists between the first and second grinding rollers;
• a floating bearing unit configured to receive the first grinding roller, wherein the floating bearing unit includes two bearings, each of the two bearings being configured to receive an end of the first grinding roller;
• a fixed bearing unit configured to receive the second grinding roller;
• hydraulic actuators mounted on the floating bearing unit, the hydraulic actuators being configured to apply a force to the floating bearing unit;
• and
• a synchronization device, wherein the two bearings of the floating bearing unit are connected to one another via the synchronization device, wherein the synchronization device includes a coupling element that in a coupling position prevents a relative movement of the bearings and in a free position permits a relative movement of the bearings.
