Abstract
A grinding roller for roller or rolling mills, and its method for manufacture. For inexpensive manufacture and for increasing the service life, accompanied by limited repair expenditure, a roller jacket is manufactured in one piece for mounting on a radially inner roller body. The roller jacket has rated breaking points, along which the roller jacket breaks with radially directed breaking faces in the event of a corresponding stressing. By means of a holding device both the roller jacket manufactured in one piece and the optionally formed roller jacket breaking segments are fixed in an operationally safe manner.
