Abstract

See full text

A roller mill for comminuting bulk material may include a first grinding roller and a second grinding roller that are arranged opposite one another and can be driven in opposite directions. A grinding gap exists between the grinding rollers. A floating bearing unit may be configured to receive the first grinding roller, and a fixed bearing unit may be configured to receive the second grinding roller. The floating bearing unit includes two bearings, each of which receives one end of the first grinding roller. Hydraulic actuators are mounted on the floating bearing unit for applying a force to the floating bearing unit. The bearings of the floating bearing unit are connected to one another via a synchronization device that includes a coupling element, which in a coupling position prevents a relative movement of the bearings and in a free position permits a relative movement of the bearings.
