METHOD FOR RECONDITIONING A USED GRINDING ROLLER.

摘要

The invention relates to a method for reconditioning a used grinding roller of a bed grinding mill having profiled members which are mounted in bores of the roller element by a part of their length, the other part of their length projecting beyond the surface of the roller element. For the reconditioning, the worn surface of the roller element is turned following removal of the worn profiled members and a material layer is applied in a welding process. The material layer is then provided with bores for receiving new profiled members. Such a method enables a particularly cost-effective reconditioning.
